BCR5AS-12B#B01

Overview

The BCR5AS-12B#B01 is a standard Triac manufactured by Renesas Electronics Corporation, designed for general-purpose AC power control applications. This component features a 600 V blocking voltage and an RMS on-state current rating of 5 A. It is housed in a TO-220-3 through-hole package, facilitating robust thermal management and mechanical stability in industrial environments. Key electrical specifications include a maximum gate trigger voltage of 1.5 V and a maximum gate trigger current of 20 mA. The device supports a non-repetitive surge current of 50 A at 60 Hz, ensuring resilience against transient load conditions.

Feature Summary

• Standard Triac configuration for reliable AC switching
• Through-hole mounting for secure PCB integration
• High surge current capability for transient protection

Applications

• General-purpose AC motor speed control
• Solid-state relay (SSR) output stages
• Resistive load switching in industrial equipment

Procurement Notes

Verify the specific suffix #B01 to confirm packaging and tape-and-reel specifications, as these details are critical for automated assembly processes. Confirm RoHS compliance status with the manufacturer, as environmental declarations may vary by production batch or region. Ensure that the procurement channel provides traceability documentation consistent with Renesas Electronics quality standards for automotive or industrial-grade components.

Selection Notes

Select this component when a 5 A RMS current capacity and 600 V voltage rating align with the circuit requirements. The TO-220-3 package necessitates adequate heatsinking considerations for continuous operation near the rated current limit. Evaluate the gate trigger characteristics against the driving circuit's output capabilities to ensure reliable turn-on under all operating temperatures and load conditions.

Part Context

This part belongs to the BCR series of Triacs from Renesas Electronics, which are widely used in power electronics for controlling alternating current. The series offers various current ratings and voltage classes to suit different power levels. The BCR5AS variant specifically targets applications requiring moderate power handling with standard switching characteristics, bridging the gap between lower-current logic-controlled devices and higher-power industrial thyristors.

Replacement Considerations

Direct replacements must match the 600 V / 5 A specification and TO-220-3 footprint. Verify pinout compatibility (MT1, MT2, Gate) before substitution. Cross-reference with other Renesas BCR series parts or equivalent industry-standard Triacs, ensuring identical thermal resistance and gate trigger parameters to maintain circuit performance without redesign.
