Overview
The Littelfuse S8008VTP is a Silicon Controlled Rectifier (SCR) from the 808 Series, designed for high-voltage switching applications. It features an 8 A RMS on-state current and a 1 kV repetitive peak off-state voltage rating. The device utilizes a standard recovery gate structure and is housed in a TO-251 (V-Pak/I-Pak) surface-mount package with short leads. Key electrical parameters include a maximum DC gate trigger current of 15 mA, a holding current of 30 mA, and a non-repetitive surge current capability of 100 A at 60 Hz. It operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- High voltage blocking capability suitable for demanding power control circuits
- Surface-mount TO-251 package design for automated assembly and compact layouts
- Standard recovery characteristics optimized for general-purpose AC/DC switching
Applications
- Industrial motor control systems requiring high-voltage isolation
- Solid-state relays and contactors for heavy-duty switching
- Power supply overvoltage protection circuits
Procurement Notes
Verify the specific suffix 'VTP' against the manufacturer's official datasheet to confirm pinout orientation and lead configuration. Ensure that the required thermal management solutions align with the TO-251 package's thermal resistance specifications. Confirm RoHS compliance status for the specific production batch if environmental regulations apply to the final assembly.
Selection Notes
Select this component when a surface-mount SCR with 1 kV blocking voltage and 8 A continuous current is required. Compare the 15 mA gate trigger current against available drive circuit capabilities. Evaluate the TO-251 package size constraints against PCB layout requirements. Consider the standard recovery time if high-frequency switching operations are involved in the target application design.
Part Context
The S8008VTP belongs to Littelfuse's 808 Series of silicon controlled rectifiers. This series is engineered for robust performance in industrial and commercial power electronics. The VTP suffix typically denotes a specific tape-and-reel packaging format intended for automated surface-mount placement processes, distinguishing it from bulk or axial-leaded variants.
Replacement Considerations
The SK008VTP is documented as a parameter-equivalent alternative. Verify that the substitute maintains identical voltage ratings, current handling, and package dimensions before integration into existing designs.
