It comes in a D2PAK (TO-263) surface-mount package — the large tab is the primary thermal path, so the PCB copper pad under it sets the real-world current limit, not just the 43 A number on the page. ## Conduction loss and gate drive budget At 26 A the conduction loss is 1.4 W per device; double the current to 43 A and the I²R loss climbs to 3.8 W, which is the power dissipation limit at ambient. The gate charge is 91 nC at 10 V — a 100 kHz switching frequency draws 9.1 mA average from the gate driver, well within the capability of a standard driver IC. ## Temperature grade and package reality Junction temperature range is -55°C to 175°C — that is a military-temperature-grade part, usable in avionics, downhole tools, or under-hood automotive where the ambient can hit 125°C and the junction climbs from there. The D2PAK tab needs a soldered copper area on the PCB to pull heat out; a two-layer board with a 1 oz pour under the tab will handle about 20 A continuous before the junction hits 150°C. The 300 W power dissipation at the case is a theoretical ceiling with an infinite heatsink — real designs stay well below that. ## Lifecycle and compliance The HEXFET series has been in production for decades; the die technology is mature and the supply base is stable.","metaTitle":"IRFS38N20DTRLP HEXFET N-Ch MOSFET, 200V, 43A, D2PAK","metaDescription":"IRFS38N20DTRLP N-channel HEXFET MOSFET: 200 V Vdss, 43 A Id, 54 mOhm Rds(on) at 10 V.
