TVS diodes are an important component of electronic circuits. They are used to protect sensitive electronic components from over voltage due to transient events such as electrostatic discharge (ESD) and electrical surges. The SA85CAHE3/73 is an ESD suppressor diode designed for these applications.

The SA85CAHE3/73 is designed for ESD protection in portable and communications applications. It has a wide operating voltage range and is designed to reduce the peak voltage of transient voltage spikes to a level that is safe for sensitive electronic components. It is suitable for use in supply lines up to 3.6 V with a low capacitance of 0.2 pF.

The SA85CAHE3/73 is designed to provide reliable ESD protection and delivers excellent clamping performance. The device can handle ESD pulses up to 30KV HBM (human body model) and static discharges ranging from 1KV to 15KV. It is equipped with an integrated protection circuit that has highly stable behavior over temperature and supply voltage variations, making it suitable for use in a variety of applications.

The SA85CAHE3/73 works by clamping the voltage generated by a transient voltage event to a safe level. It is designed with a diode structure that consists of a PN junction and an internal FET switch. When the voltage exceeds a certain threshold, the internal FET switch is turned on and the voltage is clamped to a safe level. The ESD protection circuit continues to operate until the transient voltage event is over and the voltage returns to normal.

The SA85CAHE3/73 is designed for use in portable communications and other applications that require reliable ESD protection. It can handle ESD pulses up to 30KV HBM and offers a low capacitance of 0.2pF. Its integrated protection circuit provides highly stable behavior over temperature and supply voltage variations, making it ideal for rugged applications in harsh environments.
