The VCAS120645K900DP is a voltage-dependent circuit protection from Vishay’s TVS - Varistors, MOVs product family. It protects sensitive circuits in telecom, industrial, and consumer applications from voltage transients. This protection device is packaged in an ultra-small, low-profile 1206 chip-array package with an integrated plastic board mount and a wide operating temperature range, making it ideal for a variety of applications.

The VCAS120645K900DP provides protection from overvoltage transient and ESD events by diverting or clamping sudden rises in voltage that may occur on a circuit. The device includes a metal oxide varistor (MOV) element that instantly clamps the voltage when the threshold is exceeded. The VCAS120645K900DP can respond in less than 1 nanosecond, reducing the time and energy of the transient spike. The device also provides electrostatic discharge (ESD) protection with a 2-kV ESD rating per IEC 61000-4-2.

The VCAS120645K900DP is designed to protect low-voltage, low-current systems from overvoltage transients and can handle an allowable peak current of 9.0 A and an operating peak voltage of 45.0 V. Its suggested operating temperature range is –40 °C to +125 °C, making it suitable for a wide range of applications. The low-profile package has a maximum height of 0.95 mm, allowing it to fit into tight, densely packed board layouts. This makes the VCAS120645K900DP an ideal fit for high-density applications such as equipment control boards and instrumentation.

The VCAS120645K900DP is designed to protect lines from transient overvoltage, ESD, and lightning-induced voltage surges. It can also be used to help reduce electromagnetic emissions and provide surge-level protection for low-voltage and low-current systems. Its small form factor makes it an ideal solution for tight board layouts in applications such as industrial electronics, telecom infrastructure, automotive electronics, and consumer electronics.

The VCAS120645K900DP is a vital component in any low-voltage and low-current system that needs to be protected from overvoltage transients and ESD events. Using the device alongside other protection circuits, such as fuses and suppression devices, allows designers to protect their systems from unwanted events. With its excellent thermal performance and fast response time, the VCAS120645K900DP is an ideal protection solution for a wide variety of applications.
