Overview
The Bourns TIC246N-S is a silicon triac from the TIC246 series, rated for 800 V repetitive peak off-state voltage and 16 A RMS on-state current. It features a TO-220 package with glass-passivated wafer construction. The device supports a peak surge current of 125 A and operates within a case temperature range of -40°C to +110°C. Key electrical characteristics include a maximum gate trigger current of 50 mA across quadrants 1 through 3, an on-state voltage of typically 1.7 V at 22.5 A, and a critical rate of rise of off-state voltage of ±400 V/µs. Junction-to-case thermal resistance is specified at 1.9 °C/W.
Feature Summary
- Glass-passivated wafer construction for enhanced reliability
- High current handling capability with 16 A RMS rating
- Robust triggering performance with low gate current requirements
Applications
- Industrial motor control systems
- Solid-state relays
- Power regulation circuits
Procurement Notes
Verify component authenticity by cross-referencing the part number against official manufacturer documentation. Confirm that the specific suffix matches the required voltage rating. Check for obsolescence status as this series may be restricted for new designs. Ensure sourcing channels provide valid traceability records for quality assurance purposes.
Selection Notes
Select the TIC246N-S variant specifically when an 800 V blocking voltage is required. Compare thermal management needs against the junction-to-case resistance. Evaluate gate drive capabilities to ensure they meet the 50 mA trigger threshold. Consider derating factors for operating temperatures above 70°C to maintain safe current levels.
Part Context
This component belongs to the TIC246 series of high-current silicon triacs manufactured by Bourns. The series offers multiple voltage ratings including 400 V, 600 V, and 700 V variants. The TIC246N-S represents the highest voltage option in this specific lineup, designed for demanding power switching applications requiring robust off-state blocking capabilities.
Replacement Considerations
Consult official substitution guides for equivalent triacs with matching 16 A and 800 V ratings. Verify pinout compatibility for TO-220 packages before implementation.
