TIC201S-S

Overview

The Bourns TIC201S-S is a silicon triac from the TIC201 series, featuring a glass-passivated wafer and sensitive gate design. It offers a maximum repetitive peak off-state voltage (VDRM) of 700 V and supports a full-cycle RMS on-state current (IT(RMS)) of 2.5 A at case temperatures up to 85°C. The device handles a peak on-state surge current (ITSM) of 12 A under resistive load conditions. Electrical characteristics include a maximum gate trigger current (IGT) of 5 mA in Quadrant I operation and an on-state voltage (VT) of ±1.9 V at ±3.5 A. Thermal resistance from junction to case is 10 °C/W, with an operating case temperature range spanning -40°C to +110°C.

Feature Summary

• Sensitive gate architecture enabling reliable triggering with low gate current requirements.
• Glass passivation provides enhanced environmental protection for the silicon wafer.
• Bidirectional control capability suitable for AC power switching applications.

Applications

• AC motor speed control circuits
• Solid-state relay output stages
• Lighting dimmer switches

Procurement Notes

Verify the specific suffix 'S' against the manufacturer's official documentation to confirm package type and marking details. Ensure the procurement source provides valid traceability data. Confirm that the component meets RoHS compliance standards if required by the application. Check for any obsolete status notifications or lifecycle changes directly from the manufacturer before finalizing orders.

Selection Notes

Select the TIC201S-S when a 700 V blocking voltage is required for AC line applications. Ensure the thermal management design accommodates the 10 °C/W junction-to-case resistance. Verify that the gate drive circuit can supply sufficient current within the specified limits for reliable triggering across the full operating temperature range.

Part Context

The TIC201 series comprises silicon triacs designed for general-purpose AC power control. This family includes variants with different voltage ratings, such as 400 V and 600 V options. The TIC201S-S represents the highest voltage variant in this specific series configuration, offering robust performance for medium-power industrial and consumer electronics applications requiring precise phase control.

Replacement Considerations

Consult official substitution guides for equivalent triacs with matching 700 V ratings and TO-220 packaging. Verify pinout compatibility and thermal characteristics before implementing any alternative components in existing designs.
