BTA204-800C,127

Triacs Overview

The BTA204-800C,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 800 V rated repetitive off-state voltage and supports a 4 A RMS on-state current. It includes a non-repetitive peak on-state current capability of 25 A. The component operates within a junction temperature range up to +125 °C and exhibits a maximum holding current of 12 mA.

Triacs Feature Summary

• Planar passivated construction ensures robust performance under high static and dynamic dv/dt conditions.
• Three-quadrant design provides high commutation capabilities without requiring external snubber circuits.
• Full pack TO-220F plastic package facilitates efficient thermal dissipation and mechanical stability.

Triacs Applications

• High-power AC motor speed control systems
• Industrial solid-state relay switching applications
• Lighting dimmer circuits with high load requirements

Triacs Procurement Notes
