STFW3N150 ST Power MOSFET

The STFW3N150 is an N-channel PowerMOSFET using STMicroelectronics' PowerMESH technology, featuring a 1500V drain-source voltage (VDS), 2.5A continuous drain current, and a maximum RDS(on) of 9Ω in an insulated TO-3PF package with 63W power dissipation . For selection, verify the ±30V gate-source voltage rating, high-speed switching capability with minimized intrinsic capacitances and gate charge, 100% avalanche tested with 450mJ single pulse avalanche energy rating, and operating junction temperature range from -55°C to +150°C . The TO-3PF package offers 3.5kV RMS insulation withstand voltage from leads to external heatsink, simplifying assembly without insulating washers. Applications include high-voltage switching power supplies, power factor correction circuits, off-line UPS systems, capacitor discharge circuits, induction heating systems, and any high-voltage DC-DC converter requiring a rugged, high-voltage power switch with excellent thermal performance.
