IRL3803PBF

The IRL3803PBF is a logic-level N-Channel MOSFET manufactured by Infineon Technologies. It is designed for high-efficiency power switching applications and offers a drain-source voltage (Vdss) of 30V and a continuous drain current (Id) of 140A at Tc=25°C with a 10V gate drive. The device features an ultra-low on-resistance of 6 mΩ maximum at 10V (71A) and 9 mΩ at 4.5V (59A), enabling minimal conduction losses. The logic-level gate threshold voltage (Vgs(th)) is 1.0V minimum, allowing direct drive from 3.3V or 5V logic circuits. The MOSFET also supports fast switching with a typical total gate charge of 140 nC and input capacitance of 5000 pF. It is fully avalanche rated with a single pulse avalanche energy of 610 mJ and has a rugged design for robust operation. The device is packaged in a TO-220-3 (TO-220AB) through-hole package with a junction-to-case thermal resistance of 0.75°C/W and a maximum power dissipation of 200W. The operating junction temperature range is -55°C to 175°C, making it suitable for demanding industrial and automotive environments. The IRL3803PBF is RoHS3 compliant, lead-free, and has an MSL rating of 1 (unlimited). Typical applications include DC-DC converters, synchronous rectification, motor control, and high-current load switching.
