PoE Design Surge Protection per IEC 61000-4-5

Sponsored by Bourns

Because many applications are located in harsh environments, they require extra protection against damage from power surges, indirect lightning strikes and other transient events. Bourns’ application note presents a surge protection design for a 4-port PoE design that meets IEC 61000-4-5.  It will show how its integrated quad unidirectional diode array specifically designed to provide differential surge protection helps to minimize the board space required to protect PoE supplies and controllers.
