Product details

75 V, 240 A — the rail switch that handles the surge

The IRFS7730TRL7PP: The 2 mOhm max on-resistance at 100 A, 10 V gate drive sets the conduction loss floor for a high-current rail — at 100 A the dissipation is just 20 W from Rds(on) alone, which the 375 W power rating can sink with adequate heatsinking.

Gate charge tells you what driver it needs

Total gate charge is 428 nC at 10 V. Input capacitance is 13970 pF at 25 V.

175°C junction — keeps running where others derate

The junction temperature range is -55°C to 175°C. The gate threshold voltage is 3.7 V max at 250 µA.

Frequently asked questions

Can I use IRFS7730TRL7PP for high current switching?

Yes, it is rated for 240 A continuous drain at 25°C case temperature and 75 V drain-source. The 2 mOhm Rds(on) at 100 A keeps conduction losses manageable, but the 428 nC gate charge means the gate driver must supply high peak current for fast switching edges. The 175°C junction rating gives headroom for thermal transients in high-duty-cycle applications.

Is IRFS7730TRL7PP RoHS compliant?

Yes, it is ROHS3 compliant per the lifecycle record.
