TIC253D-S

Overview

The Bourns TIC253D-S is a silicon triac rated for 400 V repetitive peak off-state voltage and 20 A RMS on-state current. It features a glass-passivated wafer and operates within a case temperature range of -40°C to +110°C. The device supports a peak surge current of 150 A and has a maximum gate trigger current of 50 mA across quadrants 1 through 3. Packaged in an SOT-93 outline, it includes a mounting base electrically connected to pin 2. Thermal resistance from junction to case is specified at 1.52 °C/W.

Feature Summary

Glass-passivated silicon construction for enhanced reliability
Integrated mounting base with electrical connection to pin 2
High surge current capability for robust circuit protection

Applications

AC power control circuits
Solid-state relays
Motor speed control systems

Procurement Notes

Verify the specific suffix 'S' confirms the 400V rating variant during procurement. Confirm package compatibility with standard SOT-93 footprints. Ensure thermal management design accounts for the specified junction-to-case resistance. Validate that operating conditions remain within the defined temperature limits.

Selection Notes

Select this component when a 400V blocking voltage is required alongside high current handling. Compare against higher voltage variants if system transients exceed 400V. Consider the SOT-93 package constraints for PCB layout. Evaluate thermal dissipation requirements based on the 20A RMS rating and ambient conditions.

Part Context

This part belongs to the TIC253 series of high-current silicon triacs. The series offers multiple voltage ratings including 600V, 700V, and 800V options. All variants share similar current ratings and packaging characteristics. The series is designed for general-purpose AC switching applications requiring reliable performance.

Replacement Considerations

Check for direct cross-reference availability from other manufacturers offering equivalent SOT-93 triacs with matching 400V and 20A specifications. Verify pinout compatibility and thermal resistance values before substitution.
