The device is housed in a TO-262-3 (I²Pak) through-hole package (PG-TO262-3-1), which supports the 156 W power dissipation rating when mounted to an adequate heatsink. ## Conduction and switching losses at the BOM level The 280 mOhm Rds(on) at 10 V gate drive sets the conduction loss floor: at 9.4 A drain current the voltage drop is about 2.6 V, and the I²R loss reaches roughly 25 W — well within the 156 W dissipation limit when the case is held at 25°C. The 1600 pF input capacitance at 25 V drain-source bias confirms the driver sees a moderate capacitive load. ## Temperature range and mounting constraints The through-hole TO-262-3 package with long leads (I²Pak) requires a heatsink for continuous operation above a few amps — the 156 W dissipation rating assumes the case is held at 25°C, which in practice means a thermal interface to a heatsink with adequate airflow. The PG-TO262-3-1 supplier package code matches the standard I²Pak footprint. ## Active production and compliance It is ROHS3 compliant, which simplifies compliance for EU and global markets. No official second-source or pin-compatible alternate is listed in the ledger; for dual-sourcing, a parametric search across CoolMOS 650 V / 15 A / TO-262 devices would be the next step.","metaTitle":"Infineon SPI15N65C3 CoolMOS N-Channel MOSFET, 650 V, 15 A","metaDescription":"Infineon SPI15N65C3 CoolMOS N-channel MOSFET, 650 V Vdss, 15 A continuous drain, 280 mOhm Rds(on) at 10 V.
