Panasonic 2SC4161L

NPN silicon transistor for switching regulator applications, rated for 400 V collector-to-emitter voltage and 7 A continuous collector current, housed in a TO-220ML package with dimensions of 10.0 mm × 6.5 mm × 4.5 mm and a three-pin configuration. Features high breakdown voltage, high-speed switching with a typical turn-off time of 0.1 µs, wide safe operating area, and operates up to 150 °C junction temperature. Rated for a collector dissipation of 30 W at Tc = 25 °C, with a gain-bandwidth product of 20 MHz. Complies with SANYO's MBIT process and micaless mounting design. No explicit rating for the "L" variant is provided; summary reflects the base 2SC4161 series.
