BTA204X-800E,127

Triacs Overview

The BTA204X-800E,127 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT186A (TO-220F) full pack plastic package designed for through-hole mounting. The device features an RMS on-state current of 4 A and a non-repetitive peak on-state current of 25 A. It supports a rated repetitive peak off-state voltage of 800 V with a maximum junction temperature of +125 °C. Key electrical parameters include a gate trigger current of 10 mA across all quadrants, a holding current maximum of 12 mA, and an on-state voltage of 1.4 V. The component exhibits a static dv/dt rating of 30 V/µs and a leakage current of 100 µA at VDRM.

Triacs Feature Summary

• Three quadrant operation ensures reliable commutation performance under varying load conditions.
• Sensitive gate design facilitates direct interfacing with low power drivers and logic ICs including microcontrollers.
• Planar passivation technology provides robust protection against environmental stress and enhances device longevity.

Triacs Applications

• Motor control circuits requiring high commutation capability
• Inductive load switching applications
• General purpose AC power control systems

Triacs Procurement Notes

Verify the complete part number including the ordering suffix to ensure correct packaging configuration. Confirm RoHS compliance status and lead-free plating specifications prior to integration. Cross-reference the manufacturer's latest datasheet for any updates regarding industrial qualification or chemical content declarations to maintain supply chain integrity.

Triacs Selection Notes

Select this component when designing circuits that require sensitive gate triggering from microcontrollers while maintaining high commutation performance. Ensure the thermal management solution supports the TO-220F package and the maximum junction temperature of 125 °C. Verify that the circuit's dv/dt requirements do not exceed the specified 30 V/µs limit without additional snubber networks.

Triacs Part Context

This part belongs to the Series E triac family from WeEn Semiconductors, which balances gate sensitivity with commutation performance. It serves as a specialized variant within the broader BTA204 product line, distinguished by its specific gate characteristics and TO-220F packaging. The Series E designation indicates optimization for low-power driver interfaces compared to standard series.

Triacs Replacement Considerations

The BTA204-800E is a related variant utilizing a TO-220AB package rather than the TO-220F full pack. Designers must verify pinout compatibility and mechanical footprint differences before substitution. Other Series E triacs may offer different current ratings but share similar gate sensitivity profiles.
