NSVMMUN2114LT3G

Overview

The NSVMMUN2114LT3G is a discontinued Bias Resistor Transistor (BRT) manufactured by onsemi. It integrates a single PNP transistor with a monolithic bias network consisting of a series base resistor and a base-emitter resistor within an SOT-23 package. The device features a collector-emitter voltage (VCEO) of 50 Vdc, continuous collector current of 100 mAdc, and power dissipation of 246 mW at 25°C. Electrical characteristics include a minimum DC current gain (hFE) of 80, typical input resistance of 10 kOhms, and a resistor ratio of 0.21. It operates within a junction temperature range of -55°C to +150°C.
