1N4448W RHG

Overview

The Taiwan Semiconductor Corporation 1N4448W RHG is a standard silicon signal diode housed in an SOD-123F surface-mount package. It features a maximum DC reverse voltage of 75 V and an average forward rectified current of 150 mA. The device exhibits a fast reverse recovery time of 4 ns, with a maximum forward voltage drop of 1 V at 100 mA and a reverse leakage current of 5 µA at 75 V. Operating junction temperatures range from -65°C to 150°C.

Feature Summary

• Fast switching capability with 4 ns reverse recovery time
• High thermal stability across wide temperature ranges
• Compact surface-mount design for automated assembly

Applications

• High-speed digital logic circuits
• Clamping and protection applications
• Signal demodulation and detection

Procurement Notes

Verify the specific suffix RHG against manufacturer documentation to confirm exact binning or tape-and-reel specifications. Ensure compatibility with SOD-123F footprint requirements during procurement planning. Cross-reference datasheets for any recent product change notifications that may affect pinout or material composition.

Selection Notes

Select this component when a compact SMD solution is required for 75V blocking applications. Compare against DO-35 variants if higher surge current ratings are necessary. Evaluate thermal management needs given the small package size and high operating temperature limit.

Part Context

This part belongs to the 1N4448 family of general-purpose switching diodes. It serves as a surface-mount alternative to through-hole packages like DO-35. The W suffix typically indicates a specific reel quantity or packaging format defined by the manufacturer.

Replacement Considerations

Direct substitutes include Vishay 1N4448WS-E3-08 and MCC 1N4448W-TP. Verify package dimensions and electrical parameters match before substitution.
