T16M35T800UB

Overview

The T16M35T800UB is a silicon bidirectional thyristor (Triac) manufactured by Diodes Incorporated. It features an 800 V repetitive peak off-state voltage and a 16 A RMS on-state current rating. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger current of 35 mA, a holding current maximum of 50 mA, and an on-state voltage of 1.6 V at 16 A. It utilizes a TO-220AB package with matte tin-plated leads.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packing quantity and carrier type. Confirm that the component meets all applicable regulatory standards required for the target market, including RoHS compliance and flammability ratings. Cross-reference the datasheet revision number to guarantee access to the most current technical specifications and mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this component based on its 800 V blocking voltage and 16 A continuous current capacity. Ensure the application circuit respects the specified dI/dt limits and thermal resistance values to maintain safe operation within the +125°C junction temperature limit. Verify that the gate trigger requirements align with the driving circuit capabilities, noting the 35 mA maximum gate trigger current specification.

Part Context

This Triac belongs to the T16MxxT800UB series from Diodes Incorporated, designed for general-purpose AC switching applications. It shares the same physical package and core electrical ratings as the T16M10T800UB variant, differing primarily in gate sensitivity specifications. The series is intended for robust industrial and consumer electronics environments requiring reliable phase angle or on/off control.

Replacement Considerations

The T16M10T800UB is a direct functional substitute within the same product family, sharing identical voltage, current, and package specifications. When replacing components, verify that the alternative part meets the same thermal and electrical constraints defined in the original design specifications.
