T835-800B-TR

Overview

The STMicroelectronics T835-800B-TR is a Snubberless Triac rated for 8 A RMS on-state current and 800 V repetitive peak off-state voltage. It operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The device exhibits a typical on-state voltage of 1.55 V and a non-repetitive peak surge current capacity of 80 A. It is housed in a DPAK (TO-252-3) surface-mount package.

Feature Summary

Snubberless design eliminates the need for external RC snubber circuits across inductive loads
High static dV/dt provides robust immunity against false triggering from voltage transients
Robust dynamic turn-off commutation capability ensures reliable operation under demanding load conditions

Applications

General purpose AC switching applications
Static relay control circuits
Heating regulation systems

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration required for automated assembly processes. Confirm RoHS compliance status and moisture sensitivity level prior to procurement to ensure compatibility with standard manufacturing handling procedures.

Selection Notes

Select this component when high commutation performance is required for inductive loads without external snubbers. Ensure the application voltage does not exceed the 800 V rating and that the gate drive circuit can supply at least 35 mA to guarantee reliable triggering across the specified temperature range.

Part Context

This part belongs to the T835 series of Snubberless Triacs manufactured by STMicroelectronics. The series includes variants in DPAK, D2PAK, and TO-220 packages with varying voltage ratings. The T835-800B-TR specifically denotes the 800 V version in the DPAK package supplied in a tape and reel format.
