T1620-700W

Triacs Overview

The T1620-700W is a Snubberless Triac from STMicroelectronics rated for 700V blocking voltage and 16A RMS current. It utilizes proprietary Snubberless technology to ensure high commutation performance without external RC networks. The device features a non-latching gate structure for reliable triggering. Key electrical parameters include a maximum on-state voltage of 1.6V, a holding current of 40mA, and a gate trigger current of 20mA. It operates within a temperature range of -40°C to +125°C and is housed in an ISOWATT package.

Triacs Feature Summary

• Snubberless technology eliminates the need for external snubber circuits
• High commutation performance with dV/dt rating of 300 V/µs
• Non-latching gate structure ensures reliable turn-off
• RoHS compliant construction

Triacs Applications

• Industrial motor control systems
• Solid state relays
• Lighting dimmers
• Heating control applications

Triacs Procurement Notes

Verify the specific voltage variant (600W, 700W, or 800W) required for the circuit design, as the T1620 series includes multiple ratings. Confirm package availability, as TO-220 variants may differ from surface-mount options. Ensure compliance with local RoHS directives before finalizing procurement orders.

Triacs Selection Notes

Select this component when high commutation capability is needed without adding passive snubber components. The 700V rating suits medium-voltage AC switching applications. Compare against the T1630 series if higher current capacity is required. Verify thermal management requirements for the TO-220 package in enclosed environments.

Triacs Part Context

This part belongs to the T1620T/T1620W Snubberless Triac family. It shares functional characteristics with the T1620-600W and T1620-800W models, differing primarily in repetitive peak off-state voltage. The series is designed for general-purpose AC power control where reliability and simplified circuit topology are priorities.

Triacs Replacement Considerations

Direct substitutes include other STMicroelectronics Snubberless Triacs such as the T1620-600W or T1620-800W, provided the voltage rating meets the application's peak line voltage requirements. Cross-brand replacements require verification of dV/dt ratings and gate trigger characteristics.
