BTA201-800E,412

Triacs Overview

The BTA201-800E,412 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT54 (TO-92) plastic package designed for through-hole mounting. This component belongs to the series E triac family, which balances commutation performance with gate sensitivity to facilitate interfacing with low power drivers and logic ICs, including microcontrollers. Key electrical parameters include a rated repetitive peak off-state voltage of 800 V, an RMS on-state current of 1 A, and a non-repetitive peak on-state current of 12.5 A. The maximum junction temperature is specified at 125 C, and it features a dV/dt rating of 600 V/us.

Triacs Feature Summary

• Three quadrant operation providing high commutation capabilities
• Planar passivated construction for enhanced reliability
• Optimized gate sensitivity for direct interface with low power drivers and logic ICs

Triacs Applications

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact marking and packaging details. Confirm RoHS compliance status via the latest product data sheet before integration into designs requiring environmental certification.

Triacs Selection Notes

Select this component when a compact TO-92 package is required for AC switching applications involving low current loads. Ensure the driving circuit can supply the necessary gate trigger current and that the operating environment remains within the specified thermal limits.

Triacs Part Context

This part is part of the WeEn Semiconductors series E triac lineup. These devices are engineered to offer a balance between robust commutation performance and high gate sensitivity, making them suitable for modern digital control systems where low drive power is available.

Triacs Replacement Considerations

Check for equivalent parts from other manufacturers offering similar 800 V ratings and TO-92 packages. Verify pinout compatibility and ensure that alternative components meet the same three quadrant commutation requirements.
