Application Field

The SZMMSZ5244ET1G is a general-purpose Zener diode and can be used in a variety of applications. Its low Capacitance of 4.0 pF and Thermal resistance junction to ambient of 107 °C/W make it ideal for ESD protection. It is also the perfect choice in surge suppressors and voltage clamping applications. The diode also has a low operational breakdown voltage of 5.5V, making it well suited for frequency control designs. Its high surge current rating of 6.0 Amps makes it a useful choice for applications including bypassing, blocking, and voltage clamping.

Working Principle

The SZMMSZ5244ET1G is a Zener diode that operates on the principle of reverse biased P-N junction breakdown. When electric voltage is applied to the diode in reverse bias, an electric field is created in the depletion region of the diode. This electric field starts to increase until the threshold voltage of the diode is reached. At this point, the electrical field is strong enough to break down the electric barrier, causing the current to flow through the diode. The current then decreases as the voltage increases, allowing the voltage to be regulated or clamped at the Zener voltage.

The SZMMSZ5244ET1G Zener diode offers stable current capacitance and thermal resistance that make it ideal for ESD protection and frequency control applications. Its low reverse stand-off voltage and high surge current rating make it a good choice for surge suppressors, bypassing applications, and voltage clamping.
