Overview
The Littelfuse SK008RTP is a silicon-controlled rectifier (SCR) from the SK series, rated for 1 kV repetitive peak off-state voltage and 8 A RMS on-state current. It features a gate trigger voltage of 1.5 V and a gate trigger current of 15 mA, with a forward voltage drop of 1.6 V at conduction. The device supports a maximum non-repetitive surge current of 100 A and has a holding current of up to 30 mA. Designed for surface-mount applications, it utilizes a DPAK-2 (TO-252-2) package and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Surface-mount construction in a compact DPAK-2 package for automated assembly
- High thermal performance capability supporting operation up to +125°C
- Sensitive gate control optimized for digital circuitry integration
Applications
- AC solid-state switching circuits
- Phase control applications such as motor speed regulation
- Temperature modulation controls
Procurement Notes
Verify the specific suffix 'RTP' against official Littelfuse documentation to confirm surface-mount packaging and tube packing details. Ensure compatibility with DPAK-2 footprint requirements during design-in. Confirm RoHS compliance status through the manufacturer's latest datasheet before procurement.
Selection Notes
Select this component when a high-voltage SCR is required in a surface-mount form factor. The 8 A rating suits moderate power loads, while the 1 kV blocking voltage provides robust protection against line transients. Verify that the gate drive circuit can supply the specified 15 mA trigger current reliably across the operating temperature range.
Part Context
The SK008RTP belongs to the Littelfuse SK series of thyristors, which are designed for general-purpose AC switching and phase control. This series offers a balance of high voltage blocking capabilities and current handling in various packages, including through-hole and surface-mount options, catering to diverse industrial and consumer electronics needs.
Replacement Considerations
The SK008DTP is a verified equivalent part number within the same series, sharing identical electrical ratings and utilizing the same DPAK-2 package. Cross-reference pinouts and thermal characteristics to ensure direct interchangeability in existing designs.
