T1605G-6I

Triacs Overview

The T1605G-6I is a logic level triac in an insulated TO-220AB package, rated for 16 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a super low holding current of 5 mA and a maximum gate trigger current of 5 mA. The device supports three-quadrant triggering with a maximum gate trigger voltage of 1.3 V. Operating junction temperature ranges from -40 °C to +125 °C, with a non-repetitive surge peak on-state current of 140 A at 25 °C. Thermal resistance from junction to case is typically 2.1 °C/W.

Triacs Procurement Notes

Verify the specific ordering code T1605G-6I against the manufacturer's official documentation to ensure correct package type and electrical ratings. Confirm compliance requirements such as RoHS and halogen-free status directly with the supplier or original datasheet before procurement.

Triacs Selection Notes

Select this component for general purpose AC switching applications requiring high commutation capability. The low holding current makes it suitable for deep dimming in LED applications without flickering. Ensure the circuit design respects the 600 V blocking voltage and 16 A RMS current limits under specified thermal conditions.

Triacs Part Context

This part belongs to the T16xxG series of logic level triacs designed specifically for lighting applications. The 'G' suffix indicates the Light Dimmer Triac series, while '6I' specifies the 600 V blocking voltage and TO-220AB Insulated package configuration within the STMicroelectronics product lineup.

Triacs Replacement Considerations

Consult official substitution lists for equivalent triacs with matching 16 A current, 600 V voltage, and TO-220AB Insulated packages. Verify that any replacement maintains the 5 mA holding current and logic level gate trigger specifications for compatibility with existing control circuits.
