TIC236D-S

Overview

The Bourns TIC236D-S is a silicon TRIAC from the TIC236 series, rated for 12 A RMS on-state current and a repetitive peak off-state voltage of 400 V. It features a glass-passivated wafer construction and operates within an ambient temperature range of -40°C to +110°C. The device supports a maximum gate trigger current of 50 mA across quadrants 1 through 3. Electrical characteristics include a typical on-state voltage of 2.1 V at 17 A and a critical rate of rise of on-state current of 100 A/µs. Thermal resistance from junction to case is specified at 2°C/W.

Feature Summary

• Glass-passivated wafer construction for enhanced durability
• High current handling capability with 12 A RMS rating
• Sensitive gate triggering with a maximum IGT of 50 mA

Applications

• General purpose AC power control circuits
• Solid state relays
• Motor speed control applications

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer marking code against official Bourns documentation. Confirm the specific suffix designation matches the required voltage rating, as the TIC236 series includes variants with different off-state voltages. Ensure compliance with relevant RoHS directives if applicable to the manufacturing batch.

Selection Notes

Select this component when a 400 V blocking voltage is sufficient for the application. Consider thermal management requirements given the 2°C/W junction-to-case resistance. Evaluate the 50 mA gate trigger current requirement against the driving circuit capabilities to ensure reliable switching under all operating conditions.

Part Context

The TIC236D-S belongs to the broader TIC236 series of high-current silicon TRIACs manufactured by Bourns. This family includes variants with higher voltage ratings, such as the TIC236M (600 V), TIC236S (700 V), and TIC236N (800 V). All series members share identical current ratings and package configurations.

Replacement Considerations

Direct replacements must match the 400 V off-state voltage and 12 A RMS current rating. Verify that alternative TRIACs possess compatible gate trigger characteristics and thermal resistance values to ensure seamless integration without redesigning the heat sinking or drive circuitry.
