1N4448WS

Single Diodes Overview

The 1N4448WS is a small-signal switching diode manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It features a peak reverse voltage of 100 V and an average forward current rating of 150 mA. The device exhibits a fast recovery time of 4 ns and a maximum forward voltage of 1 V at 100 mA. Reverse leakage current is specified at 25 nA. It operates within a junction temperature range of -65°C to +175°C and is housed in the SOD-323F surface-mount package.

Single Diodes Feature Summary

• High conductance design for efficient signal switching
• Fast switching speed with minimal recovery delay
• Compact surface-mount footprint for automated assembly

Single Diodes Applications

• General purpose high-speed switching circuits
• Clamping and protection applications
• Signal demodulation in communication equipment

Single Diodes Procurement Notes

Verify the manufacturer designation as Shenzhen Slkormicro Semicon Co., Ltd. against official datasheets. Confirm the SOD-323F package dimensions and electrical parameters match project requirements. Ensure compliance with RoHS directives if applicable. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Single Diodes Selection Notes

Select this component for designs requiring fast recovery characteristics in a compact SMD form factor. Compare the 100 V reverse voltage and 150 mA forward current limits against circuit demands. Evaluate thermal management needs given the 175°C maximum junction temperature. Consider the low leakage current for sensitive analog or RF signal paths.

Single Diodes Part Context

This component belongs to the standard small-signal switching diode category, often used as a replacement for legacy through-hole devices like the 1N4448 in modern PCB layouts. The SOD-323F package allows for higher density mounting compared to axial leads. It serves as a fundamental discrete semiconductor element for logic level shifting and signal routing.

Single Diodes Replacement Considerations

Direct substitutes include the 1N4448W from other manufacturers offering identical SOD-123/SOD-323F footprints and electrical specifications. Verify pinout compatibility and thermal resistance values when swapping between different brand offerings.
