IRFB3806PBF Description

Short technical summary and product information.

The IRFB3806PBF is an N-Channel power MOSFET from Infineon Technologies, part of the HEXFET family. It features a drain-source voltage (Vdss) of 60V and a continuous drain current of 43A at 25°C case temperature. The device offers a typical on-resistance of 12.6mOhm and a maximum of 15.8mOhm at 25A and 10V gate drive.

Designed for high efficiency synchronous rectification in SMPS, uninterruptible power supplies, and high-speed power switching applications. The MOSFET is characterized for capacitance and avalanche SOA, with enhanced body diode dV/dt and dI/dt capability. It has a maximum gate charge of 30nC at 10V and input capacitance of 1150pF at 50V drain-source.

The device is housed in a TO-220-3 through-hole package (TO-220AB). It operates over a junction temperature range of -55°C to 175°C. Maximum power dissipation is 71W at 25°C case temperature. Thermal resistance junction-to-case is 2.12°C/W and junction-to-ambient is 62°C/W for the TO-220 package.
