SMBJ40A-M3/5B

The SMBJ40A-M3/5B is a 3-pin bidirectional transient voltage suppressor diode designed to protect sensitive electronic components from overvoltage and electrostatic discharge (ESD). This diode is part of a larger family of voltage-variable suppression products from ON Semiconductor that offer a variety of breakdown voltages, surge capability, and package size. This particular diode is rated for a breakdown voltage of 40V and can handle ESD pulses up to 8A.

Transient voltage suppression diodes are components that can protect sensitive electronic components from voltage and current spikes. A diode is a two-terminal electronic component that is made up of a semiconductor material that will conduct voltage when forward biased or block current when reverse biased. In the case of the SMBJ40A-M3/5B the diode will conduct current when a voltage greater than 40V is applied to it. The diode is then able to dissipate this energy and reduce the voltage to a safe level before it can damage any sensitive components.

The application fields for the SMBJ40A-M3/5B diode include consumer electronics, industrial, automotive, and telecommunications applications. This diode is most suitable for applications that require ESD protection. This diode is also useful for providing overvoltage protection and protecting digital logic components against power surges. It is also used to protect medical devices and data lines. This diode is available in surface mount and through-hole packages, which makes it suitable for a wide variety of applications.

The working principle for the SMBJ40A-M3/5B diode is the same as with other transient voltage suppression diodes. When a voltage greater than the rated breakdown voltage is applied, the diode will conduct current, dissipating the energy and reducing the voltage to a safe level before it can damage any sensitive components. The diode is then able to reset itself and be ready to act again when another voltage spike is applied.

In summary, the SMBJ40A-M3/5B is a 3-terminal bidirectional transient voltage suppression diode designed to protect sensitive electronic components from voltage and current spikes. This diode is rated for a breakdown voltage of 40V and can handle ESD pulses up to 8A.
