T1210T-6I

Triacs Overview

The T1210T-6I is a bidirectional triac from STMicroelectronics designed for general-purpose AC switching applications. It features a through-hole TO-220-3 package and supports an RMS on-state current of 12 A with a non-repetitive peak current of 95 A. The device has a rated repetitive off-state voltage (VDRM) of 600 V and a maximum holding current of 10 mA. Gate triggering parameters include a voltage of 1.3 V and a current of 10 mA. The component operates within a temperature range of -40°C to +125°C, exhibits an on-state voltage of 1.55 V, and maintains an off-state leakage current of 5 µA at VDRM.

Triacs Feature Summary

• Snubberless logic level design optimized for direct microcontroller control
• High static and dynamic commutation capability for resistive loads
• Insulated TO-220AB package providing 2500 V rms isolation

Triacs Applications

• On/off or phase angle control in general purpose AC switching
• Value-sensitive appliances requiring high commutation capability
• Motor control circuits in power tools and kitchen appliances

Triacs Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official datasheet before procurement. Confirm that the TO-220-3 insulated package meets the required insulation voltage ratings for the target application. Ensure compliance with RoHS directives and UL certification requirements relevant to the end product's safety standards.

Triacs Selection Notes

Select this component when a medium-current triac with high noise immunity and low gate drive requirements is needed. The 10 mA gate trigger current allows direct interfacing with standard logic outputs. Consider the thermal resistance and junction temperature limits for heat dissipation planning in enclosed appliance designs.

Triacs Part Context

This part belongs to the T12T series of Triacs, which are engineered for value-sensitive appliances. The series provides parameter guidance for designers focusing on cost-effective solutions without compromising performance in AC switching environments where robust commutation is essential.

Triacs Replacement Considerations

Check for equivalent Snubberless TRIACs with matching 600 V blocking voltage and 12 A current ratings. Verify pinout compatibility for TO-220 packages if substituting with devices from other manufacturers.
