Signal Diodes for SMD Assembly

This pack contains one hundred 1N4148 switching diodes in SOD-123 surface-mount packages. They are intended for builders assembling their own printed circuit boards. The components suit hobbyists and engineers working on compact electronic designs.

SOD-123 Surface-Mount Package

Each diode uses the SOD-123 footprint designed for automated or hand soldering onto SMD pads. Through-hole prototyping is not supported without adapter boards. Buyers uncomfortable with fine-pitch soldering should consider alternative component styles.

Low-Power Signal Rectification

These devices handle small-signal switching tasks only and are not rated for power rectification. Forward voltage drop and leakage current remain minimal during typical logic-level operation. Thermal load is negligible in standard keyboard matrix or signal-routing applications.

Questions about this item

How many 1N4148 SOD-123 diodes are included in the pack?

The pack contains 100 individual diodes, each in an SOD-123 surface-mount package, ready for placement on a compatible PCB.

What circuit tasks are these 1N4148 diodes rated for?

They are designed for small-signal rectification only and are not suitable for power rectification or high-current paths.

What board footprint do the SOD-123 diodes need?

Each diode uses a standard SOD-123 surface-mount footprint with two pads for reflow or hand soldering onto an SMD PCB.
