VX7805-500-W Introduction

These days, DC-DC converters are a must-have for any electronic device, but notably those requiring portability or using batteries. They aid in reducing the high input voltage to the safer, lower level needed by the load without sacrificing efficiency or stability. One example of such a DC-DC converter is the VX7805-500, which has two regulated outputs (one at +5V and one at -5V) and can supply up to 500mA 300mA, respectively. This article will serve as a comprehensive reference for the VX7805-500, covering everything from its electrical characteristics and pinout to its possible uses and design concerns.

VX7805-500-W Features

● High Gain in Current Flow:

The current gain of the KSC1845FTA transistor is quite high, with a typical value of 350 when the input current is 10mA. Because of this, a relatively low input current can be amplified to produce a significantly higher output current, making it an excellent component for use in circuits containing amplifiers. Because of the high current gain, even relatively weak signals can be amplified to a significantly higher volume, a feature that is particularly helpful for applications involving audio amplifiers.

● Low Noise:

The KSC1845FTA transistor has a low noise figure, with a typical value of 1.5dB at 1kHz. This number is based on the noise figure measured at 1kHz. This indicates that it is capable of amplifying signals without significantly increasing the amount of noise that is present in the signal. Due to the fact that it has a low noise figure, it is an ideal candidate for use in low-noise circuits. This is especially true in audio applications, where maintaining the integrity of the signal is essential.

● Low Saturation Voltage:

The KSC1845FTA transistor has a low saturation voltage, with a typical value of 0.2V. This value refers to the voltage value when the transistor is fully saturated. This indicates that there is just a minimal decrease in voltage across the transistor when it is operating at its maximum potential. Because of this, it is useful as a switch in circuits where there is a concern about power dissipation, such as in circuits that supply power.

The KSC1845FTA transistor has a high breakdown voltage of 60V, making it a good choice for high-voltage applications. This indicates that it can withstand high voltage levels without suffering any damage. Due to the high voltage at which it breaks down, it is appropriate for high-voltage applications.

● Tiny Form Factor:

The KSC1845FTA transistor has a small form factor, enabling it to be easily integrated into circuits even when limited space is available. Because of its little size, it is ideally suited for installation in portable electronic devices such as mobile phones and portable audio players.

● Low Price:

The KSC1845FTA transistor is a cost-effective alternative that may be used in various electronic applications. Because of its low price, it is a good option for both amateurs and professionals looking to keep their projects’ overall cost to a minimum.

In a nutshell, the KSC1845FTA transistor is a highly adaptable electronic component that comes equipped with several practical characteristics that make it an outstanding option for a wide variety of circuit configurations. It is ideally suited for amplifier and switching applications due to its high current gain, low noise, low saturation voltage, and high breakdown voltage. Moreover, its tiny form factor and low cost make it an attractive choice for various electronic projects.

● Maximum Current – Collector (Ic): 50 milliamperes

The collector current (Ic) that the transistor can handle up to a maximum of is 50mA. This indicates that the transistor has the capability to amplify signals up to a maximum of 50mA and switch between them.

● Maximum voltage for the collector-emitter breakdown is 120 volts.

The collector and emitter pins of the transistor may withstand up to 120 volts of power between them at their absolute maximum. This quality becomes extremely significant when the transistor is used in situations involving high voltage.

● Maximum Vce Saturation Voltage at Ib and Ic: 300 mV at 1mA and 10mA

At varied levels of base current (Ib) and collector current (Ic), the transistor can produce a maximum collector-emitter saturation voltage (Vce Saturation) of 300 millivolts. This occurs when the collector current is 10 milliamperes, and the base current is 1 milliampere. This parameter is crucial when the transistor is employed in switch mode since a small Vce Saturation value means less power is dissipated, and less heat is generated.

● Maximum current through the collector cutoff: 50 nA (ICBO)

The transistor’s collector cutoff current (ICBO) can produce a maximum of 50 nA. This current can pass through the collector when the transistor operates in cutoff mode.

● Maximum DC Current Gain (hFE) at Ic and Vce: 300 at 1mA and 6V

At a base current of 1 mA and a collector-emitter voltage of 6 V, the transistor can provide a minimum DC current gain (hFE) of 300. This value is independent of the collector current (Ic) levels, and collector-emitter voltage (Vce) applied. Because the gain of the transistor increases the input signal, it is crucial to pay attention to this parameter while the transistor is being utilized in amplifier mode.

● Power – Max: 500 mW

The transistor has a power dissipation (Pd) capacity of up to 500 milliwatts at its absolute maximum. This is the maximum amount of electricity that can be converted into heat without permanently damaging the transistor.

● 110 MHz is the frequency for the transition.

The term “transition frequency” refers to the frequency at which the transistor’s current gain (hFE) decreases until it reaches unity. The frequency of transition is 110 MHz for the KSC1845FTA transistor. This characteristic becomes essential when the transistor is employed in circuits that operate at high frequencies.

● Operating Temperature: 150°C (TJ)

The transistor can work at temperatures up to 150 degrees Celsius without being destroyed, at their absolute highest (TJ). This value becomes critical when the transistor is employed in applications with high temperatures.

● Mounting Method: Through Hole (Through Hole)

Through-hole mounting is one method that can be utilized when attaching the KSC1845FTA transistor to a printed circuit board.

TO-226-3 and TO-92-3 are the package or case designations (TO-226AA) Created Prospective Customers

Two packages for the KSC1845FTA transistor are chosen: a TO-92-3 package or a TO-226-3 package with formed leads. Small signal transistors often come in the TO-92-3 package, while power transistors typically use the TO-226-3 package, which has a bigger footprint. The TO-92-3 package is the more common option.
