BTA225-600B,127

Triacs Overview

The BTA225-600B,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220 plastic package and designed for circuits experiencing high static and dynamic dV/dt and dI/dt conditions. The device supports an RMS on-state current of 25 A and a non-repetitive peak on-state current of 190 A at 50/60 Hz. It features a rated repetitive peak off-state voltage of 600 V and a maximum junction temperature of 125°C. The component requires a maximum gate trigger current of 50 mA across quadrants Q1, Q2, and Q3.

Triacs Feature Summary

• High commutation capability allows full rated RMS current commutation at maximum junction temperature without snubber assistance.
• Planar passivated construction provides robustness against high static and dynamic dV/dt and dI/dt stresses.
• Three-quadrant operation ensures reliable triggering and switching performance across all gate signal polarities.

Triacs Applications

• Industrial motor control systems requiring high surge tolerance
• AC power regulation circuits with rapid voltage transients
• High-power lighting dimmer applications

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing method. The part number BTA225-600B,127 corresponds to the TO-220 package with horizontal rail pack configuration. Confirm RoHS compliance status and lead-free conversion dates through official manufacturer documentation before procurement.

Triacs Selection Notes

Select this component when a through-hole TO-220 package is required for high-current AC switching applications. Ensure the circuit design accommodates the 125°C maximum junction temperature limit. Verify that the application does not exceed the 1000 V/µs dV/dt rating during commutation events.

Triacs Part Context

This component belongs to the BTA225 series of high commutation triacs from WeEn Semiconductors. The series includes variants with different voltage ratings such as the BTA225-800B and surface-mount versions like the BTA225B-600B. The BTA225-600B,127 specifically denotes the 600V version in the traditional TO-220 axial leaded package.

Triacs Replacement Considerations

Direct replacements include other BTA225 series parts with identical current ratings but different voltage or package options, such as BTA225-800B,127 for higher voltage or BTA225B-600B,118 for surface mount. Cross-brand equivalents must match the 25A RMS current and TO-220 footprint constraints.
