CR8FM-12B#BH0

Overview

The CR8FM-12B#BH0 is a silicon-controlled rectifier (SCR) manufactured by Renesas Electronics Corporation, designed for medium power applications. It features a maximum repetitive peak off-state voltage of 600 V and an average on-state current rating of 8 A. The device utilizes a TO-220FPA package with three leads. Key electrical characteristics include a maximum gate trigger voltage of 1 V and a maximum gate trigger current of 15 mA. The on-state voltage drop is specified at a maximum of 1.4 V. This component is lead-free and suitable for use in switch-mode power supplies and power tools.

Feature Summary

• High-voltage blocking capability rated at 600 V for robust performance in demanding circuits
• Medium-power handling with an 8 A average on-state current rating
• Low gate trigger requirements ensuring efficient control signal interfacing
• Standard through-hole packaging facilitating easy integration into existing board layouts

Applications

• Switch-mode power supplies (SMPS)
• Power tool motor control
• General purpose thyristor switching circuits

Procurement Notes

Verify the specific suffix #BH0 to ensure correct package type and pin configuration compatibility with your design. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for any recent product change notifications or end-of-life notices from the manufacturer to ensure long-term supply availability for production runs.

Selection Notes

Select this component when a 600 V blocking voltage and 8 A continuous current capacity are required in a standard through-hole format. Consider the thermal resistance and junction temperature limits relative to your heat sinking strategy. Ensure the gate trigger parameters align with your driving circuit's output capabilities to guarantee reliable turn-on under all operating conditions.

Part Context

This SCR belongs to the CR8FM series of thyristors intended for medium power applications. It serves as a replacement or alternative for similar devices in industrial and consumer electronics. The part is distinct from TRIACs like the BCR5FM series due to its unidirectional current flow characteristic. It is commonly used where robust AC power control is needed in compact form factors.

Replacement Considerations

The CR8PM-12B#B00 is listed as a replacement product within the same family. Verify package dimensions and thermal characteristics when substituting. Ensure that the electrical ratings of the alternative part meet or exceed the original design requirements.
