Overview
The Littelfuse S8008V is a Silicon Controlled Rectifier (SCR) designed for high-power switching applications. It features an 8 A maximum on-state current and an 800 V repetitive peak off-state voltage rating. The device is housed in a TO-251AA (DPAK) surface-mount package with three terminals. Key electrical characteristics include a maximum DC gate trigger current of 15 mA, a maximum DC gate trigger voltage of 1.5 V, and a holding current of 30 mA. It exhibits a critical rate of rise of off-state voltage of 200 V/us and supports a non-repetitive peak on-state current of 100 A. The component is lead-free, RoHS compliant, and UL recognized.
Feature Summary
- High-voltage blocking capability suitable for demanding power control circuits
- Surface-mount DPAK packaging facilitates automated assembly and compact board layouts
- Robust surge handling with high non-repetitive peak current capacity
Applications
- Industrial motor control systems
- Solid-state relays
- Power supply regulation circuits
Procurement Notes
Verify the specific ordering suffix to confirm the exact package variant and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your manufacturing process. Ensure the thermal management design accommodates the TO-251AA package's dissipation capabilities under continuous load conditions.
Selection Notes
Select this component when an 800 V blocking voltage and 8 A continuous current are required in a surface-mount form factor. Evaluate the gate trigger parameters against your driving circuit's output capabilities. Consider the thermal resistance of the TO-251AA package for your specific ambient temperature and heat sinking constraints.
Part Context
The S8008V belongs to Littelfuse's standard SCR portfolio, which provides reliable phase-control solutions for industrial and commercial power applications. This series is engineered for durability in environments requiring robust overcurrent protection and precise switching timing.
Replacement Considerations
Cross-reference with other 8A/800V SCRs in the TO-251AA package from Littelfuse or compatible manufacturers. Verify pinout compatibility and ensure equivalent gate trigger characteristics before substitution.
