Overview
The STMicroelectronics T1610T-8I is a logic-level triac housed in a TO-220AB Insulated package. It supports an RMS on-state current of 16 A and a non-repetitive peak on-state current of 126 A. The device features a rated repetitive off-state voltage (VDRM) of 600 V and a maximum holding current of 25 mA. Gate triggering requires a voltage of 1.3 V and a current of 10 mA. Operating temperatures range from -40 °C to +150 °C, with an off-state leakage current of 5 µA at VDRM.
Feature Summary
- Logic level gate drive enabling direct microcontroller control with low gate current requirements.
- Tab-insulated package providing 2500 Vrms isolation between the tab and terminals.
- High static and dynamic commutation capabilities for reliable AC switching.
- Three-quadrant operation suitable for general-purpose AC power control applications.
Applications
- On/off or phase angle control functions in general purpose AC switching circuits.
- Direct driving by microcontrollers in resistive or small capacitive load systems.
- Industrial AC motor speed control and heating element regulation.
Procurement Notes
Verify the specific ordering suffix to confirm the insulated package variant and compliance status. Confirm RoHS and Ecopack2 grading against current regulatory requirements. Check datasheet revisions for any process change notifications that may affect mechanical dimensions or electrical parameters before finalizing procurement specifications.
Selection Notes
Select this component when high isolation voltage is required between the heatsink and circuit ground. The 16 A current rating suits moderate power AC loads. Ensure the gate driver can supply at least 10 mA to guarantee reliable triggering across the specified temperature range. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the target application.
Part Context
This part belongs to the T1610T series of triacs from STMicroelectronics. The 'I' suffix typically denotes the insulated package version, distinguishing it from standard TO-220 variants like the T1610T-8T. This series is designed for robust industrial applications requiring galvanic isolation and high thermal stability up to 150 °C junction temperature.
Replacement Considerations
Consider the T1610T-8T for non-isolated applications with identical electrical ratings. For higher voltage ratings, evaluate the T1612T series. Ensure substitute parts match the TO-220AB Insulated footprint if isolation is critical. Verify gate trigger current compatibility with existing driver circuits.
