2SB566KC-E

Single Bipolar Transistors Overview

The 2SB566KC-E is a silicon PNP triple diffused transistor manufactured by Renesas Electronics Corporation, formerly Hitachi. It is designed for low-frequency power amplifier applications and serves as a complementary pair component to the 2SD476 series. The device features a maximum collector current of 4 A and a maximum power dissipation of 40 W at 25°C ambient temperature. It operates with a minimum DC current gain (hFE) of 60 and supports junction temperatures up to 150 °C. The component utilizes a TO-220AB package configuration.

Single Bipolar Transistors Feature Summary

• Triple diffused silicon PNP construction for robust power handling
• Designed specifically for low-frequency power amplifier circuits
• Complementary pairing capability with 2SD476 series NPN transistors

Single Bipolar Transistors Applications

• Low frequency power amplifiers
• Power switching applications requiring complementary pairs

Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'KC-E' against official Renesas documentation to confirm exact binning or environmental compliance status, as standard datasheets may list broader variants like 2SB566(K). Ensure the TO-220AB package footprint matches your PCB design requirements. Confirm lead availability through authorized distributors, as older discrete components may have limited stock or end-of-life implications.

Single Bipolar Transistors Selection Notes

Select this component when designing low-frequency power amplification stages that require a high-current PNP switch. Ensure the thermal management solution can handle the 40 W dissipation rating. Verify compatibility with the intended complementary NPN device, such as the 2SD476 series, for balanced circuit performance. Check that the operating voltage and current limits align with the specific application demands.

Single Bipolar Transistors Part Context

This transistor belongs to the legacy Hitachi discrete semiconductor portfolio now managed by Renesas Electronics. It is part of a family of power transistors historically used in audio and industrial power supply designs. The SH7266 microcontroller and other listed items are unrelated digital or power ICs from different product lines within the same manufacturer's catalog.

Single Bipolar Transistors Replacement Considerations

Consult official Renesas documentation for direct substitutes. Generic replacements must match the PNP polarity, 4 A current rating, 40 W power dissipation, and TO-220AB package. Verify hFE minimums and voltage ratings before substitution.
