The operating temperature range is from -40°C to 125°C. It is RoHS compliant and lead-free, making it an excellent choice for applications where reliability, cost and size are important.

Applications

The SMBG5344B/TR13 is designed for a wide variety of applications, including voltage regulation, polarity protection, and clamping. It can be used in switching power supplies, voltage regulators, dc-dc converters, and over-voltage protection circuits. It is also commonly used in automotive, telecommunications and consumer electronics applications.

Working Principle

The SMBG5344B/TR13 works by allowing current to flow between its anode and cathode. When the voltage across the diode exceeds its breakdown voltage, the diode will go into its breakdown region. In this region, a large amount of current can flow at a constant voltage, providing the diode with its voltage regulation properties. The diode is also able to provide protection against high voltages, as the current flowing through the diode will be limited to a certain amount, thus providing a clamping action. Finally, the SMBG5344B/TR13 can also be used for polarity protection, as it will only allow current to flow in one direction.

Conclusion

The SMBG5344B/TR13 is an ideal choice for voltage regulation, clamping, and polarity protection applications. This diode can provide excellent performance in a cost and size efficient package, making it an excellent choice for many applications. With its wide operating temperature range and low maximum current, the SMBG5344B/TR13 is a superior choice for circuit protection needs.
