Overview
The TIC246M-S is a silicon triac from the TIC246 series manufactured by Bourns Inc. It features a glass-passivated wafer and operates in a TO-220 package with through-hole mounting. The device supports a repetitive peak off-state voltage (VDRM) of 600 V and conducts a full-cycle RMS on-state current (IT(RMS)) of 16 A at case temperatures at or below 70°C. Peak on-state surge current (ITSM) reaches 125 A under resistive load conditions. Maximum gate trigger current (IGT) is specified at 50 mA for quadrants 1 through 3. Operating case temperature ranges from -40°C to +110°C, with storage limits extending to -40°C to +125°C.
Feature Summary
- Glass-passivated wafer construction for enhanced reliability
- High switching capability with 125 A peak surge current rating
- Robust commutation performance with critical dv/dt ratings up to 400 V/µs
Applications
- General purpose mains power AC switching
- Solid state relays
- Motor speed control circuits
Procurement Notes
Verify component authenticity against official Bourns datasheets before integration. Confirm that the specific suffix matches the required voltage rating. Check for obsolescence status as this series may be restricted for new designs. Ensure thermal management meets the derating requirements above 70°C case temperature.
Selection Notes
Select based on the 600 V off-state voltage requirement and 16 A continuous current capacity. Consider the TO-220 package for adequate heat dissipation without excessive heatsinking. Verify gate drive compatibility with the 50 mA maximum trigger current specification across all operating quadrants.
Part Context
This component belongs to the TIC246 series of high-current silicon triacs. The series offers multiple voltage variants ranging from 400 V to 800 V. The TIC246M-S specifically denotes the 600 V version within this family, sharing common thermal and electrical characteristics with other members like the TIC246D and TIC246S.
Replacement Considerations
Direct substitutes include other 600 V, 16 A TRIACs in TO-220 packages such as the TIC226M-S. Verify pinout compatibility and thermal resistance values when cross-referencing with alternative manufacturers' components.
FAQ
What is the maximum gate trigger current for the TIC246M-S?
The maximum gate trigger current (IGT) is 50 mA for quadrants 1 through 3.
How does the RMS current rating change with temperature?
The 16 A rating applies at or below 70°C case temperature. Above 70°C, the current must be derated linearly to 110°C at a rate of 400 mA per degree Celsius.
Is the TIC246M-S recommended for new designs?
No, the datasheet states that while the series is available, it is not recommended for new designs.
