BTA312B-600CT,118

Triacs Overview

The BTA312B-600CT,118 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT404 (D2PAK/TO263) surface-mountable plastic package designed for circuits experiencing high static and dynamic dV/dt and dI/dt conditions. The device features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 12 A. It supports a non-repetitive peak on-state current of 100 A and operates with a maximum junction temperature of 150 °C. The component exhibits a gate trigger current of 35 mA across quadrants Q1, Q2, and Q3, with a static dV/dt rating of 300 V/µs.

Triacs Feature Summary

• High commutation capability allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Planar passivated construction optimized for environments with high static and dynamic dV/dt and dI/dt stress
• Three-quadrant switching functionality suitable for robust industrial applications

Triacs Applications

• Industrial circuits requiring high junction operating temperature capability
• Power control systems subject to high static and dynamic voltage and current rates of change
• Applications necessitating snubberless operation at elevated temperatures

Triacs Procurement Notes

Verify the complete ordering part number includes the suffix ,118 to ensure correct reel packing configuration. Confirm RoHS compliance and lead-free plating status against the specific manufacturing batch documentation. Ensure the procurement source provides the official chemical content declaration and MSL classification data required for assembly processes.

Triacs Selection Notes

Select this variant when a maximum junction temperature of 150 °C is required, distinguishing it from standard series C devices limited to 125 °C. The TO263 package facilitates surface mount integration while maintaining thermal performance. Verify that the 300 V/µs dV/dt rating meets the specific circuit requirements, as other series variants offer higher or lower commutation speeds.

Triacs Part Context

This component belongs to the BTA312B series of high commutation triacs from WeEn Semiconductors. The 'CT' suffix specifically denotes the 'series CT' designation, which differentiates the device by its enhanced thermal capability up to 150 °C compared to the standard 125 °C limit found in other series like B or C. It shares the same electrical ratings but targets high-temperature reliability.

Triacs Replacement Considerations

The BTA312B-600C,118 serves as a direct functional substitute if the application does not require the extended 150 °C junction temperature capability, as it shares identical electrical parameters except for the thermal limit.
