X0202MN 5BA4

Scrs Overview

The X0202MN 5BA4 is a silicon controlled rectifier (SCR) from STMicroelectronics, packaged in a surface-mount SOT-223 (TO-261AA) configuration. It features a forward blocking voltage of 600V and an on-state current rating of 1.25A. The device is characterized by a holding current of 5mA maximum and supports junction temperatures up to 125°C. Designed for sensitive gate triggering, it requires minimal gate current for activation, making it suitable for applications with limited drive capability.

Scrs Feature Summary

• Optimized for reduced power losses and high reliability in harsh environments
• Highly sensitive triggering levels suitable for limited gate current applications
• Surface mount package design for automated assembly

Scrs Applications

• On/off switching functions where topology does not offer high current for gate triggering
• Applications requiring reduced power losses due to optimized forward voltage drop
• Circuits demanding high reliability in harsh environmental conditions

Scrs Procurement Notes

Verify the specific ordering suffix '5BA4' against the official STMicroelectronics datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the SOT-223 footprint matches your PCB design requirements. Cross-reference the 600V/1.25A ratings with your circuit's peak load and voltage stress to ensure adequate safety margins before finalizing procurement.

Scrs Selection Notes

Select this component when the application requires a surface-mount SCR with low gate trigger current requirements. It is appropriate for designs where space constraints favor the SOT-223 package over through-hole alternatives. Ensure the system can handle the 1.25A on-state current and that the 600V blocking voltage exceeds the maximum transient voltages present in the circuit.

Scrs Part Context

This part belongs to the X02 SCR series, which is engineered for sensitive gate operation. The series is designed to address scenarios where available gate current is limited, allowing for efficient triggering without complex driver circuits. The X0202MN variant specifically utilizes the TO-261AA/SOT-223 form factor to integrate these performance characteristics into compact surface-mount assemblies.

Scrs Replacement Considerations

Consult official STMicroelectronics substitution guides for compatible SCRs within the same voltage and current class. Verify pinout compatibility and thermal resistance characteristics if replacing with devices from other manufacturers. Ensure any substitute maintains the sensitive gate requirement and SOT-223 package dimensions.
