T1650H-6I

Overview

The T1650H-6I is a medium current Triac from the H-Series, rated for 16 A RMS on-state current and 600 V repetitive peak off-state voltage. It operates within a junction temperature range of -40 °C to +150 °C. The device features a maximum on-state voltage of 1.5 V, a holding current of 75 mA, and gate trigger parameters of 1 V and 50 mA. Packaged in an insulated TO-220AB (Ecopack2) format with a non-repetitive surge current capability of 168 A, it supports general-purpose mains power AC switching applications.

Feature Summary

• High thermal performance enabling operation up to 150 °C junction temperature
• Snubberless design allowing direct use without external RC networks
• Insulated package providing 2500 V rms isolation between tab and terminals

Applications

• General purpose mains power AC switching
• Phase angle control circuits
• Industrial motor control systems

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number and date code against official STMicroelectronics documentation. Confirm that the Ecopack2 package matches the specified TO-220AB Insulated form factor. Ensure compliance with RoHS directives and UL certification requirements relevant to the specific application environment before finalizing procurement.

Selection Notes

Select this component when high commutation capability and elevated temperature operation are required. The logic level gate drive compatibility facilitates direct interfacing with microcontrollers. Verify that the 16 A RMS rating and 600 V blocking voltage align with the circuit's electrical demands and load characteristics.

Part Context

This Triac belongs to the H-Series family designed for robust industrial applications. It shares common architectural traits with other Snubberless devices in the lineup but is distinguished by its specific 16 A current rating and 150 °C thermal limit. The series emphasizes reduced heatsink requirements due to efficient thermal management.

Replacement Considerations

The T1635H-6I serves as a higher current alternative within the same series. Designers should verify that the increased current handling does not necessitate changes to existing thermal management structures or PCB trace widths.
