The 1N5372BE3/TR13 is a single Zener diode, commonly used to provide regulation of voltage levels and overvoltage protection. It is specially designed to protect transistors and other components from damage due to overvoltage conditions. The diode is of relatively low cost and simple in design, making it a very versatile and reliable solution for a wide range of applications.

Application Field

The 1N5372BE3/TR13 is used in many applications where a stable voltage float and a tight regulation of voltage is necessary:

• Replacing surface mounted Zener diodes.
• Circuit protection of transistors and other components.
• Regulation of voltage levels.
• AC-DC rectification.
• DC-DC voltage conversion.
• Digital switching circuits.
• Automotive, industrial, and aviation electronic systems.

Working Principle

The 1N5372BE3/TR13 is designed to act as a switch for higher or lower voltages in an electrical circuit with a fairly uniform process that takes place in an almost linear fashion over a wide range of voltages. The diode consists of two parts: an anode and a cathode. When the anode is more negative than the cathode, it carries current. This allows current to flow in the opposite direction, which serves to produce the desired voltage clamping effect. Otherwise, when the anode is more positive than the cathode, the diode is blocked and no current can flow. The operating temperature of the 1N5372BE3/TR13 ranges from -65°C to 125°C, with a nominal breakdown voltage of 37V. It has a maximum reverse leakage current of 250μA and a high surge-current capability.

Conclusion

The 1N5372BE3/TR13 is an ideal single Zener Diode for applications where a specific regulated voltage needs to be maintained over a wide range of temperatures. Its relatively low cost and simple design make it a reliable and powerful choice for many applications including circuit protection, AC-DC rectification, and DC-DC voltage conversion. With its tight voltage regulation and surge-current capability, the 1N5372BE3/TR13 is the go-to for many power systems.
