Smd Codes Databook 2021 -

For diodes, the cathode mark; for transistors, the pin configuration (1=Base, 2=Emitter, 3=Collector or variations). Some manufacturers swap pins, and the databook highlights these differences.

Based on forum discussions from 2021, these codes cause the most headaches: smd codes databook 2021

Before we delve into the databook, we must understand the language. An SMD code is a short alphanumeric string printed on the body of a surface-mount component. Because the component’s physical space is too small for a full part number (like BC847B or LM358 ), manufacturers use a proprietary or standardized marking code. For diodes, the cathode mark; for transistors, the
