Its key specs for the BOM: 8.9 mOhm max Rds(on) at 25 A with a 10 V gate drive, and a 16 nC gate charge at 4.5 V. The junction temperature range spans -55°C to 175°C, suiting it for industrial power supplies, motor drives, and DC-DC converters where the board sees high ambient heat. ## Rds(on) and gate charge — what they mean for your design The 8.9 mOhm on-resistance at 10 V gate drive is specified at 25 A. The 16 nC gate charge at 4.5 V is listed in the datasheet. The ±20 V gate-source rating gives headroom against ringing on long gate traces, which is common in retrofit panel wiring where the MOSFET sits a few inches from the driver. ## Lifecycle and sourcing — active, no LTB watch needed The IRLU8729-701PBF carries an Active lifecycle status. For a storeroom keeper, that means you can order replenishment without hunting surplus stock. ## Package and mounting — through-hole for serviceability The TO-251-3 through-hole package is a three-lead vertical mount. It suits boards where a technician will hand-solder replacements in the field — no reflow profile needed, just a soldering iron and a desoldering pump.","metaTitle":"IRLU8729-701PBF N-Channel MOSFET, 30V 58A, 8.9mOhm","metaDescription":"IRLU8729-701PBF HEXFET N-Channel MOSFET, 30V, 58A, 8.9mOhm Rds(on) at 10V.
