Overview
The Littelfuse S8025NRP is a surface-mount Silicon-Controlled Rectifier (SCR) from the Teccor Sxx25x series, housed in an SMTO-263-2 package. It features a rated repetitive off-state voltage of 800 V and an RMS on-state current of 25 A. The device has a maximum forward voltage of 1.6 V, with gate trigger parameters of 1.5 V and 35 mA. It operates within a temperature range of -40°C to +125°C and includes a non-repetitive peak surge current capability of 350 A.
Feature Summary
- Sensitive gate design allows for direct interfacing with microprocessors using minimal gate current.
- Glass passivated junctions ensure durability against environmental stressors.
- Compatible with lead-free reflow soldering processes for modern manufacturing requirements.
Applications
- Capacitive-discharge ignition systems
- Fluid level sensors
- Strobe light control circuits
Procurement Notes
Verify the specific ordering suffix to confirm the exact packaging configuration, such as cut tape or reel, as these affect handling procedures. Confirm RoHS compliance status through the manufacturer's official documentation before integration into regulated assemblies. Ensure the selected variant matches the required thermal management specifications for the target application environment.
Selection Notes
Select this component when an 800 V blocking voltage and 25 A continuous current rating are required in a surface-mount form factor. Consider the 1.6 V on-state voltage drop for power dissipation calculations. Verify that the 35 mA gate trigger current aligns with the driving circuit's output capabilities. Ensure the SMTO-263-2 footprint fits the PCB layout constraints.
Part Context
This SCR belongs to the Littelfuse Teccor Sxx25x family, which standardizes 25 A ratings across various voltage classes. The 'S' prefix typically denotes standard recovery characteristics, while the '80' indicates the 800 V voltage rating. The 'NRP' suffix specifies the surface-mount package and packaging type, distinguishing it from through-hole equivalents like the S8025RTP.
Replacement Considerations
Direct pin-compatible replacements within the same voltage class include other SMD SCRs from the Sxx25x series with identical or higher voltage ratings. Cross-reference datasheets for gate trigger currents and holding currents to ensure circuit stability. Verify thermal resistance values if replacing with components from different manufacturers.
