1N4148W-AQ

Single Diodes Overview

The Diotec Semiconductor 1N4148W-AQ is a surface-mount small signal switching diode housed in an SOD-123F package. It features a maximum repetitive peak reverse voltage (VRRM) of 100 V and a maximum average forward current (IFAV) of 150 mA. The device exhibits a very high switching speed with a reverse recovery time (trr) of less than 4 ns, alongside low junction capacitance typically at 2 pF. Forward voltage characteristics include a maximum of 0.715 V at 1 mA and 0.855 V at 10 mA. The component operates within a junction temperature range of -55°C to +150°C and carries the marking code W1.

Single Diodes Procurement Notes

Verify that the specific part number includes the -AQ suffix to confirm AEC-Q101 qualification status. Ensure the ordering quantity matches the standard tape and reel packaging configuration. Confirm compliance requirements such as RoHS and REACH status directly with the manufacturer documentation prior to final procurement decisions.

Single Diodes Selection Notes

Select this component when a compact SMD solution is required for high-speed digital or analog switching. The SOD-123F package offers a low-profile footprint ideal for space-constrained designs. Consider the 150 mA current rating and 100 V reverse voltage limits to ensure adequate headroom for the target circuit application.

Single Diodes Part Context

This device belongs to the 1N4148 family of small signal switching diodes manufactured by Diotec Semiconductor. It serves as the surface-mount equivalent to traditional through-hole variants, providing identical electrical performance in a modern SMD form factor. The -AQ designation specifically denotes automotive-grade qualification within this product line.

Single Diodes Replacement Considerations

Consult official Diotec documentation for verified cross-reference part numbers. Alternative packages such as DO-35 or MiniMELF may offer functional equivalence but require mechanical verification.
