The 2N5686G is an NPN high-current silicon power transistor designed for use in high-power amplifier and switching circuit applications. It features a high continuous collector current capability of 50 Amperes and a collector-emitter voltage rating of 80 Vdc. The transistor provides a DC current gain (hFE) ranging from 15 to 60 at a collector current of 25 Adc, coupled with a low collector-emitter saturation voltage of 1.0 Vdc maximum under the same conditions. With a total power dissipation of 300 W, its robust characteristics make it ideal for demanding power amplification and switching circuits.
