T835-600B

Overview

The STMicroelectronics T835-600B is an 8 A Snubberless Triac rated for a repetitive peak off-state voltage of 600 V. It features a maximum on-state voltage of 1.55 V and a gate trigger current of up to 35 mA. The device supports a non-repetitive surge current of 80 A and operates within a junction temperature range of -40 °C to +150 °C. Packaged in DPAK (TO-252-3) for surface mount applications, it offers low thermal resistance and high static dV/dt capability.

Feature Summary

• Snubberless design eliminates the need for external RC snubber circuits on inductive loads
• Logic level interface allows direct connection to microcontrollers and low power drivers
• High static and dynamic commutation performance ensures reliable switching

Applications

• General purpose AC switching
• Static relays
• Heating regulation systems
• Light dimmers
• Motor speed controllers

Procurement Notes

Verify the specific suffix 'B' against official STMicroelectronics documentation to confirm package type and electrical tolerances. Ensure the selected variant matches the required 600 V rating and 8 A RMS current for the intended circuit design before procurement.

Selection Notes

Select this component for applications requiring high commutation capability without external snubbers. Verify that the logic level triggering characteristics align with the driving circuit's output capabilities. Confirm the DPAK package thermal management meets the system's heat dissipation requirements.

Part Context

The T835 series belongs to STMicroelectronics' Snubberless Triac family, designed for value-sensitive appliances. These devices provide medium current handling with low thermal resistance clip bonding. The series includes both through-hole and surface-mount options to support diverse PCB layout needs.

Replacement Considerations

Check for other T835 variants with different voltage ratings or packages. Verify compatibility with equivalent Snubberless Triacs from other manufacturers if supply constraints exist.
