1N4148

Single Diodes Overview

The Diotec Semiconductor 1N4148 is a small signal switching diode housed in the DO-35 axial leaded package. It features a maximum repetitive peak reverse voltage of 100 V and a continuous average forward current rating of 200 mA. The device exhibits a very fast reverse recovery time of less than 4 ns, making it suitable for high-speed applications. Key electrical parameters include a maximum forward voltage of 1.0 V at 10 mA, a typical junction capacitance of 4 pF at 0 V, and a maximum leakage current of 5 µA at 75 V. The component supports a maximum junction temperature of 175°C.

Single Diodes Feature Summary

• Extremely fast switching speed with low reverse recovery time
• Low junction capacitance for minimal signal distortion
• Low leakage current to ensure efficient operation
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Diodes Applications

• Signal processing circuits

Single Diodes Procurement Notes

Verify that the specific part number matches the required commercial or industrial grade specifications. Confirm compliance requirements such as AEC-Q101 if automotive standards are necessary by checking for appropriate suffixes like -Q or -AQ. Ensure the ordering documentation aligns with the manufacturer's standard terms and conditions regarding product changes and liability limitations.

Single Diodes Selection Notes

Select this component when a general-purpose silicon switching diode with an axial leaded package is required. The 1N4148 offers a balance of high voltage tolerance and rapid switching capabilities. Consider the thermal resistance and power dissipation limits relative to the ambient operating conditions and lead mounting distance specified in the datasheet.

Single Diodes Part Context

This component belongs to the 1N4148 family of small signal switching diodes manufactured by Diotec Semiconductor. It shares characteristics with related models such as the 1N4150, 1N4151, and 1N4448, which vary primarily in their reverse voltage ratings. The standard version is designed for commercial and industrial applications requiring ordinary reliability levels.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4148 equivalents. Verify pinout compatibility and package dimensions (DO-35) for direct replacement. Check if specific performance margins like leakage current or recovery time meet the original design constraints.
