BCR5FM-12LB#BH0

Overview

The BCR5FM-12LB#BH0 is a standard triac manufactured by Renesas Electronics Corporation. It features a maximum repetitive peak off-state voltage of 600 V and an on-state RMS current rating of 5 A. The device is housed in a TO-220AB (TO-220-3) through-hole package with an isolated flange mount configuration. Key electrical characteristics include a maximum gate trigger voltage of 1.5 V and a maximum gate trigger current of 20 mA. The non-repetitive peak on-state current is rated at 50 A for both 50 Hz and 60 Hz line frequencies.

Feature Summary

• Standard triac configuration designed for general-purpose AC power switching applications
• Robust thermal management capability provided by the isolated flange mount package design
• High surge current handling capacity suitable for inductive load commutation

Applications

• Solid state relays requiring medium power isolation
• AC motor speed control circuits for small appliances
• Lighting dimmer modules for residential or commercial use

Procurement Notes

Verify the specific suffix #BH0 against official Renesas documentation to confirm exact marking and packaging details, as suffixes often denote tape-and-reel quantities or specific labeling variations distinct from bulk tube packaging. Confirm RoHS compliance status directly with the manufacturer datasheet, as environmental declarations can vary by production batch and region. Ensure the supplier provides valid traceability records for semiconductor components.

Selection Notes

Select this component when a 600 V blocking voltage and 5 A continuous current are required in a cost-effective through-hole format. The TO-220AB package allows for direct heatsinking via the isolated tab, simplifying thermal design compared to insulated alternatives. Verify that the gate trigger requirements of the driving circuit align with the specified 1.5 V and 20 mA limits to ensure reliable turn-on under varying temperature conditions.

Part Context

This part belongs to the BCR5 series of medium-power triacs produced by Renesas Electronics. The series is widely utilized in household appliances and industrial controls where reliable AC switching is necessary. The BCR5FM variant specifically denotes the 600 V/5 A performance class within the broader family, sharing pinouts and mechanical dimensions with other ratings in the lineup for design flexibility.

Replacement Considerations

Direct replacements include the BCR5KM-12L and BCR5AM-12LB#B01, which share identical 600 V/5 A specifications and TO-220-3 packaging. When substituting, verify that the replacement device meets the same gate trigger current and voltage thresholds to maintain compatibility with existing drive circuitry without modification.
