Overview
The Littelfuse SK008DTP is a silicon-controlled rectifier (SCR) rated for 1 kV repetitive peak off-state voltage and 8 A RMS on-state current. It utilizes a DPAK-2 (TO-252-2) surface-mount package designed for high-power density applications. Key electrical parameters include a maximum forward voltage of 1.6 V, gate trigger voltage of 1.5 V, and gate trigger current of 15 mA. The device supports an operating junction temperature range from -40°C to +125°C with a non-repetitive peak surge current capability of 100 A.
Feature Summary
- Glass-passivated junctions provide robust protection against mechanical stress and chemical corrosion.
- Surface-mount construction in a DPAK-2 package facilitates automated assembly and compact PCB layouts.
- High thermal performance enables reliable operation in demanding power control environments.
Applications
- AC/DC motor speed controls
- Lighting dimmers
- Solid-state relays
Procurement Notes
Verify the specific suffix 'DTP' corresponds to the DPAK-2 surface-mount package configuration. Confirm RoHS compliance status through official Littelfuse documentation prior to integration. Ensure ordering quantities align with manufacturer tube packaging standards to avoid supply discrepancies.
Selection Notes
Select this component when a 1 kV blocking voltage and 8 A continuous current are required in a surface-mount form factor. Evaluate thermal management requirements based on the 1.6 V forward voltage drop at full load. Compare against TO-220 variants if higher thermal dissipation or through-hole mounting is necessary for the specific chassis design.
Part Context
This part belongs to the SK series of standard recovery SCRs manufactured by Littelfuse. The series offers various voltage ratings and package options to suit different industrial and consumer power control needs. The DTP suffix specifically identifies the surface-mount variant within this product family.
Replacement Considerations
Consult Littelfuse datasheets for direct pin-compatible alternatives within the SK series. Verify that any substitute maintains identical voltage, current, and thermal specifications to ensure circuit integrity without redesign.
