MCR69-003

Overview

The MCR69-003 is a Silicon Controlled Rectifier (SCR) from onsemi, designed for overvoltage protection in crowbar circuits. It features a reverse blocking thyristor structure with a peak repetitive off-state voltage of 100V and an RMS on-state current rating of 25A. The device supports a peak non-repetitive surge current of 300A at 60Hz. Packaged in TO-220AB, it provides robust performance for industrial power applications requiring reliable crowbar protection mechanisms.

Feature Summary

Designed specifically for overvoltage protection within crowbar circuit configurations
Reverse blocking thyristor structure ensures reliable operation under high voltage conditions

Applications

Crowbar circuit implementations for power supply protection
Overvoltage protection systems in industrial equipment
Silicon controlled rectifier based safety shutdown mechanisms

Procurement Notes

Verify the specific part number against official onsemi documentation to confirm availability status, as lifecycle information may vary by region or distributor. Ensure that the TO-220AB package dimensions match your PCB layout requirements. Cross-reference thermal characteristics with your system's heat dissipation capabilities to guarantee safe operating temperatures during surge events.

Selection Notes

Select this component when a 100V voltage rating and 25A continuous current capacity are required for crowbar applications. Consider the 300A surge capability for transient protection scenarios. Evaluate the TO-220AB package for mounting constraints and thermal management needs compared to alternative SCR packages offering different current ratings or voltage thresholds.
