Overview
The TIC225S-S is a silicon Triac from the TIC225 series, manufactured by Bourns Inc. It features an 8 A RMS full-cycle on-state current and a peak surge current of 70 A. The device offers a repetitive peak off-state voltage (VDRM) of 700 V. It utilizes a TO-220 package with three pins, where Pin 2 connects to the mounting base. The gate trigger current (IGT) maximum is 5 mA in Quadrant I operation. Operating case temperature ranges from -40°C to +110°C, with storage temperatures up to +125°C. Junction-to-case thermal resistance is typically 2.5 °C/W.
Feature Summary
- Sensitive gate design enabling low power triggering requirements
- Glass passivated wafer construction for enhanced reliability
- High static and dynamic commutation capability
Applications
- General purpose AC switching
- On/off control functions
- Phase angle control applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolete status indicators as this part may be discontinued. Ensure proper handling procedures are followed during installation to maintain electrical integrity.
Selection Notes
Select based on required blocking voltage ratings and thermal management needs. Consider derating curves for operating temperatures above 70°C. Verify gate trigger characteristics match the driving circuit capabilities. Evaluate thermal resistance parameters for heat sink requirements in high-current scenarios.
Part Context
This component belongs to the TIC225 series of sensitive gate Triacs. The series includes variants with different voltage ratings such as 400 V, 600 V, and 800 V options. All members share similar current handling capabilities and package styles, designed for general AC switching applications requiring reliable performance.
Replacement Considerations
Check for equivalent Triacs with matching 700 V rating and 8 A current capacity. Verify pinout compatibility with TO-220 packages. Ensure gate sensitivity specifications align with existing drive circuits. Confirm thermal performance matches original design constraints.
FAQ
What is the maximum gate trigger current for the TIC225S-S?
The maximum gate trigger current (IGT) is 5 mA when operating in Quadrant I.
How does the on-state current change with temperature?
Above 70°C case temperature, the RMS on-state current must be derated linearly at a rate of 200 mA/°C until reaching 110°C.
What is the critical rate of rise of off-state voltage?
The critical rate of rise of off-state voltage (dv/dt) is typically ±20 V/µs at 110°C case temperature.
