1N4448X-TP

Overview

The 1N4448X-TP is a small signal switching diode manufactured by Micro Commercial Components (MCC). It features a single configuration in an SOD-523 surface-mount package. Key electrical parameters include a peak reverse voltage of 75 V, a maximum forward current of 500 mA, and a surge current rating of 4 A. The device exhibits a fast recovery time of 4 ns with a forward voltage of 1.25 V at specified conditions and a reverse leakage current of 2.5 uA. It operates within a junction temperature range of -65 C to +150 C.

Feature Summary

• Fast switching capability with 4 ns recovery time for high-speed digital applications
• Compact SMD/SMT form factor suitable for automated insertion and space-constrained designs
• High thermal stability supporting operation up to +150 C junction temperature

Applications

• General purpose signal switching circuits
• High-speed digital logic interfaces
• Clamping and protection in low-voltage signal paths

Procurement Notes

Verify the specific suffix and packaging type against the official MCC datasheet to ensure compatibility with assembly requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability. Ensure the selected reel or cut tape quantity matches production needs without relying on speculative availability data.

Selection Notes

Select this component when a standard silicon switching diode with 75 V reverse voltage rating is required in a compact SOD-523 footprint. Consider the 500 mA average forward current and 4 ns recovery speed for general-purpose high-frequency applications. Evaluate the -65 C to +150 C operating range against environmental constraints. Compare against alternative packages like SOD-123 if higher power dissipation or different mechanical constraints are necessary.

Part Context

The 1N4448X-TP belongs to the 1N4448X series of small signal switching diodes from Micro Commercial Components. It serves as a surface-mount equivalent to traditional through-hole switching diodes, offering similar electrical characteristics in a smaller package. The product falls under the Diodes & Rectifiers category, specifically designed for general-purpose switching tasks in consumer electronics and industrial control systems.
