The SMBJ4736/TR13 is a Zener diode intended for use in applications which require voltage protection, fast switching, and high temperature operation of up to 175°C.

These diodes are mainly used in applications where transient voltages need to be limited during power on/off or in over voltage situations, for example in order to protect boards and electronic parts from transient voltages typically generated by capacitors, coils and other components. They are most commonly used in mobile phones, communications equipment, laptop and desktop computers and other electronics.

The working principle of the SMBJ4736/TR13 diode is based on the PN junction diode and its ability to control the voltage at a certain level. These diodes have a higher reverse voltage and have a low forward voltage drop. When the reverse voltage is greater than the Zener voltage, the PN junction breaks down creating a low resistance path that allows current to flow. The junction holds this voltage until it is removed.

These diodes have a power dissipation of 500mW and offer a total capacitance of 8pF. They are also capable of handling an extremely high surge current of 200A and operate between a -55°C to +175°C temperature range making them highly suitable for use in a wide range of industrial applications.

SMBJ4736/TR13 diodes are capable of operating at a maximum voltage of 47V, making them ideal for applications that require protection against overvoltage, such as in automotive and industrial settings. In addition, they feature a fast response time, making them suitable for high-speed switching applications, while providing excellent current-carrying capabilities.

The excellent performance characteristics of the SMBJ4736/TR13 make it a great choice for a wide variety of applications. It is often used in automotive and industrial applications such as power supplies and electric vehicles, as well as in computing, consumer electronics and mobile devices.
