Overview
The SMUN2111T1G is a PNP Bias Resistor Transistor (BRT) from onsemi, integrating a single transistor with a monolithic bias network consisting of two resistors. It operates within a collector-emitter voltage range of 50 Vdc and supports continuous collector currents up to 100 mAdc. The device features an input forward voltage rating of 40 Vdc and reverse voltage of 10 Vdc. Electrical characteristics include a minimum DC current gain (hFE) of 35 at 5.0 mA and 10 V, with a typical value of 60. The integrated resistor ratio (R1/R2) is typically 1.0, with R1 being 10 kOhms. Thermal dissipation in the SC-59 package reaches 230 mW at 25°C ambient temperature.
