X0205MA 2BL2

Scrs Overview

The X0205MA 2BL2 is a silicon-controlled rectifier (SCR) manufactured by STMicroelectronics, belonging to the X02 series. It utilizes a TO-92 through-hole package with three pins. The device features a repetitive peak reverse voltage of 600 V and an average on-state current rating of 1.25 A. It supports a surge current of 25 A. Key gate parameters include a maximum gate trigger current of 200 μA and a maximum gate trigger voltage of 0.8 V. The component operates within a temperature range of -40°C to 125°C.

Scrs Feature Summary

• High sensitivity gate control requiring minimal trigger current for reliable activation
• Robust surge current handling capability suitable for transient protection applications
• Compact through-hole packaging designed for standard PCB mounting techniques

Scrs Applications

• Lighting control circuits
• Motor speed regulation systems

Scrs Procurement Notes

Verify the specific suffix '2BL2' against official STMicroelectronics documentation to confirm exact tape-and-reel specifications or marking codes. Ensure the ordering part number matches the required package variant and thermal characteristics. Cross-reference datasheet revision dates to validate parameter consistency before finalizing procurement orders.

Scrs Selection Notes

Select this component when a low-power SCR with high gate sensitivity is required for through-hole designs. The 600 V blocking voltage provides adequate margin for general AC line applications. Consider the 1.25 A continuous current limit and thermal dissipation requirements in the TO-92 package during circuit design.

Scrs Part Context

This device is part of the X02 family of SCRs from STMicroelectronics. The family focuses on small-signal switching applications where compact size and low gate drive power are critical. These components are engineered for cost-effective integration into consumer electronics and industrial control modules requiring simple thyristor-based switching functions.

Scrs Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 600 V rating, 1.25 A current capacity, and TO-92 pinout configuration.
