Working Principle

The SMBG5388B/TR13 is based on a Zener diode design. A Zener diode has 2 terminals, the anode and the cathode. The anode is connected to the positive side of the power supply and the cathode to the negative side. When a voltage higher than the Zener voltage is applied to the anode, the diode conducts current in the reverse direction and the voltage across it remains constant. This makes it an ideal voltage reference.

The SMBG5388B/TR13 is enhanced by the addition of a guard ring around the oxide junction of its terminals. This guards against voltage spikes and makes the device more robust and durable in operation. The device also has a low leakage current which enables it to operate for long periods of time without draining the battery. Furthermore, the wide operating temperature range ensures it can be used in a variety of applications.

Conclusion

The SMBG5388B/TR13 is a single zener diode with a wide range of available voltages and an Asymmetric Poly Silicon Guard Ring design. It is widely used in a variety of applications and is an ideal voltage reference. Its low leakage current and wide operating temperature range make it ideal for use in harsh environments and communications. In conclusion, the SMBG5388B/TR13 is a versatile and robust voltage reference device.
