Overview
The T1620T-6I is a Snubberless Triac from STMicroelectronics designed for general-purpose AC switching applications. It operates with a rated repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 16 A. The device supports a non-repetitive peak on-state current of 140 A and features a maximum on-state voltage of 1.55 V. It functions within a temperature range of -40 °C to +125 °C and utilizes a TO-220AB insulated package providing 2500 Vrms isolation.
Feature Summary
- Snubberless design eliminates the need for external RC networks when datasheet limits are respected
- High static and dynamic commutation capabilities ensure reliable switching performance
- Insulated package provides 2500 Vrms isolation for enhanced safety in mains power applications
Applications
- On/off or phase angle control function in general purpose AC switching
- Light dimmers and lighting control systems
- Motor speed control circuits
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number and date code against official STMicroelectronics documentation. Ensure the specific ordering suffix matches the required insulation and packaging specifications. Confirm RoHS compliance status through the latest product information sheet before finalizing procurement orders.
Selection Notes
Select this component for designs requiring high commutation capability without snubber circuits. The insulated package is suitable for applications needing galvanic isolation between the heatsink and circuit ground. Verify that the gate trigger requirements align with the driving logic levels and that the thermal management strategy accommodates the specified junction temperature limits.
Part Context
This device belongs to the T12T series of Triacs, which are optimized for value-sensitive appliances. The series offers medium current handling with low thermal resistance due to clip bonding technology. These components are UL certified and compliant with RoHS directives, supporting efficient system development processes through standardized design parameters.
Replacement Considerations
Direct replacements must match the 16 A current rating, 600 V blocking voltage, and TO-220AB insulated package configuration. Verify that alternative devices offer comparable static dv/dt and dynamic turn-off commutation capabilities to maintain snubberless operation integrity.
