A Zener diode is a two-terminal electronic component, implemented in a semiconductor diode. It is used to protect circuits against spikes in voltage, such as those caused by lightning or other strong electrical shocks, and is used in a wide range of applications. The BZV55-C2V4,135 is a single Zener diode, defined in the JEDEC standard as a five watt, two ohm, 400V device.

The BZV55-C2V4,135 Zener diode is used in a wide range of applications. It is most commonly used in voltage regulation circuits, allowing a precise voltage to be maintained across a load circuit. When used as part of a voltage regulator, the Zener diode will maintain the output voltage, even if the input voltage varies. This is especially useful in automotive and home electronics applications, where input power supplies can fluctuate considerably.

The BZV55-C2V4,135 Zener diode can also be used in short-circuit protection circuits. In this application, it is used as a "crowbar circuit" to quickly shut off the power to a particular device or circuit. The Zener diode is wired in series with the load, and will begin to conduct when the voltage on the load exceeds the Zener voltage, shorting the input circuit and preventing further current flow.

The device is also used with transistors to create an amplified DC voltage. The Zener diode can be connected in series with the base of the transistor, creating a voltage regulator that will maintain the output voltage at a more stable level than the input voltage. This type of configuration is commonly used to regulate the voltage in laptop computers and other portable devices.

The working principle of the BZV55-C2V4,135 Zener diode is relatively straightforward. The device acts as a normal diode in forward bias mode, conducting current from the anode to the cathode. When reverse biased, however, the Zener diode will begin to conduct once the applied voltage reaches a certain threshold. This voltage is referred to as the "Zener voltage," and is due to the built-in electric field of the diode.

Once the applied voltage exceeds the Zener voltage, the device will begin to conduct in reverse, resulting in a regulated voltage across the diode. This phenomenon is referred to as "avalanche breakdown," and is the key property that makes Zener diodes ideal for use in voltage regulation circuits. The Zener voltage of the BZV55-C2V4,135 is 135 volts, ensuring that the output voltage stays within an acceptable range.

In conclusion, the BZV55-C2V4,135 is a single Zener diode, designed in accordance with JEDEC standards for five watt, two ohm, 400V devices. This diode can be used in many different applications, most commonly in voltage regulation circuits, short-circuit protection circuits, and as an amplifier for DC voltages. While the device is relatively Easy to use, the proper application knowledge and setup is necessary to achieve the desired results.
