AVR-M1005C270MTAAB is a TVS (Transient Voltage Suppression) device, also known as a varistor, MOV (Metal Oxide Varistor) and ESD protection diode. It is used to protect electronic circuits from electrical transients, such as electrostatic discharge (ESD) and lightning surge. The device is designed to absorb the high peak voltages that can occur when an electronic component is exposed to a transient voltage. The AVR-M1005C270MTAAB is a 27mm square MOV rated for a voltage of 100V and has a current rating of 5A maximum.

Application Field

The AVR-M1005C270MTAAB is designed for use in a variety of applications to protect against transient voltage. It is suitable for use in SCR protection circuits, relay protection, tap changer protection and power supply protection. It can also be used in many other applications, such as automotive, industrial, consumer, and telecom applications.

In automotive applications, the AVR-M1005C270MTAAB can be used to protect the powertrain, communication systems, and other sensitive circuitry from high voltage transient surges. It is also often used in appliances to protect the internal circuitry from transient voltage. In industrial applications, it can be used to protect control boards, sensors, and other sensitive components from destructive voltages.

Working Principle

The AVR-M1005C270MTAAB works on the principle of a varistor, or voltage-dependent resistor. When a voltage above the rated voltage is applied, the device starts to conduct, allowing a current to flow through it and thus dissipating the transient voltage. The device is designed to have a very high resistance in normal operating conditions, which helps protect the circuit from high voltage surges. The device also has an exceptionally fast reaction time, allowing it to react to a transient voltage within nanoseconds.

When the transient voltage passes, the AVR-M1005C270MTAAB switches back to its high-resistance state, allowing the circuit to continue working as normal. The device has a temperature rating of -40°C to +85°C and has a maximum thermal resistance of 0.4°C/W, ensuring that the device can handle high temperatures and still provide reliable protection.

The AVR-M1005C270MTAAB is a versatile device that is suitable for many types of applications and can provide effective protection against transient voltage surges. The device has a high current rating and an exceptionally fast reaction time, making it ideal for protecting sensitive electronic components from high voltage transient surges.
