BAS16 SOT-23 Pin Function Specification

In the SOT-23 package (3 pins), the pinout of the BAS16 is as follows:

Pin Number Pin Name Pin Function Description 1 Anode (A) The positive terminal where the signal or voltage is applied. In a diode, it is the side from which current enters. 2 Cathode (K) The negative terminal of the diode. Current exits the diode here. 3 Shield (S) This pin is often used as a connection to ground or as a shield to protect the diode from external noise. It might not always be utilized depending on the design.

BAS16 Pin Function List

Here’s a breakdown of the functions based on the package and typical usage:

Pin 1: Anode (A) - The anode is the positive side of the diode and must be connected to the higher potential side of the circuit, usually the input voltage.

Pin 2: Cathode (K) - The cathode is the negative side of the diode and is connected to the lower potential, often grounding or through a current-limiting resistor in most circuits.

Pin 3: Shield (S) - This is often a grounding or shielding pin to reduce electromagnetic interference (EMI). It helps in the diode's protection and ensures stability under high-frequency operations.
