X0405MH

Scrs Overview

The X0405MH is a Silicon Controlled Rectifier (SCR) from STMicroelectronics, rated for 600 V blocking voltage and 4 A average on-state current. It features a sensitive gate with a maximum trigger voltage of 800 mV and a holding current of 5 mA. The device supports a peak non-repetitive surge current of 33 A and operates at junction temperatures up to 125°C. Housed in an IPAK through-hole package, it provides robust performance for power control applications requiring reliable switching capabilities.

Scrs Feature Summary

• Sensitive gate design enables low-power triggering requirements
• High surge current capability ensures resilience during transient events
• Compact IPAK through-hole package facilitates easy integration

Scrs Applications

• Lighting dimmers
• Motor speed controls
• Heating control systems

Scrs Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging configuration, such as tube or reel options, as these may vary by distributor. Ensure that the requested quantity aligns with the manufacturer's minimum order requirements and lead times. Cross-reference the datasheet parameters against your circuit design specifications to guarantee compatibility with voltage and current ratings before finalizing procurement.

Scrs Selection Notes

Select this component when a 600 V SCR with 4 A continuous current capacity is required. The sensitive gate characteristic makes it suitable for circuits where low gate drive power is essential. Consider the IPAK package for through-hole mounting needs and verify that the 125°C maximum junction temperature meets the thermal management constraints of the intended application environment.

Scrs Part Context

This part belongs to the STMicroelectronics X04 series of silicon controlled rectifiers. The series is designed for general-purpose power control applications, offering a balance of high current handling and compact form factor. The X0405MH specifically targets markets requiring reliable thyristor solutions in standard through-hole configurations for industrial and consumer electronics.

Scrs Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 600 V rating, 4 A current capacity, and IPAK package dimensions. Verify gate sensitivity and thermal characteristics to maintain system performance.
