Transient Voltage Suppressor (TVS) devices, such as Varistors, Metal Oxide Varistors (MOVs) and MLVB04V18C0R5 are devices used to protect the wiring and other components of circuits against voltage spikes. These relatively inexpensive devices are an important part of making sure that a system’s power supply remains stable and within acceptable limits.

The MLVB04V18C0R5 is a bidirectional double-sided symmetrical Transil type MLVB04V18C0R5 device from Mersen. This device has a maximum continuous working voltage (Uc) of 4,7 V, a nominal peak voltage (UK) of 18V, and a peak current rating (Iimp) of 5A. It is available in a package size of 1206 and provides a 1500A peak pulse current capability.

In terms of application fields, TVS components such as the MLVB04V18C0R5 are used in transistor circuits, motor control circuits, power supplies, and automotive electronic systems. These components are also used to protect against contact spike transients, induced lightening transients, ESD attacks, and surge overvoltage.

The MLVB04V18C0R5 has a double-sided symmetrical configuration with two bidirectional paths. It is designed to protect the wiring and other components of circuits from voltage spikes. Its symmetrical configuration also ensures that the device is equally effective in both directions.

The MLVB04V18C0R5 has a reverse breakdown voltage rating of 4.7V with a very low leakage current. It operates over a wide temperature range of -40 +125°C. It also features a wide operating voltage range of -30V to +20V, allowing it to suppress wide-ranging high voltages.

When in use, the MLVB04V18C0R5 clamps the transient peak to lower voltage levels and diverts the overvoltage to ground. This helps to protect the circuit from catastrophic damage due to insufficient internal dissipation. The device uses a nonlinear resistance, meaning that it has a much higher electrical resistance at normal operating voltages than at peak voltages. The peak current capability of the device allows it to absorb high transient energy in a slow, controlled manner, further protecting the circuit.

In conclusion, the MLVB04V18C0R5 is a TVS device used to protect the wiring and other components of circuits against voltage spikes. It is used in transistor circuits, motor control circuits, power supplies, and automotive electronic systems. This device is double-sided symmetrical with two bidirectional paths, and features a reverse breakdown voltage rating of 4.7V with a very low leakage current. It clamps the transient peak to lower voltage levels and diverts the overvoltage to ground, using a nonlinear resistance, allowing it to absorb high transient energy in a slow, controlled manner.
