1N4448W-AQ is listed in the Single Diodes range at ChipApex. The manufacturer field lists Diotec Semiconductor. Its product description is DIODE STANDARD 75V 150MA SOD123F. Review the specifications below when checking this part for your BOM.
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.
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.
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.
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.
The 1N4148W-AQ is electrically similar but may differ in package outline compared to the 1N4448W-AQ.
