BTA204-800C/DG,127

Triacs Overview

The BTA204-800C/DG,127 is a standard gate Rail Triac manufactured by WeEn Semiconductors. It features an 800 V repetitive off-state voltage and a 4 A RMS on-state current capability. The device supports a non-repetitive peak on-state current of 25 A and operates within a junction temperature range up to 125°C. Packaged in a TO-220AB through-hole configuration with three terminals, this component is designed for robust AC power control applications requiring reliable switching performance.

Triacs Feature Summary

• Standard gate triggering characteristics for predictable switching behavior
• Rail Triac construction optimized for high reliability in industrial environments
• Through-hole mounting suitable for secure mechanical attachment

Triacs Applications

• Industrial motor speed control systems
• General purpose AC power regulation circuits
• Lighting dimmer implementations

Triacs Procurement Notes

Verify the specific suffix DG against the manufacturer datasheet to confirm pinout and thermal characteristics match design requirements. Ensure the TO-220AB package dimensions align with PCB layout constraints. Cross-reference the 800V rating with system voltage peaks to maintain adequate safety margins during operation.

Triacs Selection Notes

Select this component when a standard gate Triac is required for moderate power levels up to 4A. Compare against higher sensitivity variants if lower gate drive current is necessary. Consider thermal management solutions given the through-hole package limitations for continuous high-current loads.

Triacs Part Context

This part belongs to the BTA204 series of Rail Triacs from WeEn Semiconductors. It shares the base electrical architecture with other variants in the family but differs in gate sensitivity and voltage ratings. The TO-220AB package provides a balance between thermal dissipation and board space efficiency for general-purpose thyristor applications.

Triacs Replacement Considerations

The BT136-800E,127 is a documented comparable alternative within the same manufacturer portfolio. Verify gate trigger parameters and package compatibility before substitution.
