P-Channel 30 V HEXFET in DirectFET MX
The IRF9383MTRPBF is a P-Channel enhancement-mode MOSFET from Infineon's HEXFET family, rated for 30 V drain-to-source and 22 A continuous drain at ambient (160 A at case) with a maximum Rds(on) of 2.9 mOhm at 10 V gate drive. The DirectFET Isometric MX package is a large-die, solderable-can design that conducts heat directly into the PCB — layout must match the footprint for low inductance and effective thermal vias. Applications include high-side load switching, battery protection, and DC-DC converter synchronous rectification in power supplies and automotive systems.
Package and thermal path
The DirectFET Isometric MX package is a leadless can with a large solderable backside that doubles as the drain connection and primary thermal path. The 113 W case-rated power dissipation assumes a well-designed PCB with thermal vias under the can to spread heat into the board copper. The junction temperature range of -40°C to 150°C covers automotive under-hood and industrial environments. Surface-mount assembly requires a solder profile compatible with the can finish — no through-hole, no heatsink clip.
Lifecycle and compliance
The IRF9383MTRPBF is listed as Active with ROHS3 compliance.
