BTA425Y-800CTQ

Triacs Overview

The BTA425Y-800CTQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in an internally insulated IITO220 (TO-220AB) plastic package designed for through-hole mounting. The device features a rated repetitive off-state voltage of 800 V and an on-state RMS current capability of 25 A. It supports a non-repetitive peak on-state current of 250 A and maintains a maximum junction temperature of 150 °C. Key electrical parameters include a holding current maximum of 60 mA, a gate trigger voltage of 700 mV, and a gate trigger current of 50 mA.

Triacs Feature Summary

• High commutation capability allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Internally insulated plastic package providing enhanced safety and isolation
• Planar passivated construction engineered to withstand high static and dynamic dV/dt and high dI/dt conditions

Triacs Applications

• Industrial circuits requiring high junction operating temperature capability
• Power switching applications subject to high static and dynamic dV/dt stress
• High dI/dt circuit environments where robust commutation is required

Triacs Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and marking variations. Confirm RoHS compliance status and lead-free conversion dates via official datasheets. Ensure the ordering part number matches the required insulation and thermal specifications for the target application environment.

Triacs Selection Notes

Select this component when designs demand high thermal stability up to 150 °C and robust performance under rapid voltage or current transients. The internally insulated TO-220AB package facilitates secure mounting while maintaining electrical isolation. Verify that the 25 A RMS rating and 800 V blocking voltage align with the system's operational limits and safety requirements.

Triacs Part Context

This triac belongs to the BTA425 series from WeEn Semiconductors, which focuses on high-performance thyristor solutions. The CTQ designation indicates a specific packaging and marking configuration within the broader BTA425 family. It shares core electrical characteristics with other variants but differs in physical housing and identification markings.

Triacs Replacement Considerations

Direct substitutes include BTA425Y-800BTQ and BTA425Z-800CTQ. Verify package compatibility and marking differences before substitution. Ensure the alternative part meets the same 800 V and 25 A ratings.
