2SD16400Q

Single Bipolar Transistors Overview

The Panasonic 2SD1640Q is a silicon NPN epitaxial planar type Darlington transistor designed for low-frequency output amplification. It features a high forward current transfer ratio (hFE) and large peak collector current capability. The device operates with a maximum collector-emitter voltage of 100 V, a continuous collector current of 2 A, and a peak collector current of 3 A. Power dissipation reaches 1.2 W at 25°C ambient temperature. The component is housed in a TO-126B-A1 package.
