Product details

Thermal and mounting considerations

Maximum power dissipation is 500 W at case temperature, but real-world dissipation depends on the heatsink and airflow. The junction temperature range of -55°C to 150°C covers industrial and automotive under-hood environments. The through-hole TO-247-3 package (PG-TO247-3) is designed for screw-mount or clip-mount to a heatsink; the exposed metal tab is the drain. Mounting torque should follow the manufacturer's recommendation to avoid package stress.

Active lifecycle — no obsolescence concern

ROHS3 compliant. For new designs or spares, this part is a safe choice without last-time-buy risk.
