TVS diodes are an essential component of any electrical system, providing robust protection against surges, for both electronics and PCs, as well as for data networks. The MSMBJ90AE3 is a widely used TVS diode that provides protection against transient voltage spikes caused by such phenomena as electrostatic discharge, power-crossing, and power-off surge. It is a dual channel, low-power, and low-capacitance diode, making it suitable for a wide range of protection applications.

The MSMBJ90AE3 TVS diode has a non-directional, dual diode configuration, with two terminals (anode and cathode) connected with a common anode. This enables two separate protection circuits, for both anode and cathode, allowing for high levels of protection against surges of up to 30V. The device also features an internal ESD protection function, providing surge protection even at very low voltages.

The MSMBJ90AE3 has a series, polymeric construction, using a special polymer semiconductor body and metal electrodes, which provides excellent protection against both ESD and power surge related transients. The device is available in a variety of packages, from an SC-70 5-pin for surface mount applications to a through-hole 8-pin package, making it suitable for all types of circuit board layout.

The MSMBJ90AE3 is the perfect choice for applications requiring robust protection against transient voltage spikes. The device’s high surge protection capability makes it ideal for use in critical systems, such as in automotive systems, where it can provide effective protection against power surge, ESD, and other transients. In addition to automotive use, the MSMBJ90AE3 is also suitable for other circuitry which need enhanced ESD and surge protection, such as medical devices, portable consumer electronics, and telecoms equipment.

The MSMBJ90AE3 works on the principle of clamping the voltage in order to protect against transient voltage spikes. When the device sees a transient surge voltage, its structure and materials absorb the excess energy, clamping the voltage at its zener breakdown voltage. This absorbs the surge energy and prevents it from reaching the protected component. The device also acts as a shunt, diverting current away from the protected component, thus further enhancing the protection it provides.

In conclusion, the MSMBJ90AE3 is an excellent TVS diode, providing robust protection against transient voltage spikes caused by electrostatic discharge, power-crossing, and power-off surge. Its non-directional, low-capacitance, and dual diode configuration makes it suitable for a wide range of protection applications, while its polymeric construction provides excellent protection against transient surges. The device’s high surge protection capability, and its availability in various packages, make it the perfect choice for any circuit board layout.
