1N4448WX-TP

Overview

The 1N4448WX-TP is a high-voltage, fast-switching diode manufactured by Micro Commercial Components (MCC). It features a peak repetitive reverse voltage of 100 V and an average forward current rating of 250 mA. The device exhibits a maximum reverse recovery time of 4 ns and a junction capacitance of 4 pF at 0 V. Electrical characteristics include a forward voltage of up to 1.25 V at 150 mA and a maximum reverse leakage current of 1 µA at 75 V. It operates within a junction temperature range of -65°C to +150°C and is housed in the SOD-323 surface-mount package.

Feature Summary

• Fast switching speed with a maximum reverse recovery time of 4 ns
• High conductance capability for efficient signal handling
• Halogen-free construction meeting UL 94 V-0 flammability ratings

Applications

• General-purpose high-speed switching circuits
• Clamping and protection applications requiring fast response
• Low-power rectification in compact electronic designs

Procurement Notes

Verify authenticity by purchasing only from MCC or authorized distributors to ensure traceability and quality standards. Confirm the specific ordering suffix matches the required packing type, such as T5 for 7-inch tape and reel quantities. Check the latest datasheet revision for any updates to mechanical dimensions or electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component for applications demanding high-voltage isolation combined with rapid switching performance. The SOD-323 package offers a compact footprint suitable for space-constrained PCB layouts. Ensure thermal management accounts for the specified power dissipation limits when operating near maximum ambient temperatures.

Part Context

This part belongs to the 1N4448WX series of small-signal switching diodes produced by Micro Commercial Components. It serves as a modern surface-mount alternative to traditional through-hole switching diodes, providing comparable electrical performance in a significantly smaller form factor designed for automated assembly processes.

Replacement Considerations

Direct substitutes include other 1N4448 variants from different manufacturers that match the SOD-323 package and 100V/250mA ratings. Verify pinout orientation and reverse recovery times to ensure functional equivalence in high-speed circuit designs.
