T410-700T

Overview

The T410-700T is a logic-level sensitive gate TRIAC manufactured by STMicroelectronics, designed for AC switching applications. It features a peak repetitive off-state voltage of 700 V and an RMS on-state current rating of 4 A. The device operates within a junction temperature range of -40°C to 125°C and is housed in a TO-220 package. Key electrical parameters include a maximum gate trigger current (Igt) of 10 mA, a maximum gate trigger voltage (Vgt) of 1.3 V, and a holding current (Ih) of 15 mA. Non-repetitive surge currents are rated at 30 A for 50 Hz and 31 A for 60 Hz frequencies.

Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to ensure correct packaging and variant selection. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows. Cross-reference datasheet revisions to validate parameter consistency with current manufacturing standards.

Selection Notes

Select this component when designing circuits requiring logic-level triggering capabilities for AC load control. Ensure the 700 V blocking voltage exceeds the peak line voltage plus transient spikes. Verify that the 4 A RMS current rating accommodates the steady-state load requirements while accounting for thermal dissipation constraints inherent to the TO-220 package geometry.

Part Context

This part belongs to the T4 series of Snubberless TRIACs from STMicroelectronics. The series utilizes advanced silicon technology to provide high commutation performance without external snubber networks. These devices are engineered specifically for demanding AC switching environments where reliability and simplified circuit design are critical priorities.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic TRIAC replacements may lack the specific logic-gate sensitivity or Snubberless characteristics required for direct pin-to-pin compatibility without circuit modification.
