Most common for small logic, power switches, and voltage regulators. SC-70-6 (SOT-363): A smaller version of the SOT-23. DFN / QFN-6: Leadless packages with pads underneath. Often used for transistor arrays or small ICs. 2. Locate Pin 1
This article explains how to interpret those codes and successfully identify your 6-pin SMD IC. 6 pin smd ic marking code
The code A5 is used by at least 20 different ICs from TI, ADI, ON Semi, and others. Most common for small logic, power switches, and
Before decoding, you must correctly orient the IC. Pin 1 is typically indicated by: A or dimple in one corner. A sloped bevel or chamfer along one edge of the case. A bar or line printed next to the code. Decoding Steps Often used for transistor arrays or small ICs
