BZX384C10-HE3-18

The BZX384C10-HE3-18 is a single Zener diode from Vishay Semiconductor. This diode has an operating current range of up to 50mA, a Zener voltage of 9.1V, and a Zener Voltage tolerance of 4%. It also has a breakdown voltage of 97V and a noise level of 0.50%; it is rated to operate at temperatures up to 150°C. The diode provides protection against over-voltage, reverse polarity, and electrical surges.

BZX384C10-HE3-18 is designed to mount on a circuit board with soldering or other techniques as designated by the manufacturer. The diode is manufactured with a cylindrical glass body and comes in an SOD-123 form factor. It features an hermetically-sealed glass enclosure for use in severe environmental conditions, such as vibration and humidity. The low-profile design allows it to fit into compact electronic devices.

This Zener diode is suitable for applications such as AC/DC converters, buck switch mode power supplies, automotive systems, and audio amplifiers. Its low leakage current, low noise operation, and high temperature reliability make it ideal for a variety of applications. Additionally, it has an excellent power surge performance for high speed switching and protects sensitive circuits against electrostatic discharge.

The BZX384C10-HE3-18 works by limiting the current passing through it when the applied voltage reaches or exceeds its Zener breakdown voltage. This protects the device or circuit from damage due to over-voltage. When the voltage on the power supply exceeds the breakdown voltage, the current of the device is limited due to the current flowing through the diode. The limitations of the diode depend on the power supply, the diode value, the load on the circuit, and the ambient temperature.

The Zener diode can be used to prevent over-voltage and reverse polarity voltage from damaging the device or circuit. It is commonly used in power supply circuits, voltage regulator circuits, and as a “crowbar” for circuit protection. It is also used in many automotive applications to protect components from overvoltage, undervoltage and reversed polarity. Additionally, the BZX384C10-HE3-18 is widely used in over-voltage, over-current, and surge protection circuits.
