TVS (Transient Voltage Suppressor) diodes are a type of semiconductor which is designed to protect sensitive electronic circuits from high- and low-energy voltage or current levels. SA28CHE3/73 is a TVS diode designed to protect against ESD in a range of low-voltage, high-frequency applications. This diode offers excellent protection and performance characteristics, making it ideal for consumer and industrial applications.

Application field of SA28CHE3/73
SA28CHE3/73 is designed for ESD protection of microcontrollers and peripherals from an ESD event to ensure proper operation in low-voltage, high-frequency applications. This diode also provides surge and transients protection for automotive, telecoms, and other consumer and industrial applications.

Working principle
SA28CHE3/73 works by diverting electrical surge currents away from the sensitive component. This diode is permanently connected between the inductive circuit and the ground, preventing high-energy disruptions from propagating into other parts of the circuit. During a high-energy event, the diode will activate by providing a low impedance path and allowing current to flow through it. This reduces the voltage seen by other circuits and components, protecting them from potential damage. The diode also prevents high-energy events from propagating back into other sections of the circuit.

SA28CHE3/73 offers excellent protection and performance characteristics. It has high peak current handling capability and low capacitance, making it suitable for use in a wide range of frequencies. Its reverse blocking voltage of 18V allows it to protect against reverse voltage spikes. The device also features a fast response time to protect against transients and surges. Finally, the diode is humidity-resistant, rugged, and flexible, making it ideal for use in industrial applications.

SA28CHE3/73 is a high-reliability TVS diode that offers excellent protection and performance characteristics. It is designed to protect sensitive electronic circuits from high- and low-energy voltage or current levels, allowing it to be used in a range of consumer and industrial applications.
