Overview
The S8025NTP is a Silicon-Controlled Rectifier (SCR) manufactured by Littelfuse under the Teccor brand. It features an 800 V rated repetitive off-state voltage and supports a 25 A RMS on-state current. The device utilizes a surface-mount TO-263AB-3 package for efficient thermal management. Key electrical characteristics include a maximum gate trigger current of 35 mA, a holding current of 50 mA, and a forward voltage drop of 1.6 V at rated current. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Sensitive gate structure allows direct interfacing with microprocessors using minimal trigger current.
- Glass passivated junctions provide enhanced durability against environmental stressors.
- Surface mount construction enables compatibility with automated pick-and-place assembly processes.
Applications
- Capacitive-discharge ignition systems
- Fluid level sensors
- Strobe light control circuits
Procurement Notes
Verify the specific suffix 'NTP' against official Littelfuse documentation to confirm exact packaging configuration and lead-free status. Ensure the selected variant matches the required tape and reel specifications for your manufacturing line. Cross-reference the datasheet revision date to guarantee parameter accuracy during procurement.
Selection Notes
Select this component when an 800 V blocking capability and 25 A continuous current handling are required in a compact surface-mount form factor. Evaluate the 35 mA gate trigger requirement against your driving circuit's output capabilities. Confirm that the TO-263AB-3 thermal resistance meets your system's heat dissipation constraints under peak load conditions.
Part Context
This SCR belongs to the Sxx25x series, designed for general-purpose switching applications. It complements other devices like the S8025NRP, differing primarily in packaging or minor electrical tolerances. The series emphasizes robust performance in industrial controls and consumer electronics requiring reliable thyristor switching.
Replacement Considerations
Direct substitutes may include the S8025NRP if pinout and electrical ratings align perfectly. Verify that any alternative maintains the same TO-263AB-3 footprint and 800 V / 25 A specifications to ensure mechanical and functional compatibility without redesigning the PCB layout.
