The Polytronics 5.0SMDJ36CA is a surface-mount (SMD) transient voltage suppressor (TVS) designed to provide protection from voltage spikes with an operating breakdown voltage that can stand anywhere between 40V and 58.1V. This device is RoHS compliant, meaning it is free from hazardous materials like lead, mercury, and cadmium; and conforms to EU environmental standards. It utilizes a fast, avalanche-capable device structure, making it suitable for use in a wide range of applications, such as automotive, consumer electronics, and industrial systems. The 5.0SMDJ36CA is ideal for protection against voltage transients caused by lightning, load switches, and other sudden voltage changes.
