BTA308Y-800C0TQ

Triacs Overview

The BTA308Y-800C0TQ is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in an internally insulated IITO-220 (SOT78D) plastic package designed for motor control applications requiring high blocking voltage and robust dv/dt and di/dt immunity. Key electrical parameters include a rated repetitive off-state voltage of 800 V, an RMS on-state current of 8 A, and a non-repetitive peak on-state current of 60 A. The device maintains a maximum on-state voltage of 1.3 V and a gate trigger current of 35 mA across quadrants Q1, Q2, and Q3. It operates within a junction temperature range up to 150 °C and features a static dV/dt rating of 2000 V/µs.

Triacs Feature Summary

• Three-quadrant operation with identical gate trigger currents across all quadrants for simplified drive circuitry.
• Internally isolated mounting base providing enhanced safety and thermal management in industrial environments.
• High commutation capability allowing full rated RMS current switching at maximum junction temperature without snubber circuits.

Triacs Applications

• Motor control circuits subject to high static and dynamic dv/dt conditions
• Industrial systems requiring high blocking voltage and high di/dt commutation
• General purpose AC power switching where internal insulation is required

Triacs Procurement Notes

Verify the specific suffix C0T against the official datasheet to confirm the IITO-220 package and horizontal rail pack configuration. Ensure the ordering part number matches the volume production status listed in the manufacturer's documentation. Cross-reference the 12NC code 9340 720 53127 for accurate inventory tracking and compliance verification.

Triacs Selection Notes

Select this component when an internally insulated triac is required for motor drives or high-noise industrial environments. The 800 V rating suits standard mains applications, while the 8 A RMS current defines the load capacity. Verify that the 35 mA gate trigger current aligns with the available driver output capabilities across all operating quadrants.

Triacs Part Context

This device belongs to the BTA308 series of planar passivated triacs from WeEn Semiconductors. The series is characterized by high commutation performance and robust construction for demanding industrial applications. The specific C0T variant denotes the IITO-220 package with internal isolation, distinguishing it from standard TO-220 variants lacking insulation.

Triacs Replacement Considerations

Direct substitutes must match the 800 V voltage rating, 8 A RMS current, and IITO-220 insulated package. Verify compatibility of the 35 mA gate trigger current and 150 °C maximum junction temperature. Check for equivalent dV/dt ratings of 2000 V/µs to ensure reliable commutation in existing designs.
