MASMBJ40CAE3

MASMBJ40CAE3 is a bidirectional Transient Voltage Suppression (TVS) diode and is one of the most popular TVS Diode series on the market today. This diode series, from several types and packages, is designed to protect electronic equipment from transients due to ESD, lightning and other voltage surges. MASMBJ40CAE3 is made of Ultra-Low capacitance and Clamping Voltage of 5.8V.

MASMBJ40CAE3 has a wide range of applications, primarily for the protection of I/O terminals, switches, keyboards, display devices, computer memory storage devices and other components from overvoltage transients generated from ESD, surges, load and line faults, induced lightning and so on. This same diode series is also used in other applications such as computers, telecommunication systems, industrial controls, household appliances, personal handheld devices and other consumer electronics.

The working principle of MASMBJ40CAE3 relies on its diode properties. When voltage surges exceed the diode\'s breakdown voltage, a conductive channel acts as a current limiter since the device reaches its low reverse capacitance and thus limits the current. A single avalanche breakdown voltage ensures the protection of devices under normal and overvoltage conditions.

MASMBJ40CAE3 can be operated in both unidirectional and bidirectional modes depending on the application. The device also helps to reduce the complexity of the circuit, since it does not require any additional components or power supplies. Furthermore, this device is highly reliable since it can tolerate repetitive voltage surges up to 500 amperes.

In conclusion, MASMBJ40CAE3 is a popular TVS diode series and is an ideal solution for protecting electronic equipment from transients due to ESD, lightning and other voltage surges. Its working principle relies on avalanche breakdown and it can be operated in both unidirectional and bidirectional modes. This device offers great protection for computers, telecommunication systems, industrial controls, household appliances, personal handheld devices and other consumer electronics.
