BTA312-600E,127

Triacs Overview

The BTA312-600E,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a SOT78 (TO-220AB) plastic package and belongs to the "Series E" classification, which balances commutation performance with gate sensitivity for interfacing with low-power drivers like microcontrollers. Key electrical parameters include a rated repetitive peak off-state voltage (VDRM) of 600 V, an RMS on-state current (IT(RMS)) of 12 A, and a non-repetitive peak on-state current (ITSM) of 100 A. The device features a maximum gate trigger current (IGT) of 10 mA across quadrants Q1, Q2, and Q3, a dV/dt rating of 50 V/µs, and a maximum junction temperature (Tj) of 125°C.

Triacs Feature Summary

• Planar passivated construction designed for high commutation performance in three-quadrant operation.
• "Series E" sensitive gate architecture optimized for direct interfacing with low-power logic drivers and microcontrollers.
• Industrial qualification ensuring reliability for demanding electronic applications.

Triacs Applications

• Motor speed control circuits
• Solid-state relays
• Lighting dimmers

Triacs Procurement Notes

Verify the complete orderable part number BTA312-600E,127 against the manufacturer's official documentation to ensure correct Series E gate sensitivity and TO-220AB packaging. Confirm RoHS compliance and lead-free status as specified in the chemical content information. Cross-reference the 12NC code 9340 600 37127 for accurate inventory tracking and supply chain management.

Triacs Selection Notes

Select this component when a 12 A RMS current capacity and 600 V blocking voltage are required in a through-hole TO-220AB package. The "Series E" gate sensitivity (10 mA max IGT) makes it suitable for designs driven by low-power microcontrollers or logic gates without additional driver circuitry. Ensure the application operates within the 125°C maximum junction temperature limit and respects the 50 V/µt dV/dt specification.

Triacs Part Context

This triac is part of the BTA312 series from WeEn Semiconductors, specifically the "Series E" variant. It serves as a successor or alternative to previous generations like the BTA212-600E, which is marked as non-preferred for new designs. The BTA312 series maintains similar electrical characteristics but offers updated manufacturing processes and packaging options, including surface-mount variants like the BTA312B-600E in D2PAK packages.

Triacs Replacement Considerations

Publicly confirmed substitutes include other BTA312 series variants such as BTA312-600D (Series D, 5 mA IGT) or BTA312-800CT (800 V rating). Direct pin-compatible replacements from other manufacturers require verification of gate sensitivity and commutation ratings. Avoid using BTA212-600E for new designs as it is explicitly marked non-preferred.
