BTA425Z-800BTQ

Triacs Overview

The BTA425Z-800BTQ is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in an IITO3P package and designed for circuits experiencing high static and dynamic dV/dt and high di/dt conditions. The device supports full RMS current commutation at a maximum junction temperature of 150 °C without requiring a snubber circuit. Key electrical parameters include a rated repetitive off-state voltage (VDRM) of 800 V, an on-state RMS current (IT(RMS)) of 25 A, and a non-repetitive peak on-state current (ITSM) of 250 A. Maximum gate trigger currents are specified as 35 mA across quadrants Q1, Q2, and Q3, with a dV/dt rating of 1000 V/µs.

Triacs Feature Summary

• Planar passivated construction ensures voltage ruggedness and long-term reliability.
• Three quadrant Hi-Com technology provides improved noise immunity and high resistance to false turn-on caused by dv/dt.
• Capable of commutating full RMS current at the maximum rated junction temperature without external snubber assistance.

Triacs Applications

• Industrial motor control systems
• High-voltage AC power switching applications
• Circuits requiring high thermal cycling performance

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and marking variations. Confirm RoHS compliance status and lead-free conversion dates through the latest datasheet or product change notifications. Ensure the requested part number matches the exact industrial qualification requirements for the target application environment.

Triacs Selection Notes

Select this component when high commutation capability and operation up to 150 °C junction temperature are required without snubber circuits. Compare the 25 A RMS current rating and 800 V blocking voltage against system load requirements. Consider the IITO3P package constraints for thermal management and PCB layout compared to alternative packages like TO220F.

Triacs Part Context

This part belongs to the BTA425Z series of three quadrant triacs from WeEn Semiconductors. It shares core electrical characteristics with variants such as the BTA425Z-800CT and BTA425X-800BT, differing primarily in packaging formats like IITO3P versus TO220F. The series is engineered for robust performance in demanding industrial environments involving high transient voltages.

Triacs Replacement Considerations

Potential substitutes within the same family include BTA425Z-800CT for identical electrical performance in an IITO3P package. For different mounting requirements, the BTA425X-800BT offers similar specifications in a TO220F package. Verify pinout compatibility and thermal resistance differences before substitution.
