2SB1237TV2Q

Single Bipolar Transistors Overview

The 2SB1237TV2Q is a PNP silicon epitaxial planar transistor manufactured by Rohm Semiconductor. It features a collector-emitter breakdown voltage of -32V and a maximum continuous collector current of -1A. The device has a power dissipation rating of 1W at 25°C ambient temperature, with a junction temperature limit of 150°C. Electrical characteristics include a minimum DC current gain (hFE) of 120 at -100mA/-3V, a typical saturation voltage of -0.2V at -500mA/-50mA, and a transition frequency of 150MHz. It utilizes an ATV through-hole package.
