1N4448W-AQ

Overview

The Diotec Semiconductor 1N4448W-AQ is a surface-mount small signal switching diode housed in an SOD-123F package. It features a maximum average forward current of 150 mA and a repetitive peak reverse voltage of 100 V. The device exhibits a very low junction capacitance of typically 2 pF at 0 V and 1 MHz, alongside a reverse recovery time of less than 4 ns. Forward voltage is specified as less than 0.855 V at 10 mA. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

AEC-Q101 qualified for automotive reliability standards
Extremely fast switching speed with low junction capacitance
Low leakage current characteristics
Compliant with RoHS, REACH, and Conflict Minerals regulations

Applications

High-speed switching circuits
Signal processing applications
Automotive electronics systems

Procurement Notes

Verify the specific AEC-Q101 qualification status against the latest official Diotec Semiconductor datasheet before integration. Confirm that the SOD-123F package dimensions and marking codes (D2) align with your PCB layout requirements. Ensure thermal management considerations account for the specified power dissipation limits under actual operating conditions.

Selection Notes

Select this component when high-speed switching performance and automotive-grade reliability are required in a compact surface-mount form factor. The low forward voltage drop and minimal junction capacitance make it suitable for precision signal handling. Verify compatibility with automated assembly processes due to the tape-and-reel packaging format.

Part Context

This part belongs to the 1N4148W/1N4448W series of SMD small signal switching diodes manufactured by Diotec Semiconductor. The -AQ suffix specifically denotes AEC-Q101 qualification, distinguishing it from standard commercial grade variants. It serves as a modern surface-mount replacement for through-hole switching diodes in space-constrained designs.
