S6025RTP

Overview

The Littelfuse S6025RTP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx25x series, designed for high-current switching applications. It features a rated repetitive off-state voltage (VDRM) of 400 V and an on-state RMS current (It RMS) of 25 A. The device exhibits a maximum forward voltage drop (Vf) of 1.6 V at conduction. Gate triggering requirements include a maximum gate trigger voltage (Vgt) of 1.5 V and a maximum gate trigger current (Igt) of 35 mA. The component operates within a junction temperature range of -40°C to +125°C and is housed in a TO-220-2 through-hole package.

Feature Summary

• High current handling capability with 25 A RMS rating for robust power control
• Low on-state voltage drop of 1.6 V to minimize conduction losses
• Sensitive gate trigger characteristics allowing direct drive from logic circuits
• Robust thermal performance suitable for demanding industrial environments

Applications

• Industrial motor speed control systems
• Solid-state relay modules
• AC power regulation circuits
• Welding equipment power stages

Procurement Notes

Verify the specific suffix 'RTP' against the manufacturer's official datasheet to confirm packaging type and compliance status. Ensure the procurement channel provides valid traceability documentation. Cross-reference the part number with Littelfuse's current production status to avoid obsolete stock. Confirm that the delivered components match the specified TO-220-2 package dimensions.

Selection Notes

Select this component when a 400 V blocking voltage and 25 A continuous current are required in a standard through-hole configuration. Compare the 1.5 V gate trigger threshold against available drive circuit capabilities to ensure reliable turn-on. Evaluate the thermal resistance of the TO-220-2 package against the expected heat dissipation requirements of the target application.

Part Context

This SCR belongs to the Teccor Sxx25x family, which groups thyristors by their 25 A current rating. The S6025RTP specifically denotes the 400 V variant within this series. This family is engineered for general-purpose AC power control, offering a balance between high current capacity and manageable gate drive requirements for industrial designers.

Replacement Considerations

Direct replacements must maintain the 25 A RMS current and 400 V voltage ratings. Verify pinout compatibility for the TO-220-2 package. Check if alternative parts offer identical or lower gate trigger currents to ensure interface compatibility without redesigning the drive circuitry.
