T1620T-8G

Triacs Overview

The T1620T-8G is a Snubberless Triac in the D²PAK surface-mount package, rated for 16 A RMS on-state current and 800 V repetitive peak off-state voltage. It supports three-quadrant triggering with a maximum gate trigger current of 20 mA and voltage of 1.3 V. The device features high static dV/dt immunity (minimum 1000 V/µs at 125 °C) and dynamic turn-off commutation capability up to 100 A/µs. Operating junction temperature ranges from -40 °C to +150 °C, with a non-insulated tab providing a thermal resistance of 1.15 °C/W.

Triacs Feature Summary

• Snubberless design allows operation without external RC circuits when datasheet limits are respected
• High static dV/dt provides strong immunity against false turn-on events
• Extended thermal margin enabled by 150 °C maximum junction temperature rating
• Non-insulated tab construction ensures efficient heat dissipation

Triacs Applications

• General purpose AC line load switching
• Motor control circuits
• Home appliances
• Heating systems
• Lighting controls

Triacs Procurement Notes

Verify the specific ordering suffix during acquisition. The base part number corresponds to tube packaging, while the -TR suffix indicates tape and reel delivery. Confirm that the procurement source matches the required physical configuration for your assembly process.

Triacs Selection Notes

Select this component for applications requiring high commutation capability in general-purpose AC switching. Ensure the circuit design respects the defined snubberless limits to utilize the device's full potential. Verify that the gate drive circuit can supply the specified 20 mA trigger current across the operating temperature range.

Triacs Part Context

This device belongs to STMicroelectronics' T-Series Triacs, which are optimized for high EMI constraints and general-purpose AC switching. The T1620T-8G variant specifically targets applications needing robust performance in high-temperature environments with simplified circuit requirements due to its integrated snubberless characteristics.

Triacs Replacement Considerations

The T1620T-8I serves as a through-hole alternative within the same series. When substituting, verify that the new package type accommodates the existing PCB layout and that the electrical ratings remain compatible with the application requirements.
