Package

The BZX84-C3V9 is typically packaged in a DO-41 (axial) package type. This package is designed for through-hole mounting and is commonly used for voltage regulation applications.

Pinout

The BZX84-C3V9 is a Zener diode with a pin count of 2. Its primary function is to provide voltage regulation and voltage clamping in electronic circuits. Specifically, it has a Zener breakdown voltage of approximately 3.9V. This diode is commonly used for applications like voltage reference, surge protection, and voltage regulation in power supplies.
The two pins are typically configured as follows:
1. Anode (A) – the negative side, connected to the lower potential.
2. Cathode (K) – the positive side, connected to the higher potential.
In operation, when the voltage across the diode exceeds the Zener voltage (3.9V), it allows current to flow in the reverse direction, effectively maintaining the voltage across it at that level. This characteristic makes it valuable in stabilizing voltage in various electronic circuits.
