What this 40V N-channel HEXFET is built for
The Infineon IRLB3034PBF is a 40V N-channel MOSFET from the HEXFET series, rated for 195A continuous drain current at 25°C case temperature. Its 1.7 mOhm maximum on-resistance at 10V gate drive keeps conduction losses low in high-current paths like battery isolation, motor drives, and DC-DC converter output stages. The TO-220AB through-hole package suits point-of-load power stages where a heatsink is practical and board-space is not the primary constraint.
Thermal and mechanical fit
The TO-220AB package dissipates up to 375W at the case. Junction temperature range is -55°C to 175°C.
