1N4448

Single Diodes Overview

The Diotec Semiconductor 1N4448 is a small signal switching diode designed for commercial and industrial applications. It features a repetitive peak reverse voltage of 100 V and a maximum average forward current of 200 mA. The device exhibits a very high switching speed with a reverse recovery time of less than 4 ns and low junction capacitance of approximately 4 pF. It operates within a junction temperature range of -50°C to +175°C and supports non-repetitive peak forward currents up to 4000 mA.

Single Diodes Feature Summary

• Extremely fast switching capability suitable for high-speed signal processing
• Low junction capacitance and low leakage current characteristics
• Compliant with RoHS, REACH, and Conflict Minerals regulations

Single Diodes Applications

• Signal processing circuits
• High-speed switching applications

Single Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. Suffixes such as -Q indicate AEC-Q101 compliance, while -AQ denotes AEC-Q101 qualification. Confirm package availability, as the component is offered in DO-35 and SOD-27 configurations. Ensure the selected variant matches the required reliability grade for the intended commercial or industrial environment.

Single Diodes Selection Notes

Select this component for designs requiring rapid signal transition and minimal parasitic effects. The 100 V reverse voltage rating provides adequate headroom for standard logic levels. Consider the thermal resistance and power dissipation limits when determining heat management requirements for dense circuit layouts.

Single Diodes Part Context

This part belongs to the Diotec 1N4148 family of small signal switching diodes. It shares similar electrical specifications with the 1N4148, 1N4150, and 1N4151 variants. The primary distinction lies in the specific voltage and current ratings defined for each model within the series.

Single Diodes Replacement Considerations

Direct substitutes include the 1N4148, 1N4150, and 1N4151 from Diotec Semiconductor. Verify that alternative manufacturers' equivalents meet the 4 ns reverse recovery time and 100 V reverse voltage requirements.
