TVSs (Transient Voltage Suppressors also known as Varistors, MOVs, Surge Arresters or Surge Suppressors) are commonly used components in many power supply circuits. They are designed to protect the circuit from over-voltage and short-circuit conditions, including spikes resulting from power failure, lightning, and other factors. The VDRS10P420AME is a Transient Voltage Suppressor (TVS) module designed to protect power supplies from over-voltage, short-circuit, and other transient conditions.

The VDRS10P420AME\'s application field is in protecting circuits in a variety of power supplies, ranging from automotive systems to computer power supplies. It is suitable for DC/DC, AC/DC, and AC/AC power supply systems. Typical loads include stabilizing control systems and other circuits and devices that are sensitive to voltage transients.

The VDRS10P420AME from Vishay Semiconductors features a high-performance varistor element in a unique thermal design. This innovative design provides an extended discharge time, allowing for improved transient protection and longer equipment life. The unit has an operating temperature range of -55°C to 125°C and can withstand temperatures up to 145°C.

The working principle of Varistors, MOVs, and other TVSs is quite simple. A Varistor or MOV is a low-resistance semi-conductor device which, when an electric current passes through it, produces a voltage spike. When the voltage above the rated maximum voltage of the device exceeds, the current gets stopped and the voltage is clamped to the rated maximum voltage of the device. The unit can then absorb the energy of this voltage spike without allowing it to damage the protected circuit and reset when the over-voltage condition is relieved, thus functioning like an automatic circuit breaker.

The VDRS10P420AME has a maximum clamping voltage of 400V and a peak pulse current of 25A. It comes with an easy to mount design and is suitable for through-hole and surface mount applications. It also has an extremely fast response time with a typical response time of less than 100nS. The unit has a wide operating temperature range and its RoHS compliant construction allows for a long shelf life and improved reliability.

Transient Voltage Suppressors such as the VDRS10P420AME Varistor provide a cost-effective solution for protecting sensitive circuits against voltage transients and short circuit conditions. They have a wide variety of applications in automotive systems, computer power supplies, and other circuits and devices requiring the protection from over-voltage, short-circuit, and other transient conditions. They have a fast response time and a wide temperature range, making them ideal for use in most applications. So if your application needs protection from overloads, power transients, and other events, the VDRS10P420AME is an ideal choice.
