T1235H-600G

Triacs Overview

The T1235H-600G is a Snubberless high temperature triac designed for hot appliance applications. It features an RMS on-state current of 12 A and a repetitive peak off-state voltage of 600 V. The device operates within a junction temperature range of -40 to +150 °C. Key electrical parameters include a maximum gate trigger current of 35 mA, a minimum static dV/dt of 300 V/µs, and a critical rate of rise of on-state current of 50 A/µs at 150 °C. The non-repetitive surge peak on-state current reaches 140 A at 50 Hz. Thermal resistance from junction to case is 1.2 °C/W in the D2PAK package.

Triacs Feature Summary

• Snubberless technology enables direct switching of inductive loads without external RC snubber circuits.
• High temperature design supports operation up to 150 °C junction temperature for use in hot appliances.
• Clip assembly technique provides superior performance in handling surge currents.

Triacs Applications

• General purpose mains power AC switching
• Static relays and heating regulation
• Induction motor starting circuits
• Phase control operations in light dimmers

Triacs Procurement Notes

Verify the specific ordering suffix to confirm the packing mode. The standard tube version uses the suffix G, while the tape and reel variant requires the -TR suffix. Confirm that the component meets RoHS compliance standards as specified in the ECOPACK package description before finalizing procurement orders.

Triacs Selection Notes

Select this component when designing systems requiring high thermal stability and robust commutation capabilities. Ensure the application circuit respects the 50 A/µs critical rate of rise limit at elevated temperatures. Verify that the copper surface area under the tab meets the thermal requirements for the expected ambient conditions.

Triacs Part Context

This part belongs to the T12xxH Triac series, which includes variants like the T1235H-600T. The series utilizes internal ceramic pads for insulation and is suitable for general-purpose AC switching. The T1235H-600G specifically denotes the D2PAK surface mount package configuration.

Triacs Replacement Considerations

The T1235H-600T serves as a through-hole alternative with identical electrical characteristics but housed in a TO-220AB package. Designers must account for the different thermal resistance values and physical mounting requirements when substituting between these package types.
