Selecting TVS Diodes for RS-232, RS-485, and CAN Based on Rated Voltage

**Introduction** In many industrial and automotive applications, protecting interface transceivers from various electrical overstress events is a major concern. Transient Voltage Suppressor (TVS) diodes are commonly used for this purpose as they clamp voltage spikes by creating a low impedance current path. The electrical characteristics of TVS diodes are determined by several process factors. These … Read more
