The TVS – Diodes devices form a family of Electrostatic Discharge (ESD) protection devices. These devices are used to protect sensitive electronics circuits from the damage caused by Electrostatic Discharge or ESD. The MSMBG28AE3 is a popular TVS – diode. This device is commonly used to provide protection from the ESD pulses that occur in sensitive electronic circuits.

The MSMBG28AE3 is a unipolar diode with a peak reverse voltage rating of 28 volts. This diode has a stand-off voltage of 14 volts. The diode is built in a supermini SOD-123 package. This diode is designed to protect sensitive electronic circuits from ESD damage. The package has 4 leads and is mounted on the PCB with standard through hole technology.

The MSMBG28AE3 is designed for systems with supply voltages up to 24 volts. It provides ESD protection up to 20.0 kV contact discharge, 15.0 kV air discharge, 4.0 kV indirect lightning. The diode also provides a clamping voltage of 27 volts. This feature ensures that the maximum voltage across the protected device is limited to 28 volts.

The MSMBG28AE3 has several applications and benefits. This device is used in UART controller and Serial Digital Interface (SDI) applications. It is also suitable for the protection of inputs to data/control bus lines in automotive and industrial applications. This diode also has low capacitance which is used for driving high frequency signals in an ESD environment.

The working principle of the MSMBG28AE3 is quite simple. It operates as a unidirectional device, only allowing current to pass in one direction, which is from anode to cathode. When an ESD pulse is applied to the device, the diode starts to conduct current, clamping the pulse voltage. This prevents the ESD pulse from damaging the protected board and its components.

The MSMBG28AE3 is an ideal device for protecting sensitive electronic circuits from ESD pulses. The device has a low capacitance that ensures that the high frequency signals are not affected when an ESD pulse is applied. This device is used in a variety of applications and is available in a variety of packages.
