TIC206D-S

Overview

The TIC206D-S is a four-quadrant logic level TRIAC manufactured by Bourns Inc. It features a peak repetitive off-state voltage of 400V and an RMS on-state current rating of 1.5A. The device is housed in a TO-92 package with three pins. Designed for low-power switching applications, it integrates gate drive circuitry to allow direct interfacing with digital logic families without requiring external isolation components.

Feature Summary

• Four-quadrant sensitivity enables reliable triggering across all AC line polarities
• Logic-level gate interface allows direct connection to standard TTL or CMOS outputs
• Compact TO-92 cylindrical plastic package facilitates through-hole mounting

Applications

• Low-power light dimming circuits
• Small motor speed control systems
• Thermostat heating element regulation

Procurement Notes

Verify the specific suffix 'S' against the official Bourns datasheet to confirm packaging details such as tape-and-reel specifications or lead finish variations. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a compact TRIAC is required for currents up to 1.5A RMS. The 400V voltage rating suits low-voltage AC applications. Consider the TO-92 package constraints regarding thermal dissipation compared to larger packages like TO-220. Verify that the logic-level gate trigger characteristics match the driving microcontroller or logic family voltage levels.

Part Context

This device belongs to the TIC series of logic-level TRIACs from Bourns. It shares functional similarities with other models in the lineup but differs in voltage and current ratings. The TIC206D-S specifically targets applications needing moderate power handling in a small form factor, distinguishing it from higher-current variants or lower-voltage alternatives within the same product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate equivalent logic-level TRIACs with matching 400V V(DRM) and 1.5A I(T)RMS ratings in TO-92 packages from other manufacturers only after verifying pinout compatibility and electrical specifications.
