STPS1545CT Specification

• Because it has a low voltage drop and a quick switching speed, this component is an excellent choice for implementing high-frequency circuits when used as a Schottky diode.
• The term “dual common cathode” describes a diode configuration in which the negative electrode, known as the cathode, is shared by both of the device’s terminals.
• The component is contained within a TO-220AB package, which is a through-hole type of package that is intended to be soldered onto a printed circuit board. The component is housed in this sort of packaging.
• It is customary to refer to the TO-220AB package as the “Supplier Package” or simply the “TO.”
• The total number of pins (3 total) This is the maximum number of connections that can be made to the device via its physical ports.
• The value “Lead Shape: Through Hole” indicates that the leads that emerge from the package have a configuration known as “through hole,” which may be seen in the value.
• 45 volts is the maximum voltage that can be repeatedly applied to the gadget in the opposite direction without inflicting any kind of damage to it.
• Maximum Forward Continuous Current (in Amperes): 7.5 – This is the maximum current that can flow in the forward direction continuously that the device can safely manage.
• The maximum amount of current that can flow through the device in the forward direction for a limited period of time, such as during a transient event, is 150 A. This is the highest amount of current that can flow through the device in the forward direction. This is the maximum current produced by a non-repetitive surge.
• The diode has a peak forward voltage of 0.84V when subjected to a current of 15A. This voltage drop occurs across the diode when it is operating to conduct current in the positive direction.
• If a voltage of 100 volts is applied opposite to the device, then a current of 100 microamperes (A) will flow through it.
• Even at temperatures as low as -65 degrees Celsius, the device can carry out its intended purpose.
• The device can function at temperatures up to 175 degrees Celsius without risking damage.

As a Schottky diode, the STPS1545CT is versatile enough to be utilized in various electronic contexts. Because it has a low switching delay, a high surge current capability, and a quick switching speed, it is ideally suited for applications requiring rapid and effective power supply management.

What Is a Schottky Rectifier and How Does It Work

If you need to correct power in an electrical circuit, look for a Schottky rectifier. Since Walter H. Schottky was the one who came up with the idea for the device, he is the one who should receive credit for naming it.

In order to create a Schottky rectifier, a metal-semiconductor junction must be utilized. This junction requires a metal, such as platinum or titanium, to contact a semiconductor, such as silicon or germanium. Applications operating at high frequencies and speeds can benefit tremendously from the Schottky rectifier’s metal-semiconductor junction. This junction has a smaller voltage drop and a faster switching speed than a standard p-n junction diode.

To operate properly, it is necessary to apply a forward voltage across the Schottky rectifier. Once this voltage has been applied, current can flow through the metal-semiconductor junction. The metal side of the junction injects electrons into the semiconductor side of the junction, which causes the semiconductor side to have an excess of holes (or a deficiency of electrons), which are then filled by the electrons injected from the metal side. When this is done, the current is allowed to flow through the device, which enables it to perform the role of a rectifier.

In most circumstances, the forward voltage drop of a Schottky rectifier is somewhere in the range of 0.2 to 0.5 volts. Compared to p-n junction diodes, these devices can resist higher voltages and currents while producing less heat and losing less power.

Conclusion

The STPS1545CT rectifier from STMicroelectronics is a great solution for converting alternating (AC) to direct (DC) in a circuit. Its peak non-repetitive surge current of 150 A and maximum continuous forward current of 7.5 A make it a potent and dependable option, and the tube packing ensures that the parts arrive unharmed.

It is usable in various electrical layouts because of its twin common cathode arrangement and wide (-65 to 175) temperature operating range.
