T1620-600W

Triacs Overview

The T1620-600W is a 16A Snubberless Triac rated for 600V in an ISOWATT220AB package. It features a maximum RMS on-state current of 16A at 80°C case temperature and supports non-repetitive surge peak currents up to 200A at 50Hz. The device operates within a junction temperature range of -40°C to +125°C, with a storage range of -40°C to +150°C. Key electrical parameters include a gate trigger current (IGT) maximum of 20mA, holding current (IH) maximum of 35mA, and a critical rate of rise of on-state current ((dI/dt)c) minimum of 8.5 A/µs at 125°C. Thermal resistance from junction to case is 3.1°C/W.

Triacs Feature Summary

• Based on ST's Snubberless technology providing high commutation performances
• Specially recommended for use on inductive loads such as vacuum cleaners and heating regulation
• Complies with UL standards

Triacs Applications

• Inductive load switching
• Vacuum cleaner control
• Heating regulation systems

Triacs Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compatibility with your design requirements. Confirm that the ISOWATT220AB package dimensions and thermal characteristics meet your system constraints. Check for any updates to the datasheet or compliance certifications before finalizing procurement decisions.

Triacs Selection Notes

Select this component for applications requiring high commutation performance on inductive loads. Ensure the operating junction temperature does not exceed 125°C. Consider the 20mA gate trigger current when designing the drive circuit. Verify that the 600V rating is sufficient for the peak off-state voltage in your AC mains application.

Triacs Part Context

This component belongs to the T1620 series of Snubberless Triacs manufactured by STMicroelectronics. It is part of a family that includes variants with different voltage ratings (600V and 800W) and gate sensitivities (20mA and 30mA). The T1620-600W specifically offers a balance of current handling and voltage blocking capability in an insulated TO-220 style package.

Triacs Replacement Considerations

Direct replacements include the T1620-800W for higher voltage tolerance, or the T1630-600W if a higher gate trigger current of 30mA is acceptable. Ensure the replacement maintains the same ISOWATT220AB package for mechanical compatibility.
