BTW68-200RG

Scrs Overview

The BTW68-200RG is a Silicon Controlled Rectifier (SCR) manufactured by STMicroelectronics, belonging to the BTW68 series. It features a rated repetitive off-state voltage (VDRM) of 200 V and a holding current maximum of 75 mA. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-3P-3 through-hole package. Key electrical parameters include a forward voltage of 2.1 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 50 mA. The non-repetitive on-state current capacity is 420 A, with an off-state leakage current of 20 µA at VDRM.

Scrs Feature Summary

• Monolithic construction in a robust TO-3P-3 through-hole package designed for high-power applications.
• Capable of handling significant non-repetitive surge currents up to 420 A for transient protection scenarios.
• Operates reliably across an extended industrial temperature range from -40 °C to +125 °C.

Scrs Applications

• AC power control circuits requiring low voltage ratings
• General purpose rectification in industrial equipment
• Battery charging systems

Scrs Procurement Notes

Verify component authenticity and datasheet alignment before integration. Note that this specific part number is listed as discontinued or having restricted supply status. Confirm availability through authorized channels and check for end-of-life implications. Ensure the TO-3P-3 package compatibility matches existing board layouts and thermal management requirements.

Scrs Selection Notes

Select this component when a 200 V SCR rating is required in a TO-3P-3 package. Consider the 50 mA gate trigger current for driver design. Evaluate thermal dissipation needs given the 2.1 V forward voltage drop. Verify that the 75 mA holding current meets the minimum load requirements of the specific circuit application to ensure reliable latching.

Scrs Part Context

This device is part of the BTW68 family of SCRs from STMicroelectronics. The family offers various voltage ratings while maintaining similar packaging and performance characteristics. The BTW68-200RG specifically targets applications needing lower blocking voltages compared to higher-rated siblings in the same series.

Scrs Replacement Considerations

Check for direct pin-compatible substitutes within the BTW68 series with different voltage ratings if system voltage allows. Consult manufacturer documentation for cross-reference lists to identify equivalent components from other vendors with matching TO-3P-3 packages and electrical specifications.
