IRF4905STRLPBF Description

Short technical summary and product information.

The IRF4905STRLPBF is a P-Channel HEXFET power MOSFET from Infineon Technologies, designed for high-efficiency power management applications. It features a drain-to-source breakdown voltage of -55V and a continuous drain current of -42A (package limited at TC=25°C). The device offers ultra-low on-resistance of 20 mΩ maximum at VGS=-10V, enabling reduced conduction losses.

 

This MOSFET provides fast switching performance with typical turn-on delay of 20 ns, rise time of 99 ns, turn-off delay of 51 ns, and fall time of 64 ns. It supports a maximum power dissipation of 170W at TC=25°C and operates over a junction temperature range of -55°C to +150°C. The device is housed in a surface-mount D2PAK (TO-263-3) package, suitable for automated assembly processes.

 

Designed for robust operation, the IRF4905STRLPBF includes avalanche energy ratings of 140 mJ (thermally limited) and 790 mJ (tested), making it suitable for applications requiring high reliability under inductive switching conditions. It is lead-free and RoHS compliant.
