Transient Voltage Suppressors (TVSs) are surge protectors that guard against over-voltage transients that may cause damage to sensitive electronic equipment. Varistors, more commonly known as Metal Oxide Varistors (MOVs), are the most common type of TVS used for over-voltage protection. The VC120603A100DP is a surface-mount varistor that can be used to protect against over-voltage transients.

VC120603A100DP Application Field

The VC120603A100DP is a popular solution for electronic circuits that are vulnerable to over-voltage transients, which is particularly useful for audio and video equipment, computer motherboard circuits, and any device operating off of DC power. The wide voltage range of around 9-440 volts DC makes it especially well-suited for automotive applications, especially those that are exposed to adverse environmental conditions. The Varistor is also useful in sensitive radio and television circuits, since its high surge absorption capacity safeguards the circuits from surges exceeding 2500 volts.

VC120603A100DP Working Principle

The working principle of the VC120603A100DP Varistor is based on the principle of a voltage-dependent resistor (VDR). The Varistor is composed of two electrodes, which are separated by an insulating layer. When an over-voltage transient occurs below the Varistor’s voltage rating, the current will flow through the Varistor and it will act as a resistor, reducing the surge to acceptable levels. When the voltage exceeds the Varistor’s rating, the Varistor will act as a switch, and the current will be shunted away to ground, thus protecting the circuit from damage.

Conclusion

The VC120603A100DP Varistor is a popular solution for over-voltage protection, due to its wide voltage range, high surge absorption capacity, and small size. It is ideal for electronic devices that are exposed to adverse environmental conditions, such as those operating in automotive applications, and it is also suitable for sensitive radio and television circuits. The Varistor works on the principle of a voltage-dependent resistor, and it can be used to protect against over-voltage transients by shunting the excessive current away to ground.
