BTA330Y-800CTQ

Triacs Overview

The BTA330Y-800CTQ 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 through-hole mounting. The device supports an RMS on-state current of 30 A and withstands a rated repetitive peak off-state voltage of 800 V. It features a non-repetitive peak on-state current capability of 270 A and a maximum junction operating temperature of 150 °C. Key electrical parameters include a gate trigger current of 50 mA across quadrants Q1, Q2, and Q3, and a static dv/dt rating of 4000 V/µs.

Triacs Feature Summary

• High commutation capability allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Internally insulated plastic package providing enhanced safety and isolation
• Three quadrant sensitivity ensuring reliable triggering in all gate polarities
• High immunity to false turn-on due to elevated static dv/dt rating

Triacs Applications

• Industrial motor control circuits requiring high thermal stability
• Power switching applications subject to high static and dynamic dv/dt stress
• AC power regulation systems utilizing high junction operating temperature capabilities

Triacs Procurement Notes

Verify the specific suffix 'BTQ' against the datasheet to confirm the horizontal rail pack packaging format. Ensure the orderable part number matches the internal insulation requirements. Confirm RoHS compliance status and lead-free plating specifications prior to procurement to meet environmental standards.

Triacs Selection Notes

Select this component when circuit designs demand high thermal endurance up to 150 °C and robust commutation performance. The IITO220 package is suitable for applications requiring galvanic isolation between the terminal and heatsink. Verify that the 30 A RMS current rating aligns with the load requirements and that the 800 V voltage rating provides sufficient margin for line transients.

Triacs Part Context

This part belongs to the BTA series of planar passivated triacs from WeEn Semiconductors. It shares core electrical characteristics with variants like the BTA330X-800BTQ but differs in package type. The Y suffix typically denotes the TO-220AB form factor, while the CTQ suffix indicates the specific ordering and packing configuration.

Triacs Replacement Considerations

Direct replacements include BTA330X-800BTQ and BTA330Y-800BTQ. Note that package variations exist; verify pinout compatibility and insulation requirements when substituting between TO-220F and TO-220AB formats.
