The BZV85-C18,113 has a breakdown voltage of 18 V, a maximum reverse current of 1 uA and a maximum peak forward current of 110 mA. It has a thermal resistance of 200 K/W, and its maximum operating temperature is 150°C.

Application Field of BZV85-C18,113

The BZV85-C18,113 is widely used in a range of applications, including power supplies, telecom systems, and audio equipment. Its most common application is to protect equipment against voltage spikes in order to avoid damage. In particular, the BZV85-C18,113 is used as a protective device in power supplies, providing an effective method to suppress overshoots and undershoots. Additionally, it can be used as a safety and signalling device in telecommunication systems to ensure that the transmission lines are properly insulated. Last but not least, it is also used in audio equipment to suppress interference and provide a loud, clean sound.

Working Principle of BZV85-C18,113

The working principle of the BZV85-C18,113 is based on the Zener effect. When a reverse voltage is applied to the diode, electrons from the cathode recombine with holes at the anode, thus generating an electric field. When this electric field reaches a critical value, known as the Zener voltage, it causes a rapid avalanche breakdown of the junction, resulting in a large increase in current flow. By properly controlling this current flow, the BZV85-C18,113 can be used to protect equipment from voltage overshoots and undershoots.

Conclusion

The BZV85-C18,113 is a single Zener diode that is used in a variety of applications. It has a breakdown voltage of 18 V, a maximum reverse current of 1 uA and a maximum peak forward current of 110 mA. Its most common application is to protect equipment from voltage spikes, but it can also be used as a safety and signalling device. The working principle of this diode is based on the Zener effect, which allows it to effectively protect equipment from overshoots and undershoots.
