Product details

30 V, 140 A N-channel — what the ratings mean for the load

The Infineon IRL3803SPBF is a HEXFET N-channel power MOSFET rated for 30 V drain-source and 140 A switching current. The 6 mOhm max on-resistance at 71 A and 10 V gate drive determines conduction loss.

The 175°C maximum junction temperature is the absolute ceiling.
