Diotec Semiconductor Single Bipolar Transistors 2SC3851

The 2SC3851 is an NPN bipolar transistor designed for high-current power amplification and driver circuits. It is packaged in an ITO-220AB case with an isolated heat flange, weighing approximately 2.2 g. The device has a collector-emitter voltage rating of 60 V, a continuous collector current of 4 A, and a maximum power dissipation of 25 W at 25°C. The junction temperature ranges up to 150°C, and the case material meets UL 94 V-0. It complies with RoHS, REACH, and Conflict Minerals directives. The -Q and -AQ suffix variants are AEC-Q101 compliant and qualified, respectively. Typical thermal resistance from junction to case is 4 K/W, and the gain-bandwidth product is 15 MHz.
