Optimized Thermal and Mechanical Design
Housed in a compact TO-220 package, the T835H-6I combines excellent thermal dissipation with through-hole mounting convenience. Its operating temperature range of -40°C to 150°C ensures reliable performance in industrial environments with extreme temperature variations. The single-component configuration simplifies PCB layout while maintaining mechanical stability in vibration-prone applications.
This TRIAC's Snubberless™ architecture represents a significant advancement in power semiconductor design. By integrating protective circuitry directly into the die structure, STMicroelectronics has eliminated traditional external snubber networks composed of resistors and capacitors. This innovation reduces component count, lowers manufacturing costs, and improves long-term reliability by minimizing potential failure points.

The T835H-6I excels in applications requiring precise AC power control, including:
- Industrial motor drives and variable speed systems
- Heating control for industrial ovens and process equipment
- Power factor correction circuits
- Lighting control systems with dimming capabilities
- Appliance motor control in HVAC systems
Its ability to handle high inrush currents makes it particularly suitable for controlling inductive loads such as motors and transformers. The device's inherent immunity to false triggering ensures stable operation in electrically noisy environments common in industrial settings.
Comprehensive Protection Features
Beyond its basic switching capabilities, the T835H-6I incorporates multiple protection mechanisms that enhance system reliability:
- Integrated overvoltage protection through built-in snubber technology
- Thermal runaway prevention through optimized die design
- High immunity to dv/dt-induced false triggering
- Robust short-circuit protection through current limiting characteristics
These features make the device particularly well-suited for safety-critical applications where unexpected failures could compromise system operation or personnel safety.
Environmental Compliance and Packaging
Built to meet modern environmental standards, the T835H-6I complies with RoHS directives and is manufactured using STMicroelectronics' eco-conscious processes. The device is available in standard tube packaging, facilitating automated pick-and-place assembly while maintaining component integrity during storage and handling.
