TIP31AG

Single Bipolar Transistors Overview

The TIP31AG is an NPN silicon power transistor from the onsemi TIP31G series, housed in a TO-220 package. It features a collector-emitter voltage (VCEO) of 60 Vdc and a continuous collector current (IC) of 3.0 Adc. The device supports a peak collector current of 5.0 Adc and dissipates up to 40 W at a case temperature of 25°C. Key electrical characteristics include a DC current gain (hFE) ranging from 10 to 50 at IC = 1.0 Adc, a collector-emitter saturation voltage of 1.2 Vdc max, and a gain-bandwidth product (fT) of 3.0 MHz. Operating temperatures range from -65°C to +150°C.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix 'AG' against the manufacturer's current datasheet to confirm availability status. The documentation indicates that certain variants within the TIP31G family are discontinued or not recommended for new designs; ensure this specific part number is active before procurement planning.

Single Bipolar Transistors Selection Notes

Select the TIP31AG when a 60 V collector-emitter rating is required, distinguishing it from the 40 V (TIP31G), 80 V (TIP31BG), and 100 V (TIP31CG) variants. Ensure thermal management design accounts for the 40 W dissipation limit at 25°C case temperature and the derating curve provided in the datasheet.

Single Bipolar Transistors Part Context

This component belongs to the complementary TIP31/TIP32 series of silicon power transistors manufactured by onsemi. The series includes NPN (TIP31x) and PNP (TIP32x) devices with varying voltage ratings. The TIP31AG specifically denotes the NPN variant with a 60 V breakdown voltage.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes within the same voltage class include the TIP31A from other manufacturers, provided they meet the 60 V VCEO and 3 A IC requirements. Verify pinout compatibility (Base, Collector, Emitter) and package dimensions (TO-220) before substitution.
