T610H-6T

Overview

The T610H-6T is a logic level H-series TRIAC manufactured by STMicroelectronics, rated for 6 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a maximum junction temperature of 150 °C and utilizes TO-220AB through-hole packaging. The device specifies a gate trigger current (I_GT) lower than 10 mA, enabling direct logic-level switching without derating at high temperatures. Key electrical characteristics include a holding current of 35 mA maximum and an on-state voltage drop of approximately 1.7 V at rated conditions. It offers high noise immunity with a dV/dt rating of 75 V/µs up to the maximum junction temperature.

Feature Summary

• Logic level sensitivity with gate trigger current below 10 mA for direct microcontroller interfacing
• High thermal performance allowing operation up to 150 °C junction temperature
• Enhanced commutation capabilities and high noise immunity valid up to maximum operating temperature

Applications

• General purpose mains power AC switching
• Heater control circuits
• Motor drive applications
• Small appliance control systems

Procurement Notes

Verify the specific suffix '6T' against the official datasheet to confirm package type and pinout configuration. Ensure the procurement source provides the original manufacturer's documentation rather than third-party summaries. Confirm RoHS compliance status as per the latest ECOPACK standards before finalizing orders.

Selection Notes

Select this component when designing circuits requiring direct logic-level gate drive without additional driver transistors. The 150 °C rating allows for reduced heatsink size compared to standard TRIACs. Verify that the load current does not exceed 6 A RMS and that the circuit can handle the specified 75 V/µt noise immunity requirements in high-interference environments.

Part Context

The T610H-6T belongs to STMicroelectronics' H-series of medium current TRIACs. This series is engineered specifically for high-temperature operation, distinguishing it from standard commercial-grade TRIACs limited to 125 °C. It shares the logic-level technology found in the T410H and T1010H models but is optimized for 6 A applications.

Replacement Considerations

Direct replacements within the same family include the T410H (4 A) or T1010H (10 A) if current ratings allow adjustment. For non-ST equivalents, verify that substitute TRIACs maintain the 10 mA logic-level gate sensitivity and 150 °C junction temperature capability to ensure thermal and interface compatibility.
