T2035H-6G

Overview

The STMicroelectronics T2035H-6G is a medium current Triac from the H-Series, rated for 20 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 utilizes a D2PAK-3 surface mount package. Key electrical parameters include a maximum gate trigger current (Igt) of 35 mA, a maximum gate trigger voltage (Vgt) of 1 V, and a holding current (Ih) of 35 mA. The device supports a non-repetitive surge current of 210 A and exhibits an on-state voltage of 1.5 V with a leakage current of 5 µA at VDRM.

Feature Summary

• Snubberless technology enables high noise immunity and robust dynamic turn-off commutation without external RC snubbers.
• Internal ceramic pad provides 2500 V RMS voltage insulation between the case and terminals.
• High thermal performance allows for heatsink size reduction compared to traditional Triacs.
• Three triggering quadrant capability ensures reliable switching in various gate signal polarities.

Applications

• General purpose mains power AC switching
• Motor control drives for home appliances
• Heater load control in industrial environments

Procurement Notes

Verify the specific suffix 'G' confirms the D2PAK surface mount package and 600 V rating. Confirm RoHS compliance status and UL certification file E81734 relevance for your region. Ensure the ordering quantity matches the tray packaging requirements specified by the distributor. Check for any recent PCN updates regarding material or process changes.

Selection Notes

Select this component when a 20 A RMS current rating and 600 V blocking voltage are required in a compact SMD form factor. The 150 °C junction temperature capability makes it suitable for applications demanding reduced heatsink sizes. Verify that the 35 mA gate drive current aligns with your control circuit capabilities. Consider the TO-220AB insulated variant if through-hole mounting is preferred instead.

Part Context

The T2035H-6G belongs to STMicroelectronics' H-Series Triacs, designed for high-temperature operation up to 150 °C. This series integrates Snubberless technology to simplify circuit design by eliminating external snubber components. The device is part of a broader family offering various current ratings and voltage levels in both through-hole and surface mount packages.

Replacement Considerations

Direct substitutes within the same series include T2035H-6I (TO-220AB package) for equivalent electrical performance in a different footprint. Other H-Series variants may offer higher current ratings but require verification of pinout and thermal characteristics.
