Overview
The Littelfuse S6025NRP is a Silicon Controlled Rectifier (SCR) from the Teccor Sxx25x series, designed for surface mount applications in the SMTO-263-2 package. It features a rated repetitive off-state voltage of 400 V and an on-state RMS current of 25 A. The device exhibits a maximum holding current of 50 mA and a non-repetitive peak on-state current of 350 A. Electrical characteristics include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 35 mA. It operates within a temperature range of -40°C to +125°C and maintains an off-state leakage current of 10 µA at VDRM.
Feature Summary
- Surface mount construction in a compact SMTO-263-2 package for automated assembly
- High surge current capability with a 350 A non-repetitive peak rating
- Robust thermal performance supporting operation up to 125°C junction temperature
Applications
- Industrial motor control circuits requiring high current switching
- Solid state relay designs utilizing surface mount technology
- General purpose power control systems operating at 400 V
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure the procurement channel provides official Littelfuse documentation to validate RoHS compliance and UL recognition status before integration into production.
Selection Notes
Select this component when a 400 V SCR is required in a surface mount form factor. Compare the 25 A RMS current rating against circuit load requirements. Verify that the 35 mA gate drive capability matches the control interface voltage levels and that the SMTO-263-2 footprint fits the PCB layout constraints.
Part Context
This part belongs to the Littelfuse Teccor Sxx25x family of thyristors. It shares the 25 A current handling characteristic with other members like the S6025R57 but differs in voltage rating and package style. The S6025NRP specifically targets lower voltage applications compared to the 600 V variants in the same series.
Replacement Considerations
Direct substitutes must match the 400 V rating, 25 A current, and SMTO-263-2 package. Cross-reference with other Sxx25x series parts such as S4025NRP for identical electrical parameters. Verify pinout compatibility and thermal resistance values before substitution.
