VCAS060309A200DP Circuit Protection

Transient Voltage Suppression (TVS) components such as Varistors, MOVs, are designed to protect sensitive electronic components against overvoltage spikes. In the application field of telecom, consumer electronics, automotive, industrial control and other electronic product fields, they are highly necessary for safety as well as reliable working of circuits.VCAS060309A200DP is a type of TVS product that can provide overvoltage protection for electronic products.

VCAS060309A200DP is a multi-layered Varistor (MLV) with wide operating voltage range from 8.0V to 18V and energy rating of 20J. It is a very small package size (3.0x2.5x1.5mm) that can be applied in telecom, consumer, and automotive fields to enhance electronic products’ safety and performance. VCAS060309A200DP also has excellent mechanical capability, temperature coefficient, clamping voltage coefficient, repetitive peak impact energy, temperature compensation, and stable operation in high temperature over long periods.

Working Principle

Varistors are passive electronic components with two terminals and nonlinear voltage-current characteristics that can be applied in circuit for protection against surges and transients on the power line. The working principle of VCAS060309A200DP is based on its voltage-current relationship with the difference voltage across its two terminal. The key characteristic of Varistors is shown in Figure 1.

When an overvoltage spike occurs on the line as shown in Figure 1, the voltage across the two terminals of VCAS060309A200DP starts to increase. When the voltage reaches its breakdown or clamp voltage, the current between its two terminals starts to increase rapidly and it limits the further rise in voltage across it, thus providing protection to the circuit.

VCAS060309A200DP also incorporates temperature compensation and fast recovery after the transient is over. This feature increases the robustness of the product, and its fast response and excellent voltage clamping capability also ensures its superior transient protection performance.

Conclusion

In conclusion, the VCAS060309A200DP is a multi-layered Varistor specifically designed to protect electronic products against transient overvoltage. It has excellent temperature coefficient, clamping voltage coefficient, repetitive peak impact energy, and temperature compensation, and its fast response and excellent performance also ensures superior transient protection.
