Diodes play a very important role in many electronics applications. They act as switches and rectifiers, limiting current flow in one direction, and allowing it to flow in another. Usually, a diode is made of semiconductor material, and has two terminals; a P-type (positive) and N-type (negative) regions. A Zener diode is a type of diode which is tailored to offer a particular voltage drop across it, making it suitable for voltage regulation, biasing transistors, and protecting against overvoltage.

JANS1N6309D is a single Zener diode offered by many manufacturers. It is capable of regulating a 12 volt source to a 7.5 volt output. The device comprises a silicon chip enclosed in a DO-41 (2.54mm x 6.35mm) plastic package, and presents very low forward voltage drop. It is designed to mount onto an FR-4 Printed Circuit Board (PCB).

The JANS1N6309D has a rated maximum power of 500mW, meaning it can provide steady current in the region of 67mA. Characteristics include a zero-reverse recovery time, meaning that when the voltage passes through the Zener voltage, the onset of reverse current will not be affected. It also features a ‘knee’ of 1.5 volts, meaning that for small variations in the input voltage, up to 1.5 volts, there will be little variation in the output voltage.

JANS1N6309D diodes have a range of applications. These include AC-DC and DC-DC power supplies, DC-DC Choppers and Off-Line Switchers, Driving Circuits, Audio/Visual Products, Battery Chargers, Anti-static and Electrostatic Discharge (ESD) protection, Security and Alarm Systems, and Motor Speed and Torque Control.

The working principle of the JANS1N6309D is based on the Zener effect theory. This states that when forward biased, the diode will appear to be a normal diode. In the reverse biased direction, however, the application of a voltage greater than a specific value known as the Zener voltage will cause a ‘breakdown’ of the barrier between the N-Type and P-Type silicon. This causes an avalanche breakdown which leads to a surge of current.

The circuit above shows the basic configuration of a JANS1N6309D Zener diode. Here, it is connected in the reverse direction across the power supply. It thereby allows maximum reverse current. When the voltage of the input supply rises above the Zener voltage of the diode, an avalanche breakdown occurs, providing the required regulated output of 7.5 volts. The 10Ω resistor limits the surge current.

In summary, the JANS1N6309D is a single Zener Diode used in a range of electronic applications. It is designed to regulate 12v input sources to 7.5v output, and can dissipate up to 500mW in the process. It is designed to mount onto a PCB and is capable of handling up to 67mA. Its operation is based on the Zener effect theory, which states that applying a voltage greater than a pre-specified value in the reverse direction causes an avalanche breakdown of the N-Type/P-Type silicon barrier.
