Overview
The Littelfuse S8008DTP is a Silicon Controlled Rectifier (SCR) from the Sxx08x series, designed for surface-mount applications in a DPAK-2 (TO-252-2) package. It features an 8 A RMS on-state current and an 800 V rated repetitive off-state voltage. The device has a maximum holding current of 30 mA and a non-repetitive peak on-state current of 100 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 15 mA. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Surface-mount construction in a DPAK-2 package for automated assembly
- High thermal stability with a maximum operating temperature of +125°C
- Robust surge handling capability with 100 A non-repetitive peak current
Applications
- General purpose power control circuits
- AC switching applications
- Solid-state relay implementations
Procurement Notes
Verify the specific suffix 'TP' against the manufacturer's official datasheet to confirm packaging details, as standard designations may vary by distributor. Ensure the component meets RoHS compliance requirements for the target market. Cross-reference the Littelfuse part number directly with authorized distributors to confirm availability and authenticity before procurement.
Selection Notes
Select this SCR when an 800 V blocking voltage and 8 A continuous current are required in a compact surface-mount form factor. Compare the 1.5 V gate trigger voltage against the driving circuit capabilities to ensure reliable turn-on. Verify that the DPAK-2 thermal resistance is sufficient for the expected ambient conditions and heat dissipation requirements.
Part Context
This component belongs to the Littelfuse Sxx08x family of thyristors, which provides standardized performance for general-purpose power switching. The S8008DTP shares core electrical specifications with other variants in the series, differing primarily in packaging or minor manufacturing tolerances defined by the manufacturer.
Replacement Considerations
Compatible substitutes include the S8008DRP and S8008D56RP from Littelfuse, which share identical electrical ratings and pin configurations. Other manufacturers offering 8A/800V SCRs in TO-252 packages may serve as alternatives if pinout compatibility is verified.
