TVS or transient voltage suppressors and MOV or metal oxide varistors products have been used in electrical circuit protection for over 50 years. These products are designed to limit the rise of voltage above a certain threshold, and protect the components in a given circuit from any transient voltages that may cause damage. The VDRH14V320BKE is one of the most popular TVS - MOVs with a voltage range that covers a wide range of applications.

The VDRH14V320BKE is an 8-pin, conventional surface-mount device with a Zener diode circuit designed to protect electronic circuits against voltage transients caused by electrostatic discharge, inductive switching and lightning.¹ It is designed to limit the rise of voltage above a predefined threshold up to 14V with a peak pulse current of 320A, and provides protection for components and data lines (such as high speed data lines) in automotive, industrial, computer and telecommunications applications.

The operation of VDRH14V320BKE is based on the charging of its Zener diode junction by the transient current. As the applied voltage exceeds a certain level, the current is diverted away from the device by laser-trimmed Zener diodes. This diverts the surplus current away from the product, thereby limiting the overvoltage generated by the transient voltage. The clamping voltage of the product is determined by the number of Zener diodes and the magnitude of the transient current that flows through the device.

The product features an increase in clamping voltage and a decrease in leakage current as the temperature increases, which helps protect the circuit from any overvoltage transients, as well as keeping the device leakage current at a low level. It also has a very low capacitance and is designed for high-speed data lines.

The VDRH14V320BKE is suitable for a variety of applications and can be used in automotive, industrial, computer and telecommunications applications, as well as other applications where transient voltages need to be limited. It is capable of providing reliable protection against ESD, power surges, inductive switching and lightning. The product is designed to be used in voltage protection circuits, such as ESD transient voltage suppressors (TVS) and MOVs.

In summary, the VDRH14V320BKE is a high performance 8-pin conventional surface-mount TVS - MOV product that can be used in a wide variety of applications. It is designed to protect circuits from voltage transients and overvoltage, and is capable of providing reliable protection against ESD, power surges, inductive switching and lightning. ¹ [https://www.littelfuse.com/products/varistors/vdrh14v320bke-dr.aspx]
