TIC206M-S

Overview

The TIC206M-S is a silicon triac manufactured by Bourns Inc., housed in a TO-220AB package. It is rated for a maximum repetitive peak off-state voltage of 600V and an RMS on-state current of 4A. This component features four-quadrant logic level triggering, allowing it to be driven directly from TTL or CMOS logic circuits without requiring additional buffer components. The device is designed for general-purpose AC power control applications.

Feature Summary

• Four-quadrant logic level triggering capability for direct interface with standard digital logic families
• High thermal stability and robust construction suitable for industrial environments
• Isolated case configuration for easy mounting to heat sinks

Applications

• Solid state relays
• AC motor speed controls
• Lighting dimmers

Procurement Notes

Verify the specific manufacturer source when ordering, as multiple vendors produce this part number. Confirm that the suffix '-S' corresponds to the intended packaging variant, typically indicating a specific tape and reel or bulk option depending on the supplier's catalog. Ensure the datasheet matches the required electrical ratings for your design.

Selection Notes

Select this component when a 4A RMS current rating and 600V blocking voltage are sufficient for the load. The logic-level gate sensitivity simplifies driver circuit design compared to standard TRIACs. Consider the thermal resistance of the TO-220AB package and ensure adequate heatsinking if operating near the maximum current limit.

Part Context

The TIC206M-S belongs to the TIC20x series of logic-level TRIACs from Bourns. This series is widely used in consumer and industrial appliances where compact AC switching is required. The 'S' suffix often denotes a specific packaging style, such as a shrink-wrap or specific bulk configuration, distinct from the standard TIC206M.

Replacement Considerations

Direct replacements include the TIC206M from other manufacturers like Texas Instruments or New Jersey Semiconductor, provided the pinout and electrical ratings match. Verify that substitute parts also offer four-quadrant logic triggering to maintain compatibility with existing drive circuits.
