BCR3FM-12LB#BB0

Overview

The BCR3FM-12LB#BB0 is a standard triac manufactured by Renesas Electronics, designed for general-purpose AC power control applications. It features a maximum repetitive peak off-state voltage of 600V and an RMS on-state current rating of 3A. The device operates within a junction temperature range of -40°C to +150°C. Key electrical characteristics include a maximum gate trigger voltage of 1.5V and a maximum gate trigger current of 20mA. It supports a non-repetitive surge current of 30A at 60Hz. The component is housed in a TO-220FP (Full Pack) through-hole package.

Feature Summary

• Standard triac configuration suitable for general AC switching tasks
• Robust thermal performance with a high junction temperature capability up to 150°C
• High surge current handling capacity for inductive load protection
• Through-hole mounting for secure mechanical attachment

Applications

• General purpose AC motor speed control
• Lighting dimmer circuits
• Heater control systems

Procurement Notes

Verify the obsolete status and end-of-life notification prior to procurement. Confirm availability through authorized distributors as stock may be limited. Ensure the specific suffix #BB0 matches the required packaging format. Check for any product change notifications that might affect pinout or specifications. Validate RoHS compliance documentation for regulatory requirements.

Selection Notes

Select this component when a 600V blocking voltage and 3A continuous current are sufficient for the load. Consider the TO-220FP package for adequate heat dissipation without active cooling in moderate duty cycles. Verify that the gate trigger parameters align with the driving circuit capabilities. Evaluate alternative packages if PCB space constraints differ from through-hole requirements.

Part Context

This part belongs to the BCR series of thyristors from Renesas Electronics, formerly NEC Electronics. The series is known for planar passivation technology and insulated types suitable for various industrial applications. The BCR3FM variant specifically targets medium-power switching needs with reliable latching characteristics.
