Silicon NPN Triple Diffused Planar TransistorDarlingtonNPN
. The 2SD2401 is a PNP silicon power transistor made by Sanken Electric. It is designed for linear and switching applications in the 200V, 2A range. The transistor features a low collector-emitter saturation voltage VCE(sat) of 0.3V, a low collector-base breakdown voltage V(BR)CBO of -250V, and a high gain hFE of 60. It is suitable for use as an audio power amplifier, switch, chopper, and speed control circuit. It can also be used in high-speed switching circuits requiring a low collector-emitter saturation voltage and fast switching time. It is also suitable for low-voltage applications, such as in portable battery-powered circuits. (For reference only)
