It is built for low-voltage, high-current switching applications such as DC-DC converters, motor drives, and power distribution switches. The 3.1 mOhm typical on-resistance at 10 V gate drive keeps conduction losses low in a 76 A load path, while the 175°C maximum junction temperature gives headroom for thermally constrained environments like automotive engine bays or industrial enclosures. Maximum Rds(on) is 3.1 mOhm at 76 A and 10 V gate drive. Gate charge is 99 nC at 10 V. ## Package and mounting — DPAK for automated assembly The DPAK (TO-252-3) footprint is a common surface-mount power package with a tab for heatsinking. ## Lifecycle and compliance — active and RoHS3 compliant It is ROHS3 compliant. Verify REACH or UL documentation with your compliance team if required for end-equipment certification.","metaTitle":"AUIRFR8403TRL MOSFET N-CH 40V 100A DPAK, 3.1 mOhm","metaDescription":"AUIRFR8403TRL N-Channel MOSFET, 40V Vdss, 100A Id, 3.1mOhm Rds(on) at 10V.
