It comes in a TO-262-3 (I²Pak) through-hole package with long leads, rated for a junction temperature range of -55°C to 150°C. The 280 mOhm maximum on-resistance at 10 A, 10 V gate drive sets the conduction loss anchor for heatsink design. ROHS3 compliant. For a BOM freeze or a production ramp, this part does not trigger last-time-buy urgency. ## Mounting and thermal — through-hole with a tab The TO-262-3 (I²Pak) package is a through-hole variant with long leads, designed for mounting on a PCB with the metal tab either soldered to a copper island or clamped to a separate heatsink. The 160 W maximum power dissipation at case temperature assumes the tab is held at 25°C — in practice, a forced-air heatsink with thermal resistance below 1°C/W is needed to stay inside the 150°C junction limit at full rated current. The PG-TO262-3-1 supplier package code matches the standard I²Pak footprint.","metaTitle":"Infineon SPI16N50C3 CoolMOS™ N-Channel MOSFET, 500V 16A","metaDescription":"Infineon SPI16N50C3 CoolMOS™ N-Channel MOSFET: 500V Vdss, 16A continuous drain, 280mOhm Rds(on) at 10V.
