BTA204-800E,127

Triacs Overview

The BTA204-800E,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT78 (TO-220AB) plastic package designed for through-hole mounting. The device features an 800 V rated repetitive peak off-state voltage and supports a 4 A RMS on-state current with a non-repetitive surge current capacity of 25 A. It operates within a junction temperature range up to +125 °C and includes a maximum gate trigger current of 10 mA across quadrants Q1, Q2, and Q3.

Triacs Feature Summary

• High commutation capability suitable for circuits with high static and dynamic dv/dt and di/dt conditions
• Three-quadrant operation balances commutation performance with gate sensitivity
• Logic-compatible interface designed for low power drivers and microcontrollers

Triacs Applications

• Interfacing with low power drivers and logic ICs including microcontrollers
• High commutation applications requiring immunity to false turn-on
• Industrial control circuits utilizing standard TO-220AB mounting

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and packing configuration. Ensure the component meets RoHS compliance and lead-free requirements as specified in the chemical content information. Cross-reference the 12NC code 9340 562 90127 with authorized distributors to validate availability and authenticity before procurement.

Triacs Selection Notes

Select this component when a three-quadrant triac with high commutation performance is required for logic-level interfacing. The 800 V rating and 4 A current capacity define its operational limits. Consider the TO-220AB package for thermal management needs. Verify that the 10 mA gate trigger current aligns with the driving circuit capabilities for reliable switching in industrial environments.

Triacs Part Context

This part belongs to the BTA204 series of planar passivated triacs from WeEn Semiconductors. The 'E' designation indicates a specific variant optimized for balancing commutation performance and gate sensitivity. It is distinct from other series like the BTA420 or BTA330B which may feature different technologies such as 3Q Hi-Com or higher current ratings.

Triacs Replacement Considerations

Direct substitutes must match the 800 V rating, 4 A RMS current, and TO-220AB package. Verify compatibility with three-quadrant operation and similar gate trigger characteristics. Consult the manufacturer's cross-reference guide for approved alternatives ensuring identical electrical parameters and physical dimensions.
