2SD2118TLR

Single Bipolar Transistors Overview

The ROHM 2SD2118TLR is an NPN silicon epitaxial planar transistor designed for strobe flash applications. It features a low collector-emitter saturation voltage of 0.25V typical at IC/IB = 4A/0.1A. The device supports a DC collector current of 5A and a pulse current of 10A, with a collector-emitter breakdown voltage of 20V. Power dissipation reaches 1W on a glass epoxy board or 10W with case mounting. It utilizes the CPT3 (TO-252) surface-mount package.
