Overview
The T3035H-6T is a 30 A, 600 V H-series Triac manufactured by STMicroelectronics. It utilizes Snubberless technology to ensure high noise immunity and specified turn-off commutation capabilities up to a maximum junction temperature of 150 °C. The device features a TO-220AB through-hole package with an internal ceramic pad providing 2500 V RMS voltage insulation. Key electrical parameters include a maximum on-state current (ItRMS) of 30 A, a non-repetitive peak surge current (Itsm) of 284 A at 50/60 Hz, and a maximum gate trigger current (Igt) of 35 mA.
Feature Summary
- Snubberless design for simplified circuit implementation
- High thermal performance allowing operation up to 150 °C
- Internal ceramic pad for enhanced voltage insulation
Applications
- Control of universal motors in power tools
- Inductive load switching in major home appliances
- Industrial control systems requiring robust AC switching
Procurement Notes
Verify the specific suffix '6T' against official datasheets to confirm the 600 V rating and TO-220AB package configuration. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement. Cross-reference manufacturer part numbers to avoid confusion with surface mount variants like the T3035H-6G.
Selection Notes
Select this component when designing circuits that require high current handling up to 30 A and operate in environments with significant electrical noise. The 150 °C junction temperature capability allows for reduced heatsink sizes compared to standard Triacs. Verify that the application does not exceed the 284 A surge current limit during startup or fault conditions.
Part Context
This part belongs to the ST H-series Triac family, which is engineered for high-temperature operation and robust commutation. The T3035H-6T specifically addresses the need for reliable AC switching in compact designs where traditional solutions might require larger heat sinks. It is distinct from lower current variants and higher voltage versions within the same series.
Replacement Considerations
The Q6035RH5TP from Littelfuse Inc. is listed as a substitute option. Verify pinout compatibility and exact electrical parameter matching before substitution.
