TMA86G-L

Overview

The TMA86G-L is an 8A Triac manufactured by Sanken Electric USA Inc., housed in a TO-220F package. It is designed for AC power control applications, featuring a gate trigger voltage of 1.3V and a holding current of 40mA. The device supports a repetitive peak off-state voltage of 600V and operates within a junction temperature range of -40°C to +125°C. With a non-repetitive peak surge current capability of 70A, it provides robust performance for industrial and consumer AC switching tasks.

Feature Summary

• Integrated thermal protection mechanisms for enhanced reliability under overload conditions
• Snubberless design capability simplifies circuit layout and reduces component count
• High surge current handling ensures durability during transient electrical events

Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits

Procurement Notes

Verify the specific suffix configuration against the official Sanken Electric datasheet to ensure compatibility with required voltage and current ratings. Confirm RoHS compliance status and packaging options directly with authorized distributors prior to ordering. Cross-reference part numbers to avoid substitution errors in production lines.

Selection Notes

Select this component based on its 600V blocking voltage and 8A continuous current capacity. Ensure the application requires a snubberless operation or benefits from integrated thermal shutdown features. Validate that the TO-220F package fits the thermal management constraints of the target enclosure.

Part Context

This triac belongs to Sanken's standard thyristor family, optimized for general-purpose AC switching. It complements other devices like the TM861 and TF821M, offering a balance between high current handling and compact surface-mount compatible packaging solutions for modern power electronics designs.

Replacement Considerations

Potential substitutes include the TM861 or TM861S from Apollo Electron, and the HTX8-600 from Hi-Sincerity Microelect. Verify pinout compatibility and thermal resistance values before implementation.
