A varistor or voltage-dependent resistor (VDR) is an electronic component made up of a semi-conductor material with a large electric resistance to voltage fluctuations. They are primarily used for protection from voltage transients or surges, as they reduce the excessive voltage to a safe level. Typical application fields include automotive, industrial, medical, LED lighting, and telecom. The B72214S1140K551 is a varistor device widely used for transient voltage protection.
The structure of the B72214S1140K551 more resembles a diode than a resistor. It consists of four silicon chips mounted on an aluminium oxide substrate which is then encapsulated with epoxy resin. The substrate is resistant to mechanical and environmental stress, and the contacts offer good electrical connection. The varistor follows a symmetrical voltage/current response, with a “knee” that defines its minimum and maximum working values. The B72214S1140K551 is designed to respond in approximately 1ms when subjected to high transients.
Working Principle
Varistors are non-linear devices, a feature which allows them to offer protection from high voltages or current transients. The silicon chips and the substrate provide the varistor with a negative temperature coefficient, meaning that current is diverted away from the protected components during a transient, rather than flowing through them as it would in a linear device. The B72214S1140K551 has a low clamping voltage, mounted on an aluminium oxide substrate, giving it a high level of resistance to thermal and electrical shock. The symmetrical response is designed to protect against both positive and negative transients, with good performance all the way up to its breakdown voltage.
Application Fields
The B72214S1140K551 is designed to offer protection from transients of medium to high voltages and currents, typically up to 1.6A and 1.2kV. This makes it ideal for a wide range of protection applications, including automotive, industrial, medical, LED lighting, and telecom equipment. In such applications, they are often used as part of a circuit protection system, as they provide a low impedance path when a transient occurs, preventing excessive voltage or current flow into the sensitive components. They also ensure that the transient is dissipated before it reaches the protected equipment, allowing the system to continue operating at a safe level.
The B72214S1140K551 is ideal for high reliability applications where voltage transients are common, such as in motor driven or electro-mechanical systems, and can be used in combination with other circuit protection devices. The high surge capability and wide operating temperature range make it suitable for a variety of environments, from automotive electronics to industrial automation.
The B72214S1140K551 from TDK Corporation is a widely used varistor, offering reliable protection from transients or surges up to 1.2kV and 1.6A. It is mounted on an aluminium oxide substrate, giving it high resistance to thermal and electrical shock, and a symmetrical voltage/current response offers protection against both positive and negative transients. With a wide range of applications, from automotive, industrial, medical and LED lighting, it is the ideal varistor for systems where reliable protection from transient voltage is required.
