FDP33N25 Description

Short technical summary and product information.

The FDP33N25 is an N-Channel power MOSFET from onsemi's UniFET family, designed for high-voltage switching applications. It features a drain-source voltage rating of 250V and a continuous drain current of 33A at case temperature 25°C (20.4A at 100°C). The device offers a maximum on-resistance of 94mΩ at VGS = 10V and ID = 16.5A, contributing to efficient conduction in power conversion circuits.

 

This MOSFET is built on planar stripe and DMOS technology, providing improved switching performance and higher avalanche energy strength. It has a typical gate charge of 36.8nC and an input capacitance of 2135pF, supporting fast switching transitions in demanding power supply designs. The device is 100% avalanche tested and can handle a single pulsed avalanche energy of 918mJ, making it suitable for robust industrial applications.

 

The FDP33N25 is housed in a through-hole TO-220-3 package (TO-220-3LD), which facilitates easy mounting on PCBs and provides effective thermal transfer to a heatsink. The thermal resistance from junction to case is 0.53°C/W, and the maximum power dissipation at 25°C is 235W, with a derating factor of 1.89W/°C above 25°C. The device operates over a junction temperature range of -55°C to +150°C.

 

Typical applications include power factor correction (PFC), flat panel display (FPD) TV power, ATX power supplies, uninterruptible power supplies (UPS), lighting, and electronic lamp ballasts.
