varistors

This article is about varistor construction, characteristics, testing and the often-unappreciated ways varistors can fail.

This article analyzes the V-I characteristic of a varistor and shows it is more appropriate to treat the varistor as a current dependent resistance rather than the conventionally taught voltage dependent resistance. Spice circuit examples are given, based on a current dependent resistance varistor model.

It is a common misconception that any product that complies with IEC 60950-1 will also comply with IEC 62368-1. A key goal of this article is to help readers of IEC 62368-1 understand the underlying safety concerns that the new requirements are trying to address.
