2SB1274R-SA

Single Bipolar Transistors Overview

The Sanyo 2SB1274R-SA is a PNP silicon epitaxial planar transistor designed for low-frequency power amplifier applications. It features a collector-emitter breakdown voltage of 60V and a maximum continuous collector current of 3A. The device utilizes an MBIT process to achieve wide safe operating area (ASO) characteristics and low saturation voltage. It is housed in a TO-220F plastic package, which facilitates mounting without the need for mica insulators.

Single Bipolar Transistors Feature Summary

• Wide Safe Operating Area (ASO) enabled by MBIT process adoption
• Low collector-to-emitter saturation voltage for efficient power handling
• Micaless package design simplifies thermal interface mounting

Single Bipolar Transistors Applications

• General low-frequency power amplifiers
• Audio output stages
• Power switching circuits

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'SA' against the manufacturer's official datasheet to confirm pinout configuration and packaging variations. Ensure the component source matches Sanyo Semicon Device specifications. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring robust PNP power switching or amplification at 60V. The TO-220F package offers direct heatsink mounting capabilities. Compare its saturation voltage and ASO limits against circuit requirements to ensure adequate performance margins under load conditions.

Single Bipolar Transistors Part Context

This transistor belongs to the Sanyo PNP power transistor family, often paired with complementary NPN devices like the 2SC series for push-pull amplifier configurations. It is engineered for reliability in consumer audio and industrial power control systems where high current handling and thermal stability are critical.

Single Bipolar Transistors Replacement Considerations

The 2SB1510 is a documented similar part from Sanyo with comparable 60V/3A ratings. Other potential substitutes include the Toshiba 2SA1362 or generic TO-220 PNP transistors meeting the 60V/3A specification, provided pinouts and thermal characteristics align.
