## Description

A bulk pack of 100 surface-mount 1N4148 signal diodes in SOD-123 package. These are the same fast-switching 1N4148 diodes used in through-hole projects, but in a compact SMT form factor — particularly popular for custom keyboard PCBs where each key switch needs its own diode. Key Features SOD-123 Package – Compact surface-mount form factor Fast Switching – 4 ns reverse recovery time for high-frequency circuits Small Signal Use – Rated for 200 mA forward current 100 V Reverse Voltage – Suitable for most signal-level applications 100 Pieces – Bulk pack for keyboard builds and production runs Specifications Part Number: 1N4148 Max Forward Current: 200 mA Peak Reverse Voltage: 100 V Forward Voltage Drop: ~0.7 V (typical) Reverse Recovery Time: 4 ns Package: SOD-123 (surface mount) Common Applications Custom mechanical keyboard PCBs (key matrix diodes) Signal rectification and clamping Switching and logic protection circuits SMD PCB production and assembly Package Contents 100× 1N4148 signal diodes (SOD-123) Note: This is a surface-mount part. SMD soldering skills are required. Looking for through-hole? See our 1N4148 through-hole 10-pack.
