T1635-700G-TR

Triacs Overview

The T1635-700G-TR is a Snubberless™ logic standard TRIAC manufactured by STMicroelectronics, designed for surface mount applications in the D2PAK package. It features an RMS on-state current of 16 A and a non-repetitive peak on-state current of 168 A. The device supports a rated repetitive off-state voltage (VDRM) of 700 V with a maximum off-state leakage current of 5 uA at VDRM. Key electrical parameters include an on-state voltage of 1.55 V, a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. The component operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Snubberless design enables direct switching of inductive loads without external snubber circuits, provided datasheet limits are respected.
• Logic level compatibility allows direct interfacing with low-power drivers such as microcontrollers.
• High commutation capability ensures reliable turn-off performance in three quadrants for demanding AC load control.

Triacs Applications

• General purpose AC switching and static relays
• Heating regulation systems
• Induction motor start circuits and speed controllers

Triacs Procurement Notes

Verify the specific suffix G-TR against official STMicroelectronics documentation to confirm the D2PAK surface mount package and reel packaging configuration. Ensure the procurement channel provides valid RoHS compliance certificates and original manufacturer traceability. Cross-reference the part number with authorized distributor databases to validate authenticity and avoid counterfeit components during acquisition.

Triacs Selection Notes

Select this component when a 16 A RMS current rating and 700 V blocking voltage are required for AC load control. The D2PAK package is suitable for surface mount assembly where thermal management via the exposed tab is necessary. Consider the 1.3 V gate trigger voltage for compatibility with standard logic-level drive signals in industrial or appliance control environments.

Triacs Part Context

This device belongs to the T1635 series of Snubberless™ TRIACs from STMicroelectronics. The series includes variants with different voltage ratings, such as 600 V and 800 V versions, all sharing the same 16 A current handling capability and D2PAK form factor. The T1635-700G-TR specifically targets applications requiring intermediate voltage blocking capabilities within this standardized product family.

Triacs Replacement Considerations

Compatible substitutes within the same series include T1635-600G-TR for lower voltage requirements and T1635-800G-TR for higher voltage tolerance. Both maintain identical current ratings and package dimensions, allowing for pin-compatible replacement if the circuit voltage headroom permits adjustment.
