Overview
The Littelfuse SK008NTP is a silicon-controlled rectifier (SCR) rated for 1 kV blocking voltage and 8 A RMS on-state current. It features a standard recovery type with a maximum on-state voltage of 1.6 V at 5.1 A average current. The device operates within a junction temperature range of -40°C to 125°C. Key electrical limits include a maximum gate trigger voltage of 1.5 V, a maximum gate trigger current of 15 mA, and a holding current of 30 mA. Non-repetitive peak surge currents are specified as 83 A at 50/60 Hz and 100 A under other conditions. The component is housed in a TO-263 (D2PAK) surface-mount package.
Feature Summary
- Surface-mount construction in a D2PAK package for automated assembly
- Standard recovery characteristics suitable for general switching applications
- High thermal stability with an operating junction temperature up to 125°C
Applications
- General purpose AC/DC power control circuits
- Industrial motor speed control systems
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix NTP against the official Littelfuse datasheet Sxx08xSx to confirm the TO-263 package variant. Ensure that the ordering information matches the required lead time and packaging quantity, which may differ from other series members like SK008DRP or SK008VTP. Cross-reference part numbers carefully to avoid substitution errors between different package types within the same electrical family.
Selection Notes
Select this component when a 1 kV SCR with 8 A RMS capability is required in a surface-mount form factor. Compare the 1.6 V on-state voltage drop against system efficiency requirements. Verify that the 15 mA gate trigger current aligns with the driving circuit's output capabilities. Consider the thermal resistance of the D2PAK package for heat dissipation planning in the final enclosure design.
Part Context
This device belongs to the Littelfuse Sxx08xSx series, which groups SCRs with similar 8 A electrical ratings but varying package options. Other variants in this family include the through-hole SK008VTP in a TO-251 package and the surface-mount SK008DRP in a TO-252AA package. All share identical core electrical specifications, allowing for design flexibility based on manufacturing constraints.
Replacement Considerations
The SK008NRP is listed as a parameter-equivalent alternative within the same manufacturer portfolio. Both devices share the 1 kV, 8 A rating but utilize different package styles. Verify mechanical footprint compatibility before substituting. No third-party cross-references are confirmed in the provided documentation.
