Its key distinguishing feature is a maximum on-resistance of 4.5 mOhm at 40 A with a 10 V gate drive, which keeps conduction losses low in high-current switching applications. The device is built for power conversion, motor drives, battery management, and DC-DC converter stages where a TO220AB package is preferred for heatsinking and board-level serviceability. ## Gate drive and threshold — why the 2.25 V Vgs(th) matters With a maximum gate threshold voltage of 2.25 V at 250 µA, the IRL8114PBF is a logic-level MOSFET. It can be driven directly from a microcontroller output without a separate gate-driver stage, simplifying the BOM in low-voltage control circuits. ## Thermal and package considerations Rated for a junction temperature range of -55°C to 175°C, the IRL8114PBF handles high ambient temperatures common in motor-drive cabinets, power-supply enclosures, and under-hood automotive environments. The TO220AB package allows direct mounting to a heatsink with a single screw, and the through-hole leads suit wave-solder assembly or hand-rework in prototype and repair scenarios. The 115 W power dissipation figure assumes proper heatsinking — derate according to the thermal resistance in the datasheet. ## Switching performance and gate charge A maximum gate charge of 29 nC at 4.5 V means the IRL8114PBF switches efficiently even with modest gate-drive current. This low Qg reduces driver losses and allows higher switching frequencies in synchronous rectifiers and buck converters. The 0.0027 µF input capacitance (Ciss) is consistent with a device optimized for low Rds(on) rather than ultra-fast switching — expect clean waveforms up to several hundred kHz with appropriate layout. ## Lifecycle and sourcing The IRL8114PBF carries an Active lifecycle status — no last-time-buy or end-of-life notice is in effect. It remains a current-production part suitable for new designs and BOM freeze.","metaTitle":"IRL8114PBF MOSFET N-CH 30V 90A TO220AB, 4.5 mOhm Rds(on)","metaDescription":"IRL8114PBF N-channel HEXFET MOSFET, 30V, 90A, 4.5 mOhm Rds(on) at 10V, TO220AB.
