Overview
The T3035H-6G is a bidirectional triac from STMicroelectronics, rated for 30 A RMS on-state current and 600 V repetitive peak off-state voltage. It operates within a junction temperature range of -40 °C to +150 °C and features a maximum non-repetitive surge current of 284 A. The device utilizes a TO-263 (D2PAK-3) surface-mount package with three pins. Key electrical parameters include a maximum gate trigger current of 35 mA, a maximum gate trigger voltage of 1 V, and an on-state voltage of 1.55 V. The component complies with RoHS standards.
Feature Summary
- Snubberless design based on high-temperature technology for enhanced noise immunity
- Robust dynamic turn-off commutation capabilities up to maximum junction temperatures
- Internal ceramic pad providing 2500 V RMS voltage insulation
Applications
- General purpose mains power AC switching
- Control of universal motors in industrial applications
- Heater and inductive load control for home appliances
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm exact package type and compliance status. Confirm that the requested variant matches the required voltage rating and thermal characteristics for the intended application environment before finalizing procurement orders.
Selection Notes
Select this component when designing compact surface-mount circuits requiring high thermal performance at elevated junction temperatures. The D2PAK package facilitates automated manufacturing and reduced heatsink sizes compared to traditional through-hole alternatives. Ensure the driving circuit can supply the specified gate trigger requirements for reliable commutation.
Part Context
This part belongs to the H-Series of Triacs designed specifically for operation at 150 °C. The series provides medium-current solutions suitable for heavy AC loads. The T3035H-6G variant specifically addresses the need for 600 V blocking capability in a surface-mount form factor, distinguishing it from higher voltage or lower current siblings in the same family.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative devices by matching critical parameters such as RMS current, blocking voltage, package dimensions, and thermal resistance specifications.
