Product details

171 A continuous drain — what it takes to use it

The TO-220 package with a large copper pad on the heatsink side is the only way to get near that continuous rating.

The maximum on-resistance is 2.4 mOhm at a drain current of 68 A and a gate drive of 10 V.

Logic-level gate drive — 4.5 V minimum

The gate threshold voltage is a maximum of 2.2 V at 100 µA, and the drive voltage range specified for Rds(on) is 4.5 V to 10 V.

Wider temperature range than typical

Input capacitance and switching speed

The input capacitance is 5050 pF at 15 V drain-source.
