BTA425X-800BQ

Triacs Overview

The BTA425X-800BQ is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220F (SOT186A) full pack plastic package designed for through-hole mounting. The device supports an RMS on-state current of 25 A and withstands a rated repetitive peak off-state voltage of 800 V. It features a non-repetitive peak on-state current of 275 A, a maximum on-state voltage of 1.2 V, and a gate trigger current of 50 mA across all quadrants. The component operates within a temperature range up to +150°C.

Triacs Feature Summary

• Three quadrant Hi-Com technology providing improved noise immunity and high immunity to false turn-on by dv/dt
• Planar passivated construction ensuring robust performance under high static and dynamic dV/dt conditions
• Capable of commutating the full rated RMS current at maximum junction temperature without requiring a snubber circuit

Triacs Applications

• High power motor control systems
• Industrial heating applications
• Lighting dimmers

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and packing method. Ensure compliance with RoHS and REACH requirements as specified in the product data sheet. Confirm that the TO-220F full pack variant matches the thermal and mechanical constraints of the target design before finalizing procurement.

Triacs Selection Notes

Select this component when high commutation capability is required without external snubber networks. The 800 V rating suits general industrial AC line applications. Verify that the 25 A RMS current capacity aligns with the load requirements. Consider the TO-220F package for adequate heat dissipation in through-hole PCB layouts.

Triacs Part Context

This part belongs to the BTA425X series of three quadrant triacs from WeEn Semiconductors. It shares the core electrical characteristics of the BTA425X-800B but utilizes the 'Q' suffix to denote specific packaging or marking variations. It is distinct from lower current variants like the BTA16 or higher current packages like the BTA450Z.

Triacs Replacement Considerations

Direct replacements include the BTA425X-800BTQ. Verify pinout compatibility and thermal resistance values when substituting with other TO-220F triacs from different manufacturers.
