V33ZU05P

A varistor (sometimes referred to as a voltage-dependent resistor (VDR) or voltage-dependent resistor element (VDR element)) is a component that acts as a nonlinear resistor in response to an applied voltage. Varistors are typically made from zinc oxide and other metal oxide materials, and are used to limit transient voltages. Varistors are characterized by their voltage coefficient, which is the ratio of the voltage change to the corresponding change in the resistance. Varistors are also referred to as transient voltage suppressors (TVS) – typically MOVs (metal oxide varistors) or unidirectional TVS diodes.

The V33ZU05P is a type of monolithic varistor with a 5mm leadless package. The V33ZU05P is designed to protect UART, LVDS and TTL communication lines from transient over-voltages. Itis based on the proven NXP Metal Oxide Varistor (MOV) technology, which provides superior protection compared to conventional gas discharge tubes technology. The V33ZU05P has a breakdown voltage of 38.0 V (maximum) and a maximum current rating of 5A.

The working principle of the V33ZU05P is based on the NXP MOV technology. When an over-voltage occurs on the nodes of the UART, LVDS or TTL communication line, the MOV starts to conduct current. This causes the voltage across the MOV to decrease, allowing it to absorb the transient without creating a momentary disruption in the communication line. The V33ZU05P is designed to provide protection up to 5A, so it can effectively protect sensitive communication lines from over-voltage transients.

The V33ZU05P is ideal for protecting communication lines from transient over-voltages. It is a featured-packed component that offers superior protection compared to a gas discharge tube, and it is compact enough to fit into any circuit board design. The V33ZU05P is designed to provide protection up to 5A, making it a great choice for protecting sensitive UART, LVDS and TTL signaling.
