BTA312B-600E,118

Triacs Overview

The BTA312B-600E,118 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT404 (D2PAK) surface mountable plastic package, specifically TO263. The device features a rated repetitive peak off-state voltage of 600 V and an on-state RMS current of 12 A. Non-repetitive peak on-state current is specified at 100 A. The maximum gate trigger current is 10 mA across quadrants Q1, Q2, and Q3. It supports a static and dynamic dV/dt rating of 50 V/µs and operates with a maximum junction temperature of 125 °C. This series E triac balances commutation performance with gate sensitivity for low power driver interfacing.

Triacs Feature Summary

• Planar passivated construction designed for high commutation applications
• Sensitive gate architecture optimized for microcontroller and low power driver interfacing
• Surface mountable D2PAK package configuration

Triacs Applications

• High frequency switching circuits requiring high static and dynamic dV/dt immunity
• Motor speed control systems utilizing low power logic drivers
• Solid state relay interfaces demanding sensitive gate triggering

Triacs Procurement Notes

Verify the complete orderable part number includes the specific packing suffix to ensure correct reel specifications. Confirm RoHS compliance status and lead-free plating requirements against project constraints. Check industrial qualification standards and MSL ratings for assembly compatibility. Validate chemical content information if restricted substance management is required for the target market.

Triacs Selection Notes

Select this component when interfacing with low power drivers such as microcontrollers that require sensitive gate triggering characteristics. Ensure the application circuit can handle the specified 50 V/µs dV/dt rating without additional snubber networks. Verify that the thermal design accommodates the 125 °C maximum junction temperature limit under full load conditions.

Triacs Part Context

This part belongs to the BTA312 series of three quadrant triacs from WeEn Semiconductors. The 'Series E' designation indicates a specific balance between commutation performance and gate sensitivity. It shares the same physical package and core electrical ratings as other variants like the BTA312B-600CT but differs in gate sensitivity and dV/dt robustness specifications.

Triacs Replacement Considerations

Direct substitutes within the same family include BTA312B-600CT and BTA312B-600B. Note that these alternatives offer higher dV/dt ratings and different gate sensitivities. Verify if the increased dV/dt capability or altered gate current requirements align with the existing circuit design before substitution.
