BTA16-600BQ

Triacs Overview

The BTA16-600BQ is a planar passivated four-quadrant triac manufactured by WeEn Semiconductors, housed in an internally insulated IITO-220 (SOT78D) plastic package. It features a rated repetitive peak off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 16 A at a mounting base temperature of 112 °C. The device supports a non-repetitive peak on-state current (ITSM) of 160 A for 20 ms pulses and 176 A for 16.7 ms pulses. It operates with a maximum junction temperature (Tj) of 150 °C and provides 2500 V (RMS) isolation between the pins and the external heatsink.

Triacs Feature Summary

• Four-quadrinal triggering capability ensures reliable operation across all gate and main terminal polarities.
• Internally insulated package design provides high isolation voltage between terminals and mounting base.
• Planar passivation technology enhances voltage ruggedness and long-term reliability.
• High minimum gate trigger current guarantees immunity against spurious gate noise.

Triacs Applications

• Compressor starting control circuits
• General purpose motor controls
• General purpose bidirectional switching

Triacs Procurement Notes

Verify the specific ordering suffix to confirm packaging format, as the datasheet lists BTA16-600BQ associated with horizontal rail pack distribution. Confirm RoHS compliance status and lead-free conversion dates through official manufacturer channels prior to procurement. Ensure the component matches the required industrial qualification standards for the intended application environment.

Triacs Selection Notes

Select this component when high noise immunity is critical due to its elevated gate trigger current specifications. The internally insulated package is suitable for applications requiring galvanic isolation from the heatsink without additional insulators. Verify that the thermal resistance characteristics and mounting base temperature limits align with the system's cooling capabilities to maintain junction temperatures within the 150 °C maximum rating.

Triacs Part Context

This part belongs to the BTA16 series of four-quadrant triacs produced by WeEn Semiconductors. The 'Q' suffix typically denotes specific packaging or handling variations compared to the standard BTA16-600B, though functional parameters remain consistent with the base model. It serves as a general-purpose power switching device within the company's discrete semiconductor portfolio.

Triacs Replacement Considerations

Direct replacements must match the 600 V voltage rating, 16 A current capacity, and IITO-220 package outline. Verify that substitute components offer comparable dV/dt ratings and gate trigger currents to ensure equivalent noise immunity and switching performance in existing circuit designs.

Triacs FAQ
