Diodes - Zener - Single

The BZX79-C9V1,143 is a Single Zener Diode which can be used in a variety of applications. This diode is a three-pin device, consisting of an anode (A), a cathode (K) and a cathode substrate (KS). The anode is the terminal that supplies the voltage, while the cathode is the terminal where the load is connected. This diode also has a buildup region, where the voltage is increased as the current is applied to the terminals. This region is known as the Zener region.

The main purpose of this diode is to provide either a constant voltage or a constant current source, depending on the application. When used as a voltage regulator, the diode can act as a voltage regulator by supplying the current at a constant voltage. This is done by connecting the diode in series with the load. When the voltage at the anode is changed, the current flow through the load is automatically regulated to maintain the voltage. This is useful in applications such as voltmeters and electronic circuits requiring a constant voltage. For example, this diode can be used in the input of an amplifier circuit.

Similarly, the diode can be used to regulate the current through the load. When operating in the reverse bias mode, the diode acts as a constant current source, where the current flow is controlled by the voltage applied to the anode. Thus, the current can be regulated by either raising or lowering the anode voltage, depending on the application. This feature is useful in applications such as switching regulators, where a precise current can be maintained. Furthermore, the diode can also be used in conjunction with other components to protect circuits from excessive currents or voltage.

In terms of electrical specifications, the BZX79-C9V1,143 has a maximum reverse breakdown voltage of 9V and a maximum forward voltage of 1.43V.

The diode is rated for a maximum operating temperature of 125°C.

In conclusion, the BZX79-C9V1,143 is a Single Zener Diode with a wide range of applications in the electronics industry. This diode can act as either a voltage regulator or current regulator, depending on the application. This diode is also capable of handling high currents and voltages, making it a suitable choice for many circuits and systems. Additionally, the device is also designed to have a high level of reliability and is rated for a maximum temperature of 125°C.
