Overview
The Littelfuse S8025RTP is a silicon-controlled rectifier (SCR) rated for 1000V repetitive peak off-state voltage and 25A RMS on-state current. It utilizes a TO-220AB flange mount package with three terminals. Key electrical parameters include a maximum gate trigger voltage of 1.5V, a maximum gate trigger current of 35mA, and a holding current of 50mA. The device supports a non-repetitive peak on-state current of 350A and has a critical rate of rise of off-state voltage of 300 V/us. Operating temperatures range from -40°C to +125°C.
Feature Summary
- High voltage blocking capability suitable for demanding power switching applications
- Sensitive gate structure allowing direct interfacing with low-power control circuits
- Robust thermal management design via flange mount packaging
Applications
- Industrial motor controls
- Power supply regulation
- Solid-state relays
Procurement Notes
Verify the specific suffix RTP against the manufacturer's official datasheet to confirm pinout and mounting configuration. Ensure the procurement documentation explicitly states the 1000V rating, as similar models in the series may have lower voltage ratings. Confirm RoHS compliance status through the latest component certification documents provided by Littelfuse.
Selection Notes
Select this component when high voltage isolation is required alongside moderate current handling. The TO-220AB package facilitates heatsinking for thermal dissipation. Compare the 300 V/us dv/dt rating against circuit transient conditions to ensure reliable turn-off. Verify that the 35mA gate drive capability matches the output specifications of the triggering microcontroller or logic circuit.
Part Context
This device belongs to the Littelfuse Teccor Sxx25x series of standard recovery SCRs. The series offers various voltage ratings while maintaining consistent current and thermal characteristics. The S8025RTP specifically addresses high-voltage requirements within this family, providing a standardized solution for industrial thyristor applications requiring robust performance.
Replacement Considerations
Cross-reference part numbers such as S8025NRP for surface-mount alternatives if PCB space is constrained. Verify that substitute components maintain identical voltage, current, and thermal specifications. Check for package compatibility changes between through-hole and surface-mount variants.
