Understanding the Semiconductors Category
The Semiconductors category, identified by ID 3991, resides within the Electronics > Circuit Boards & Components branch of the Google product taxonomy. This classification is intended for foundational electronic components that control or modify electrical currents, serving as the core building blocks for modern digital and analog circuitry.
What Belongs in This Category
This category is specifically for active electronic components used in manufacturing and repair. Examples from the US market include power transistors, voltage regulators, and power ICs. You should also map specialized components such as silicon carbide power MOSFETs, rectifiers, micropower voltage reference diodes, and ultra-low power ASICs here. These items are strictly functional hardware used by engineers or hobbyists to build or modify complex electronic systems.
What Belongs Elsewhere
Do not place items here that fall into neighbouring categories. Specifically, move Printed Circuit Boards, passive components like resistors or capacitors, and electronic filters into their own respective categories. If your products are intended for breadboarding or prototype testing, use the Circuit Prototyping category instead. Furthermore, products like circuit decoders, encoders, or general board accessories belong in their designated neighbouring categories to ensure correct attribute mapping by Google.
Choosing a Subcategory
Always select the most specific subcategory available, such as Transistors, Diodes, Microcontrollers, or Integrated Circuits & Chips, rather than using the parent category ID 3991.
Feed Implementation
Use either the ID 3991 or the full path string: Electronics > Circuit Boards & Components > Semiconductors. Remember that this attribute is optional, though setting it manually prevents Google from miscategorizing your inventory; always use product_type for your internal organizational needs.
