BTA316B-600BT,118

Triacs Overview

The BTA316B-600BT,118 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO263 surface-mountable plastic package and designed for circuits with high static and dynamic dV/dt and dI/dt. The device supports full RMS current commutation at a maximum junction temperature of 150 °C without requiring a snubber circuit. Key electrical parameters include a repetitive peak reverse voltage (VRRM) and direct current off-state voltage (VDRM) of 600 V, an on-state root mean square current (IT(RMS)) of 16 A, and a non-repetitive peak on-state current (ITSM) of 140 A. Gate trigger currents are rated at 50 mA across quadrants Q1, Q2, and Q3, with a critical rate of rise of off-state voltage (dVD/dt) of 1000 V/µs.

Triacs Feature Summary

• High commutation capability allows full RMS current switching at maximum rated junction temperatures without external snubber assistance.
• Planar passivation technology provides robust protection against high static and dynamic dV/dt and dI/dt conditions.
• Three quadrant logic level operation ensures reliable triggering across multiple gate polarity configurations.

Triacs Applications

• Industrial motor control systems requiring high thermal stability
• Solid state relays operating under high dv/dt stress
• Lighting dimmers and power regulation circuits

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the package type and packing method. The BTA316B-600BT,118 designation corresponds to the TO263 package with reel packing oriented to Q1/T1. Confirm RoHS compliance and lead-free status through official manufacturer documentation before procurement to ensure alignment with assembly requirements.

Triacs Selection Notes

Select this component when a surface-mount solution is required for high-power applications demanding commutation at elevated temperatures up to 150 °C. Ensure the application environment does not exceed the specified 600 V blocking voltage or 16 A RMS current limits. Verify that the gate drive circuitry can supply the necessary 50 mA trigger current for all three quadrants.

Triacs Part Context

This part belongs to the BTA316 series of high commutation triacs from WeEn Semiconductors. The series includes variants with different packages such as TO220 and TO263, and different thermal ratings. The 'BT' suffix typically denotes the higher temperature rating variant compared to other series members like 'B' or 'E'.

Triacs Replacement Considerations

Direct replacements must match the TO263 package, 600 V rating, 16 A current capacity, and 150 °C junction temperature limit. Verify pinout compatibility and gate sensitivity specifications to ensure functional equivalence in existing designs.
