Overview
The Littelfuse S2025RTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx25x series, rated for 400V repetitive off-state voltage and 25A RMS on-state current. It features a TO-220AB flange mount package with three pins. Key electrical parameters include a forward voltage of 1.6V, gate trigger voltage of 1.5V, and gate trigger current of 35mA. The device supports an operating temperature range from -40°C to +125°C, with a maximum holding current of 50mA and non-repetitive peak on-state current of 350A.
Feature Summary
- High current handling capability with 25A RMS rating in a compact flange mount package
- Robust thermal performance supporting operation up to +125°C junction temperature
- Low gate trigger current requirement facilitating direct drive from logic circuits
Applications
- Industrial motor control systems requiring high current switching
- AC power regulation and phase control applications
- Solid-state relays and contactor replacement circuits
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number S2025RTP with official Littelfuse documentation. Ensure the ordering suffix matches the required package style and terminal configuration. Confirm RoHS compliance status through the specific datasheet revision before integration into production designs.
Selection Notes
Select this SCR when a 400V blocking voltage and 25A continuous current are required in a TO-220AB form factor. Compare gate trigger characteristics against driving circuit capabilities to ensure reliable turn-on. Evaluate thermal management requirements based on the 1.6V forward voltage drop at full load conditions.
Part Context
This component belongs to the Littelfuse Teccor Sxx25x family of silicon controlled rectifiers. These devices are designed for general purpose power switching applications. The S2025RTP specifically denotes the 400V variant within the 25A current rating lineup, sharing common packaging and basic electrical characteristics with other voltages in the series.
Replacement Considerations
Direct replacements must match the 25A RMS current, 400V VDRM, and TO-220AB package. Verify that substitute SCRs meet or exceed the 35mA gate trigger current and 1.6V forward voltage specifications to maintain circuit performance.
