2SD21840RA

Single Bipolar Transistors Overview

The Panasonic 2SD2184RA is a silicon NPN epitaxial planar transistor designed for low-frequency output amplification. It features a high collector-emitter voltage of 150 V and a low collector-emitter saturation voltage of 0.30 V maximum at 500 mA. The device supports a continuous collector current of 1 A with a peak rating of 1.5 A, dissipating up to 1 W of power. It utilizes the MT-2-A1 package and offers a forward current transfer ratio (hFE) ranging from 120 to 340 depending on the rank.
