T1235H-600G-TR

Triacs Overview

The T1235H-600G-TR is a high-temperature Snubberless triac from STMicroelectronics, rated for 12 A RMS on-state current and 600 V blocking voltage. Housed in a D2PAK surface-mount package, it operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum gate trigger current (IGT) of 35 mA, a peak on-state voltage of 1.55 V at 17 A, and a non-repetitive surge current capability of 140 A at 50 Hz. The device features a thermal resistance (junction-to-case) of 1.2 °C/W and complies with ECOPACK environmental standards.

Triacs Feature Summary

• Snubberless technology provides high commutation switching capabilities and noise immunity without external RC networks.
• Clip assembly technique ensures superior performance in handling surge currents.
• Optimized for enhanced power loss reduction and thermal dissipation in high-temperature environments.

Triacs Applications

• Control of AC loads in hot appliances such as cookers, ovens, hobs, electric heaters, and coffee machines.
• Industrial control systems requiring robust AC switching under high thermal stress.
• Compact drive applications for universal motors and inductive loads where heatsink size reduction is critical.

Triacs Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the tape-and-reel packaging configuration. Ensure that the component selection aligns with the required thermal management strategy for the target application environment. Cross-reference the part number with the latest datasheet revision history to confirm compliance with current manufacturing standards.

Triacs Selection Notes

Select this component when designing circuits for high-temperature operation up to 150°C junction temperature. The D2PAK package is suitable for surface-mount designs or insulated metal substrate boards. Consider the 1.2 °C/W thermal resistance for heatsinking calculations. Verify that the 35 mA gate trigger current matches the driving circuit capabilities for reliable turn-on across all quadrants.

Triacs Part Context

This device belongs to the T1235H series of medium-current triacs designed specifically for mains power AC switching in demanding thermal conditions. It utilizes ST's proprietary Snubberless technology to simplify circuit design by eliminating the need for external snubber components. The series includes variants for different voltage ratings and packages, offering flexibility for various industrial and home appliance applications.

Triacs Replacement Considerations

Direct substitutes within the same family include the T1235H-600G (tube packaging). For through-hole requirements, the T1235H-600T in a TO-220AB package offers equivalent electrical characteristics. Ensure any replacement maintains the 12 A current rating and 600 V blocking voltage specifications.
