BZV49-C20,115

A Zener diode, also known as a Zener breakdown diode, is an electronic component that is used to produce a specific voltage level across its terminals. The BZV49-C20,115, is a single Zener diode designed to provide protection from over-voltage, static electricity, and other voltage fluctuations.

The BZV49-C20,115 has a maximum reverse leakage current of 20mA and a maximum zener voltage of 115V. It has a maximum power dissipation rating of 500mW and a wide operating temperature range from -65°C to +150°C. The diode also features a low capacitance and a low forward voltage drop which makes it ideal for high speed circuits.

The most common application of the BZV49-C20,115 is protecting sensitive electronic components from over-voltage and static electricity. The Zener breakdown voltage of the diode is set such that when the input power is greater than the breakdown voltage, the diode will conduct, diverting the excess current away from the electronic components and safely dissipating it. This prevents the components from being damaged due to the over-voltage and static electricity.

The diode can also be used in circuit protection, such as a switching power supply or a motor controller. By limiting the voltage seen by the sensitive electronics, the diode protects them from over-voltage and static electricity, while still allowing the input power to flow. Additionally, the diode can be used in reverse polarity protection. By connecting the diode across the power supply, it will block any reverse current and prevent damage to the electronic components.

The working principle of the BZV49-C20,115 is based on basic diode physics. When the diode is in the forward-biased mode, current is allowed to flow freely in the direction of the arrow on the diodes schematic symbol. When the diode is in the reverse biased mode, no current is allowed to flow and the voltage across the diode is limited by the zener voltage. This zener voltage is predetermined and can be found in the datasheet for the diode.

The BZV49-C20,115 is an excellent choice for protecting sensitive components from over-voltage and static electricity, as well as providing circuit protection and reverse polarity protection. With its wide operating temperature range, low forward voltage drop, and low capacitance, the diode is an invaluable asset in any electronic system, offering reliable and effective protection.
