Central Semiconductor Corp. Single Bipolar Transistors MPSA25 TIN/LEAD

The MPSA25 is a NPN Darlington transistor in a TO-92 package, designed for low-current amplification and switching applications. It has a collector-emitter voltage rating of 40 V, a collector-base voltage rating of 40 V, and an emitter-base voltage rating of 10 V. The maximum collector current is 500 mA, and the saturation voltage is 1.50 V at 100 mA collector current. Current gain (hFE) ranges from 10,000 minimum at 100 mA collector current and 30 V collector-emitter bias. The device exhibits a collector-output capacitance of 125 pF and transition frequency of 125 MHz. It is available with tin/lead plating as indicated by the TIN/LEAD suffix.
