The MPSA28 is a silicon NPN Darlington transistor designed for general purpose amplification and switching applications in a TO-92 package. It has a collector-emitter voltage rating of 80 V, a continuous collector current of 800 mA, and a total device dissipation of 625 mW at 25°C, derating at 5 mW/°C above that temperature. The junction temperature range is -55°C to +150°C, with a thermal resistance from junction to ambient of 200°C/W. The transistor exhibits a minimum DC current gain of 10,000 at collector currents of 10 mA and 100 mA, a collector-emitter saturation voltage of up to 1.5 V at 100 mA collector current, and a base-emitter on voltage of up to 2.0 V. The current gain-bandwidth product is 125 MHz, and the output capacitance is 8 pF. The device complies with standard bipolar transistor operating limits and is suited for low-power signal and switching circuits.
