1N4448W-G3-18

Overview

The Vishay 1N4448W-G3-18 is a small signal fast switching diode housed in an SOD-123 surface-mount package. It features a maximum reverse voltage of 75 V and a continuous forward current rating of 300 mA. The device exhibits a typical reverse recovery time of 4 ns and a low junction-to-ambient thermal resistance of 440 K/W. Electrical characteristics include a forward voltage of 0.72 V at 5 mA and a leakage current of 2 µA at 75 V. The component operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon epitaxial planar construction for high-speed switching applications
• Molding compound meets UL 94 V-0 flammability rating
• Moisture sensitivity level 1 (MSL 1) per J-STD-020 standards

Applications

• High-speed switching circuits
• General-purpose rectification
• Clamping and protection applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging options and minimum order quantities. Ensure that the selected variant matches the required tape and reel specifications for automated assembly processes. Cross-reference the document number 86363 with the latest revision to confirm compliance with current RoHS directives and material categorization requirements.

Selection Notes

Select this component when a compact SOD-123 footprint is required for high-frequency signal processing. The 4 ns reverse recovery time makes it suitable for applications demanding rapid transition speeds. Consider the 75 V reverse voltage rating and 300 mA forward current capability to ensure adequate headroom for the target circuit design under varying thermal conditions.

Part Context

This part belongs to the Vishay 1N4448W series of small signal fast switching diodes. The 'G3' designation indicates a green, commercial-grade product compliant with RoHS directives. The '-18' suffix specifies the standard 10,000 units per reel packaging configuration on a 13-inch reel using 8 mm tape.

Replacement Considerations

Direct substitutes within the same Vishay family include the 1N4448W-G3-08, which shares identical electrical characteristics but utilizes 3,000 units per reel packaging.
