2SA2151

Single Bipolar Transistors Overview

The Sanken Electric 2SA2151 is a PNP silicon power transistor housed in a TO-3P package. It features a collector-emitter voltage (VCEO) of -200 V and a maximum collector current (IC) of -15 A. The device supports a collector power dissipation (PC) of 160 W at 25°C ambient temperature, with a junction temperature rating up to 150°C. DC current transfer ratio (hFE) ranges from 50 to 180 depending on the specific sub-range ordered. The component utilizes a wafer-thinner technique to reduce thermal resistance and improve avalanche breakdown ratings.

Single Bipolar Transistors Procurement Notes

Verify the hFE range specification when ordering, as the part number alone does not define the gain band. Specify Range O (50–100), Range P (70–140), or Range Y (90–180). If no range is specified, fulfillment depends on availability. Confirm RoHS compliance status regarding high-temperature solder exemption. Ensure storage conditions adhere to standard temperature and humidity limits to prevent lead rusting.

Single Bipolar Transistors Selection Notes

Select this component for multichannel AV amplifier applications or parallel connection setups in professional audio systems. Consider the complementary 2SC6011 NPN transistor for matched pairs. Evaluate the recommended output driver 2SA1668 if system compatibility requires it. Verify that the -200 V rating meets circuit requirements, noting that -230 V versions exist for specific PA applications.
