FDC610PZ Description

This P-Channel MOSFET is manufactured utilizing ON Semiconductor’s cutting-edge PowerTrench® process, which has been carefully adapted to reduce the on-state resistance while keeping the gate charge to a minimum. This allows the device to provide outstanding switching performance. The load switching and power management, battery charging circuits, and DC/DC conversion are examples of applications that greatly benefit from these devices.

What is P Channel MOSFET?

The term “p channel MOSFET” refers to a specific variety of MOSFET in which the channel comprises the majority of charge carriers in the form of holes. When this MOSFET is turned on, most of the channel’s charge carriers, such as holes, will begin circulating across the channel. This MOSFET is different from an N channel MOSFET, which gets its name because electrons make up most of the charge carriers in an N MOSFET.

The body of the P- channel MOSFET is composed of an n- region, and it contains a P- channel area positioned between the two terminals known as the source (S) and the drain (D). This type of MOSFET, like the N channel MOSFET, also comprises three terminals: the source, the drain, and the gate. This MOSFET uses an n-type substrate, and its source and drain terminals are extensively doped with p-type materials. However, the substrate itself is n-type.


The vast majority of charge carriers in P-Channel MOSFETs are holes, and the mobility of these charge carriers is significantly lower than that of electrons, which are used in N-Channel MOSFETs. The most significant distinction between the p channel MOSFET and the n channel MOSFET is that to activate the p channel MOSFET, a negative voltage must be applied from the Vgs (gate terminal to source), whereas to start the n channel MOSFET, a positive voltage must be applied to the VGS. Given this information, P-Channel type MOSFETs are an excellent choice for high-side switches.

When we apply a voltage less than zero (-) to the gate terminal of this MOSFET, the charge carriers available below the oxide layer, such as electrons, are driven down into the substrate. Therefore, the depletion zone the holes currently occupy is connected with the donor atoms. Therefore, spots will be drawn from the drain area and the p+ source into the channel region when the gate voltage is set to a negative value (-).

How Do You Test P Channel MOSFET?

Utilizing a digital multimeter and proceeding through the steps outlined below will allow you to test a p-channel MOSFET successfully.

● To begin, you will need to adjust the scale on the multimeter so that it reads in the diode range.

● The MOSFET should be positioned so that the printed side faces you atop any wood table.

● Short the drain and gate terminals of the MOSFET using the probe of a digital multimeter. This will permit the device’s internal capacitance to discharge, which is crucial for the MOSFET testing procedure. Because of this, it is important to note that this step is very important.

● Now, position the red color probe of the multimeter on the source terminal and the black color probe of the multimeter on the drain terminal.

● On the multimeter’s display, you will see a reading indicating an open circuit.

● After that, without moving the RED color probe from the MOSFET’s source terminal, remove the black color probe from the drain terminal of the MOSFET, move it to the gate terminal of the MOSFET for a few seconds, and then move it back to the drain terminal of the MOSFET. This should be done before moving the black color probe back to the drain terminal of the MOSFET.

● On the multimeter’s display, you should see a low or a continuity value at this point.

● This should ensure that your MOSFET is operating correctly and without any issues. If you get any other kind of reading besides that, it points to a faulty MOSFET.

P Channel MOSFET Failure Modes

Even with a well-designed circuit, high-quality components, and a brand-new motor, it is not uncommon for the MOSFET to fail for reasons that are not immediately apparent. MOSFETs generally have very high levels of durability; nevertheless, if their ratings are exceeded, they can fail very rapidly. In the following paragraphs, we will discuss some of the most common MOSFET failure modes and offer advice on how to avoid them.

Because we are unsure of the specific events that led to the MOSFET’s failures, it is exceedingly challenging to identify where the losses took place within the device. The following is a list of some failure modes that can occur in MOSFETs, which are listed below.

When a high current is supplied throughout the MOSFET, the device will begin to heat up. Extreme temperatures can potentially cause damage to the MOSFET if there is insufficient heat sinking.

  • Faulty battery.
  • Avalanche failure.
  • Blocked or jammed motor.
  • Fast acceleration or deceleration.
  • Excess power dissipation.
  • Excess Current
  • Load with Short-circuit
  • Foreign objects.

What is P channel MOSFET used for?

When switching loads, P-channel MOSFETs are frequently employed. P-channel solutions on the high side appeal to applications such as non-isolated Point of Loads and Low-Voltage Drives because of the simplicity of these solutions. Space is at a premium in these types of systems.


The on-state resistance of this P-Channel MOSFET is minimized. At the same time, the gate charge is kept to a minimum thanks to ON Semiconductor’s innovative PowerTrench® method, which is used during production. Due to this, the device can boast superior switching performance. Such devices are extremely useful in various contexts, including load switching and power control, battery charging circuits, and DC/DC conversion.
