BTA330Y-800BTQ

Triacs Overview

The BTA330Y-800BTQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in an internally insulated TO-220AB (IITO220) plastic package designed for circuits requiring high static and dynamic dV/dt and dI/dt immunity. The device supports an RMS current of 30 A with a non-repetitive peak on-state current of 270 A. It features a rated repetitive off-state voltage of 800 V, a maximum on-state voltage of 1.2 V, and a gate trigger current of 50 mA across all quadrants. The component operates within a temperature range of -40°C to +150°C junction temperature.

Triacs Feature Summary

• Three-quadrion Hi-Com technology providing improved noise immunity and high resistance to false turn-on caused by rapid voltage changes.
• Internally insulated plastic package construction suitable for applications requiring thermal isolation and robust physical mounting.
• High commutation capability allowing full RMS current switching at maximum rated junction temperatures without external snubber circuits.

Triacs Applications

• Industrial motor control systems requiring high dv/dt immunity
• Solid-state relay designs for AC load switching
• Lighting control circuits with high transient voltage exposure

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and marking conventions. Ensure that the requested variant matches the required insulation class and terminal configuration for your PCB layout. Cross-reference the 12NC code to validate production status and compliance certifications before finalizing procurement orders.

Triacs Selection Notes

Select this component when circuit requirements demand a 30 A RMS current rating with 800 V blocking capability in a through-hole insulated package. Consider the 50 mA gate trigger current specification for driver interface compatibility. Evaluate thermal management needs based on the 150°C maximum junction temperature limit and the specific heat dissipation characteristics of the TO-220AB housing.

Triacs Part Context

This part belongs to the BTA330 series of three-quadrant triacs from WeEn Semiconductors. It shares core electrical specifications with other variants in the family but differs in packaging and mechanical attributes. The Y suffix typically denotes the specific lead frame and molding compound configuration associated with the TO-220AB insulated package style.

Triacs Replacement Considerations

Direct replacements include BTA330X-800BTQ, which offers identical electrical ratings but utilizes a TO-220F package instead of TO-220AB. Verify pinout compatibility and thermal resistance differences when substituting between these package types.
