Overview
The STA460C is an NPN Darlington power transistor manufactured by Sanken Electric. It features a collector-emitter voltage (VCEO) of 60 V and a continuous collector current (IC) rating of ±6 A at 25°C, with a peak pulse current (ICP) of ±10 A. The device includes a built-in avalanche diode for inductive load protection. Key electrical characteristics include a DC current gain (hFE) ranging from 700 to 3000 at IC=1A, and a saturated collector-emitter voltage (VCE(sat)) of 0.15 V maximum at IC=1.5A. The maximum junction temperature (Tj) is 150°C, and the total power dissipation (PT) reaches 18 W with a case temperature of 25°C.
