The VDRH14V275ALE is a Transient Voltage Suppression (TVS) device manufactured by Central Semiconductor. This device is an example of a Varistor, or Metal Oxide Varistor (MOV). Varistors are designed to suppress and dissipate electrical transients of high-speed, high-voltage signal effects, by quickly diverting this energy away from key components in order to prevent damage to them. The VDRH14V275ALE is a 275v Metal Oxide Varistor (MOV) designed to provide overvoltage protection in a wide range of consumer and industrial applications.

The primary purpose of a varistor is to protect a circuit from overvoltage conditions. In simplified terms, a varistor is a two-terminal electronic component that behaves much like a resistor with a nonlinear resistance. It works in a similar way to a diode, but unlike a diode, a varistor can protect against both overvoltage and reverse voltage. This makes them particularly useful for protecting against power surges and electrostatic discharges.

The VDRH14V275ALE has a unique breakdown voltage of 275V, making it one of the highest voltage devices in its size class. It is available in an ultra-small SMD package, making it well-suited for space constrained applications. The device has low leakage current, a high energy peak and 1A peak pulse current. Additionally, the VDRH14V275ALE is RoHS compliant, which is important for applications in the medical electronics industry.

The VDRH14V275ALE is designed to provide protection for communication and consumer electronic devices used in automotive, military and aerospace, industrial and instrumentation, lighting, test and measurement, and medical applications. It is commonly used in portable electronics, such as mobile phones, laptops, and tablets. It can also be used in power supplies, motor control systems, voltage regulators, and other high-voltage devices.

The VDRH14V275ALE is a diode with a unique patent pending structure that provides superior performance when compared to existing diode-based products on the market. In normal, low-voltage conditions, the VDRH14V275ALE behaves much like a diode, conducting current in the forward direction. However, when subjected to an overvoltage condition, the device diverts energy away from the protected circuit quickly and efficiently. This helps protect sensitive components from damage due to overvoltage.

When exposed to high-level voltages, the VDRH14V275ALE operates as a current-limiting device. In this state, the device begins to dissipate some of the energy as heat, protecting the components connected to it. This heat is then quickly dissipated to the surrounding environment due to the MOV’s superior thermal management capabilities. The combination of the MOV’s nonlinear current-limiting characteristics, along with its high-level current-limiting capabilities make it an ideal solution for a wide range of protection applications.

The VDRH14V275ALE is a convenient solution for overvoltage protection applications in a wide range of settings. Its simple two-terminal design, robust construction, low-leakage characteristics, and high-voltage, current-limiting capabilities make it an ideal choice for providing overvoltage protection. Additionally, its RoHS compliance makes it a perfect choice for a wide range of medical, industrial, and consumer electronic applications.
