IRF9540SPBF Description

Short technical summary and product information.

The IRF9540SPBF is a P-Channel enhancement-mode MOSFET from Vishay Dale, designed for high-efficiency power management applications. It offers a drain-source breakdown voltage of 100V and a continuous drain current of 19A at case temperature. The on-resistance is typically 200mOhm maximum at 11A drain current and 10V gate drive, ensuring low conduction losses.

 

This MOSFET features a gate charge of 61nC and input capacitance of 1400pF, enabling moderate switching speeds suitable for power supply and load switching circuits. The maximum gate threshold voltage is 4V at 250µA, and the device can handle gate-source voltages up to ±20V.

 

Packaged in a surface-mount D2PAK (TO-263-3) with a compact footprint, the IRF9540SPBF is ideal for automated assembly. It operates over a junction temperature range of -55°C to 175°C, with power dissipation ratings of 3.7W at ambient and 150W at case temperature. Typical applications include high-side switching, battery protection, and reverse polarity protection in automotive and industrial systems.
