Product details

P-channel 100 V HEXFET in a D-Pak — what it is and where it fits

The IRFR9120NTRLPBF is a 100 V P-channel MOSFET from Infineon's HEXFET family, rated for 6.6 A continuous drain current at 25°C case temperature. Packaged in a surface-mount D-Pak (TO-252), it is designed for high-side load switching, battery protection, and DC-DC converter applications where a positive supply rail needs to be switched off. The P-channel polarity simplifies gate drive — no charge pump needed when the source is tied to the positive rail — making it a common choice for automotive body controllers, industrial solenoid drivers, and power management in telecom line cards.

Temperature range and environment

Operating junction temperature spans -55°C to 150°C, qualifying it for under-hood automotive, outdoor telecom cabinets, and industrial motor-drive environments where ambient heat soaks the PCB. The 27 nC gate charge at 10 V keeps gate-drive losses manageable in PWM applications switching at tens of kilohertz; input capacitance of 350 pF at 25 V Vds means the driver sees a moderate load, compatible with most gate-driver ICs.

Lifecycle and sourcing

Listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window on record. For a BOM line that needs a P-channel 100 V D-Pak switch, this is a stable, in-production option with no imminent obsolescence risk.

Frequently asked questions

What is the Rds(on) of IRFR9120NTRLPBF?

The maximum on-resistance is 480 mOhm at a gate-to-source voltage of 10 V and a drain current of 3.9 A. This is the figure used for conduction loss calculations in the design.
