1N4148WH RHG

Single Diodes Overview

The Taiwan Semiconductor Corporation 1N4148WH RHG is a small-signal switching diode designed for high-speed applications. It features a silicon epitaxial planar construction housed in an SOD-323 surface-mount package. The device provides a peak repetitive reverse voltage of 75 V and supports a maximum average forward rectified current of 150 mA. Key electrical characteristics include a fast reverse recovery time of 4 ns and a low junction capacitance, ensuring efficient signal processing. The component operates within a temperature range from -65 °C to +200 °C, offering robust thermal performance for demanding electronic circuits.

Single Diodes Feature Summary

• High-speed switching capability with minimal reverse recovery delay
• Low junction capacitance for improved signal integrity
• Extended operating temperature range up to 200 °C

Single Diodes Applications

• High-frequency signal switching circuits
• Digital logic interface protection
• Clamping and clamping diodes in RF applications

Single Diodes Procurement Notes

Verify the specific suffix RHG against official datasheets to confirm lead-free status and tape-and-reel packaging specifications. Ensure compatibility with automated pick-and-place equipment by checking reel dimensions. Confirm RoHS compliance documentation matches current regulatory requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when space constraints require an SOD-323 footprint instead of traditional axial packages. It serves as a direct replacement for standard 1N4148 variants where higher thermal stability or surface-mount assembly is required. Evaluate reverse leakage current specifications if used in high-impedance analog front ends.

Single Diodes Part Context

This part belongs to the widely adopted 1N4148 family of small-signal switching diodes. While traditional versions utilize DO-35 glass encapsulation, this variant adapts the functionality for modern surface-mount technology. It maintains the core electrical profile of its through-hole predecessors while enabling denser PCB layouts and automated manufacturing processes.

Single Diodes Replacement Considerations

Direct substitutes include other SOD-323 packaged 1N4148 variants from manufacturers such as Vishay (1N4148WS) or onsemi (1N4148WT). Verify pinout orientation and marking codes to ensure correct cathode/anode alignment during assembly.
