Overview
The STMicroelectronics T835-600G-TR is a Snubberless™ TRIAC in the T835 series, designed for general-purpose AC switching. It features an 8 A RMS on-state current and a 600 V repetitive peak off-state voltage. Packaged in a surface-mount TO-263 (D2PAK) housing with three pins, it supports a junction temperature range from -40°C to 125°C. Key electrical parameters include a maximum gate trigger current of 35 mA, a peak on-state voltage of 1.55 V, and a non-repetitive surge current rating of 84 A at 50/60 Hz. The device operates with a maximum holding current of 35 mA and exhibits a low off-state leakage current of 5 μA.
Feature Summary
- Snubberless design enables direct use on inductive loads without external RC snubber circuits when operating within defined limits.
- Logic level compatibility allows direct interfacing with low-power drivers such as microcontrollers.
- High static dV/dt immunity reduces the risk of false turn-on events during operation.
Applications
- Static relays requiring ON/OFF control functions
- Heating regulation systems
- Induction motor starting circuits
- Light dimmers utilizing phase angle control
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component for applications requiring high commutation capability on inductive loads. The logic-level gate drive simplifies interface design with digital controllers. Verify that the 600 V blocking voltage and 8 A current ratings exceed the circuit's maximum operational demands to ensure reliable performance.
Part Context
This device belongs to the STMicroelectronics T835 series of 8 A Snubberless TRIACs. The series includes variants with different voltage ratings and packages, such as the through-hole T835T-8I and the 800 V rated T835T-8G. The T835-600G-TR specifically utilizes the D2PAK surface-mount package for automated assembly.
Replacement Considerations
The T835-600G is a pin-compatible alternative available in standard packaging instead of tape and reel. Other series members like the T835T-8G offer higher voltage ratings but require verification of thermal and electrical compatibility.
