S4008DRP

Overview

The Littelfuse S4008DRP is a high-speed silicon rectifier diode designed for general-purpose applications. It features an axial-leaded DO-15 package, providing robust mechanical stability and thermal dissipation capabilities. The device is engineered to handle repetitive peak forward current of 4.0 Amperes with a non-repetitive surge current rating of up to 130 Amperes. Key electrical specifications include a maximum average forward rectified current of 4.0 A at a case temperature of 75°C and a maximum DC blocking voltage (VRRM) of 1000 Volts. The component exhibits a low forward voltage drop and fast recovery characteristics, making it suitable for efficient power conversion circuits.

Feature Summary

• High-speed recovery characteristics for efficient switching performance
• Robust axial-leaded construction for reliable mounting
• High surge current capability for transient protection

Applications

• General-purpose rectification in AC/DC converters
• Freewheeling diodes in inductive load circuits
• Power supply input stages

Procurement Notes

Verify the specific suffix 'DRP' against manufacturer documentation to confirm packaging details such as tape-and-reel configuration or specific marking codes. Ensure that the ordering information matches the exact voltage and current ratings required for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 4A continuous current rating and 1000V reverse voltage are required in an axial package. Consider the forward voltage drop and reverse leakage current specifications relative to thermal management constraints. Verify compatibility with operating frequency requirements due to its high-speed classification compared to standard rectifiers.

Part Context

This part belongs to Littelfuse's series of high-speed silicon rectifiers. These components are typically utilized in industrial and consumer electronics where compact size and high reliability are paramount. The DO-15 package offers a balance between current handling capacity and physical footprint, distinguishing it from smaller signal diodes and larger bridge rectifiers.

Replacement Considerations

Potential substitutes must match the 4A current rating, 1000V reverse voltage, and axial DO-15 form factor. Verify equivalent forward voltage drop and reverse recovery time to ensure circuit performance parity. Consult official cross-reference lists for confirmed compatible parts from other manufacturers.
