For a 100 kHz switching frequency, the average gate drive current needed is 18 mA — well within the capability of a standard MOSFET driver. The ±20 V maximum gate-source rating provides margin for gate-drive transients in noisy environments. ## Temperature range and power dissipation Maximum power dissipation is 170 W at case temperature, derated above that point per the datasheet curve. The TO-262 through-hole package (I²Pak) provides a low thermal resistance path to a heatsink via the exposed metal tab. ## Lifecycle and compliance It is ROHS3 compliant, and the TO-262 package is standard through-hole for automated or manual assembly.","metaTitle":"IRF4905LPBF P-Channel MOSFET, 55V 42A, 20mOhm Rds(on)","metaDescription":"IRF4905LPBF P-Channel HEXFET MOSFET, 55V drain-source, 42A continuous drain, 20mOhm Rds(on) at 10V.
