2SD2562

Overview

The 2SD2562 is a Silicon NPN Triple Diffused Planar Transistor manufactured by Sanken Electric. It operates with a collector-emitter voltage of 150V and a continuous collector current of 15A. The device features a high DC current gain (hFE) of at least 5000 and a transition frequency (fT) of 70MHz. It is housed in the FM100 (TO-3PF) package, which supports a maximum power dissipation of 85W at 25°C case temperature. The transistor serves as the complement to the 2SB1649 PNP type.
