MASMBJSAC18E3

TVS-Diodes are a type of transient-voltage-suppressor device, usually composed of two or more semiconductor layers forming a junction. These are commonly used to protect sensitive electronic circuits from over-voltage and over-current, or electrostatic discharges (ESD). The MASMBJSAC18E3 is specifically designed for Circuit Protection in Automotive, Industrial, Appliance, and Data/Communications Markets.

The MASMBJSAC18E3 provides over voltage protection (OVP) as well as transient suppression and ESD protection. It features a low capacitance, fast response time, and built-in series resistors for noise isolation and voltage protocol hardware protection. The resistors also help to isolate the outputs, reducing the current overload or surge. The combination of OVP, ESD and transient suppression provides dual layer protection and helps to protect the system from any high or low voltage spike.

The unique design of the MASMBJSAC18E3 makes it an ideal choice for a variety of applications. It can be applied to DC-DC converters, power supplies, and any other power electronic circuits where OVP, ESD, and transient suppression is needed. The device is capable of handling high voltage spikes up to 1kV, without compromising system reliability.

The working principle of the MASMBJSAC18E3 is relatively simple to understand. The device contains two diodes, which are connected in a series configuration. The first diode provides OVP protection, while the second provides ESD and transient suppression. The diodes conduct current in the forward direction until the excess voltage is beyond the breakdown voltage of the diodes. When an excess voltage passes through the diodes, they switch into a reverse bias condition, reducing the current and isolating the circuit from any voltage spike. This helps to protect the system from any sudden high or low voltage spikes.

In conclusion, the MASMBJSAC18E3 is a versatile and durable TVS-diode designed to provide over-voltage, ESD and transient protection for a variety of applications. Its circuit protection capabilities help to protect circuits from high or low voltage spikes, and its built-in series resistors help isolate outputs, reducing the current overload or surge. Since its working principle is relatively simple, you can be sure that it provides reliable protection for your circuits.
