BTA25-800CW3G

Triacs Overview

The Littelfuse BTA25-800CW3G is a standard triac designed for AC switching applications. It features an RMS on-state current rating of 25 A and a repetitive peak off-state voltage of 800 V. The device operates within a temperature range of -40°C to +125°C and utilizes a TO-220 package for through-hole mounting. Key electrical parameters include a maximum gate trigger current of 35 mA, a holding current of 50 mA, and a non-repetitive peak surge current capability of 250 A.

Triacs Feature Summary

• Integrated thermal protection mechanism
• High surge current handling capability

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• General-purpose AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix 'CW3G' against manufacturer documentation to confirm exact pinout configuration and thermal characteristics. Ensure compliance with RoHS directives if required by the target assembly specifications. Cross-reference datasheet revisions to validate parameter consistency before finalizing component selection.

Triacs Selection Notes

Select this component when high current capacity and robust surge tolerance are required in a thermally isolated package. Evaluate the 800 V blocking voltage against system line peaks. Confirm that the 35 mA gate drive requirement aligns with the available control circuit output capabilities.

Triacs Part Context

This part belongs to the BTA series of standard triacs manufactured by Littelfuse. It serves as a high-current alternative to lower-rated devices like the BTA12 or BTA16. The TO-220 form factor distinguishes it from surface-mount options, providing direct heatsink mounting capabilities for thermal management.

Triacs Replacement Considerations

Equivalent parts include the STMicroelectronics BTA25-800B and the WeEn Semiconductors BTA25-800C. Verify pin compatibility and thermal resistance values before substitution.
