The ZMM5238B-13 is a single, miniature, surface-mount Zener diode featuring low reverse leakage current and a fast switching speed.This diode has a wide range of applications and is suitable for applications requiring a high level of ddt (differential dielectric strength) and immunity to back-shock current. It has a noise immunity rating of up to 65dB. This device also has an EMI (electromagnetic interference) rating of up to 14dB.

The ZMM5238B-13 has a Zener reverse breakdown voltage of 5.6V, which is the voltage at which the scratch-diode current starts to decrease exponentially. The reverse breakdown current of this diode is 4.3mA and the maximum peak surge current is 1.7A. It also features a low reverse operating voltage of 5V and a maximum temperature of 125°C. It is UL certified and RoHS compliant, making it a safe and reliable device.

This Zener diode is commonly used in a wide range of applications, from power supplies and communication systems to automotive electronics and medical equipment. It is particularly suitable for applications that require a robust, high-frequency pulse response, such as circuit protection, signal filtering and voltage stabilization. This diode is also excellent for PCB RF components, where its low capacitance and inductance minimize EMI interference.

The ZMM5238B-13 works in a very simple way. When a voltage is applied to its anode and cathode terminals, the resulting electric field causes electrons to be pushed toward the positive terminal. When the voltage reaches the Zener diode’s breakdown voltage, a high rate of electron flow is initiated; this electron flow returns the voltage to its nominal value. When the voltage exceeding the Zener voltage is quickly removed, the low capacitance of the Zener diode efficiently suppresses the voltage transients in the circuit.

The ZMM5238B-13 is a reliable and versatile device that can be used in a variety of applications. It features a low reverse leakage current, a fast switching speed, high EMI and differential dielectric strength ratings, and a high level of noise immunity. This device is UL certified and RoHS compliant, making it both safe and reliable.
