Diodes are versatile, practical tools used in a variety of electronic design applications. Zener diodes are a specific type of diode that is commonly used in voltage regulation, signal rectification, and signal conditioning circuits. The SMPZ3923B-M3/84A is a single-part Zener diode that is specifically designed for applications where space is a factor. This article will discuss the application field and working principle of the SMPZ3923B-M3/84A.

General Description

The SMPZ3923B-M3/84A is a single, glass-encapsulated Zener diode with a reverse breakdown voltage of 39V. It is manufactured from a planar resistance-channel layer structure, and is designed to be a compact, low profile device. The diode has a maximum current rating of 100mA and a power dissipation of 500mW. It is hermetically sealed in a SOD-80 flat package, and is designed to be RoHS/ELV compliant.

Application Field

The SMPZ3923B-M3/84A is designed for use in space-constrained applications that require low-profile, reliable voltage regulation. It is particularly well suited for use in mobile devices, such as cell phones and laptops, where size is a critical factor. In addition, it can be used in industrial, automotive, and military applications. The SMPZ3923B-M3/84A can be used in place of more power-hungry alternatives, such as voltage regulators, as it is more efficient and has a lower profile.

Working Principle

The SMPZ3923B-M3/84A operates on the principle of a reverse-biased P-N junction diode. When a reverse-biased current is applied to the diode, it becomes “forward biased”, allowing current to flow from the anode to the cathode. The reverse voltage at which the diode will start to conduct is known as the breakdown voltage, or Zener voltage. In the case of the SMPZ3923B-M3/84A, the breakdown voltage is 39V. The SMPZ3923B-M3/84A is designed to regulate the output voltage to 39V, regardless of input voltage or load. This provides reliable voltage regulation without the need for additional components.

Conclusion

The SMPZ3923B-M3/84A is a single P-N junction Zener diode that is designed for use in space-constrained applications. It has a reverse breakdown voltage of 39V and a maximum current rating of 100mA. It is used in applications such as mobile devices, industrial, automotive, and military. The SMPZ3923B-M3/84A operates on the principle of a reverse-biased diode and is designed to provide reliable voltage regulation without the need for additional components.
