The SMBJ4747A/TR13 is a single Zener diode produced by Taiwan Semiconductor, an industry leader in semiconductor solutions. The diode has a low reverse breakdown voltage of 4.7V and a low power dissipation of 200mW. It also has an operating temperature range of -25°C to +150°C and a narrow breakdown voltage tolerance of ±3.5%. It has a 200mA maximum forward current, a 400mA max surge reverse current, and a 10μA leakage current.

The device is used in a variety of applications including working as a damper for transient surge protection, a voltage shunt regulator, and an LED switch. As a transient surge protector, the diode helps protect sensitive circuits from voltage transients. It can also be used as a voltage shunt regulator to help keep the output of an electronic circuit at a certain voltage level. Similarly, the diode can be used as an LED switch which turns off or on depending on the voltage level passed through it.

The main working principle of the diode is based on its reverse breakdown voltage. When the diode is forward bias, the current flowing through it is limited by the diode’s forward voltage drop and junction resistance. When the current exceeds this level, the diode begins to conduct and the voltage across it drops steadily. When the voltage reaches its reverse breakdown voltage, the diode will reverse bias and begin to conduct. The current flowing through the diode can then be limited by its reverse breakdown voltage.

In conclusion, the SMBJ4747A/TR13 is a single Zener diode designed for numerous applications. It features a low breakdown voltage of 4.7V and has a wide operating temperature range of -25°C to +150°C. The diode is used as a damper for transient surge protection, a voltage shunt regulator, and an LED switch. Its working principle is based on its reverse breakdown voltage, which is limited by its forward voltage drop and junction resistance.
