BTA204S-800E,118

Triacs Overview

The BTA204S-800E,118 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO252 (DPAK) surface-mountable plastic package and operates within an industrial temperature range up to +125°C. The device features a rated repetitive off-state voltage of 800 V and an RMS on-state current of 4 A. Key electrical parameters include a non-repetitive peak on-state current of 27 A, a maximum holding current of 12 mA, and a gate trigger current of 10 mA across quadrants Q1, Q2, and Q3. The component exhibits a typical on-state voltage of 1.4 V and a leakage current of 100 uA at the rated voltage.

Triacs Feature Summary

• Balances commutation performance with gate sensitivity for interfacing with low power drivers and logic ICs including microcontrollers
• Designed for circuits where high static and dynamic dV/dt conditions occur
• Capable of full rated RMS current commutation at maximum junction temperature without snubber assistance

Triacs Applications

• Interfacing with low power drivers and logic ICs including microcontrollers
• High commutation applications requiring robust dV/dt handling
• Industrial circuits operating at maximum rated junction temperatures

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and packing configuration. Confirm RoHS compliance status and lead-free conversion dates via the latest chemical content reports. Ensure the selected variant matches the required thermal management capabilities for the intended application environment.

Triacs Selection Notes

Select this component when a surface-mount solution is required for high commutation applications. The DPAK package suits designs needing compact footprints while maintaining industrial temperature ratings. Verify that the 4 A RMS current rating meets load requirements and that the 800 V blocking voltage aligns with system line voltages.

Triacs Part Context

This part belongs to the BTA204 series of planar passivated triacs from WeEn Semiconductors. The 'Series E' designation indicates a balance between commutation performance and gate sensitivity. It shares the same core semiconductor structure as through-hole variants but utilizes a surface-mountable TO252 package for automated assembly compatibility.

Triacs Replacement Considerations

T410-800B-TR by STMicroelectronics is a documented alternative.
