Transient voltage suppression (TVS) devices are designed to protect against short duration transient fluctuations in an electronic system\'s voltage supply, usually from transient overvoltage events such as electrostatic discharge (ESD) and voltage surges. TVS devices come in many different shapes and sizes, offering a variety of protection levels and characteristics. One such device is the V47ZS20P, which is a non-longitudinal multilayer varistor.

Varistors are also referred to as voltage dependent resistors (VDRs), as their resistance changes depending on the input voltage. Varistors are normally used in an off-state, with no current flowing through them. When the input voltage exceeds the device’s clamping voltage, the varistor begins to conduct, allowing current to flow in either direction.

The V47ZS20P is a multilayer varistor that is rated for a peak pulse power of 2500 watts, a peak pulse current of 15.9 A (8/20 μs), and a peak pulse current of 10 A (8/20 μs) at a clamping voltage of 19 V. It also has an operational temperature range of -55°C to +125°C, and a storage temperature range of -55°C to +150°C. The device offers superior ESD protection when used between a power supply and an I/O port, which ensures that any ESD events are contained and do not cause any damage to sensitive circuitry.

The V47ZS20P has a low leakage current, typically less than 10μA at 25°C, ensuring that the device is not constantly drawing unnecessary power. Furthermore, the device is very compact, measuring just 3.9 x 3.5 x 0.5mm (0.15 x 0.14 x 0.02 inches). This makes the device an ideal choice for space-sensitive applications such as those found in consumer electronics devices.

The device is housed in a RoHS-compliant package, making it easy to integrate into any design. The V47ZS20P is also reliable and durable, with its maximum surge lifespan of 200 surges and X2 (common mode) surge life of 1000 surges, both at 8/20 μs pulse width, making it suitable for long-term applications.

In summary, the V47ZS20P is a multilayer varistor that offers excellent ESD protection in a variety of applications. Its compact size, low power draw, and high reliability make it an ideal choice for space-sensitive designs. Furthermore, its wide operating temperature range and RoHS-compliant package make it easy to integrate into any design.
