HEXFET N-channel 30 V, 140 A — what this D2PAK part delivers
The Infineon IRL3803STRLPBF is a logic-level N-channel HEXFET MOSFET rated for 30 V drain-source breakdown and 140 A continuous drain current at 25°C case temperature. It is housed in a surface-mount D2PAK (TO-263-3) package, making it a fit for high-current power switching on a PCB — motor drives, battery management, DC-DC conversion, and low-voltage power distribution where board space is tight and conduction loss matters. The 6 mOhm maximum on-resistance at 10 V gate drive with 71 A drain current governs I²R loss in the steady-state conduction path.
Gate drive and switching — 4.5 V threshold, 140 nC gate charge
Drive voltage range is 4.5 V to 10 V for achieving the rated on-resistance. Maximum gate threshold is 1 V at 250 µA.
Temperature range and environment — -55°C to 175°C junction
Junction temperature range spans -55°C to 175°C.
Package and mounting — D2PAK (TO-263-3)
Surface-mount D2PAK, three leads plus the tab. The tab is the drain — common to the centre lead in the TO-263 footprint.
Lifecycle and compliance
The IRL3803STRLPBF is listed as Active in production. ROHS3 compliant, so it meets the current exemption framework for EU and global BOMs.
