The 4300 pF input capacitance (Ciss) at 25 V drain-source gives a rough Miller-plateau charge that a standard totem-pole gate driver handles without a pre-driver stage. The drive voltage is specified at both 5 V and 10 V, so logic-level gate signals from a 5 V MCU or PWM controller can switch the MOSFET into its minimum Rds(on) region. It is ROHS3 compliant. No official successor or pin-compatible cross-reference is listed on the record, so the BOM line depends on this exact order code for the AEC-Q101 qualification and the D2PAK footprint.","metaTitle":"STB120N4LF6 N-Channel MOSFET, 40V 80A, AEC-Q101, D2PAK","metaDescription":"STB120N4LF6 N-Channel MOSFET, 40V drain-source, 80A continuous drain, 4mOhm Rds(on) at 10V.
