P55NF06 MOSFET Explained / Description:

P55NF06 is an N Channel MOSFET that is manufactured in different packages the most common package is TO-220 package. It is also searched with STP55NF06, STB55NF06, STP55NF06FP and all are same.

The transistor is primarily designed for power supplies, networking DC to DC power systems, and automobile applications but we can also use it in variety of different applications according to its specs. Moreover, it has many features and benefits which are mentioned below.


Low RDS(on)

The maximum RDS(on) of the transistor is only 0.018 Ω. The low RDS(on) means less resistance when the transistor is ON or driving load and also generates less heat during the operation.


100% Avalanche Tested

It is 100% avalanche tested which means that the device will perform stably in conditions when its drain to source voltage is above from its mentioned drain to source ratings.


 Fast Switching Speed

The MOSFET also features high switching speed which is beneficial for applications that require very fast switching of loads such as UPS circuits.

Other features are Improved dv/dt capability, ultra low gate charge, etc.


Where We Can Use It & How to Use:

As mentioned the MOSFET is primarily designed for power supplies, networking DC to DC power systems and automobile applications but can also be used in a variety of general applications which fall under its ratings such as motor controllers, audio amplifiers etc.



Power Supplies

Solar Chargers

Uninterruptible Power Supplies

Battery Chargers

Battery Management Systems

Audio Amplifiers

Motor Controllers

Safe Operating Guidelines / Absolute Maximum Ratings:

To safely operating the device follow the guidelines below:

  1. Do not use the transistor to its absolute maximum ratings and always use it 20% below from its max ratings.
  2. The maximum continuous drain current is 50A therefore do not drive load of more than 40A.
  3. The maximum drain to source voltage is 60V therefore do not drive load of more than 48V.
  4. Always use a suitable heatsink with the MOSFET.
  5. Always store or operate at temperatures above -55 °C and below +150 °C.
