The ZMM5258B-7 is a diode designed to operate in single zener mode. It is an ultra-low leakage zener diode that provides superior noise immunity, superior temperature stability and superior reverse voltage capability. It is ideal for applications where low noise and high reliability are essential.

The ZMM5258B-7 is a silicon controlled rectifier (SCR) with a reverse voltage breakdown voltage of 7 V (4.4 V to 12.4 V). It has a maximum forward current of 150 mA and a maximum reverse current of 100 µA. The package size is 5 mm x 3.2 mm and the total power dissipation is 0.3 W.

The ZMM5258B-7 is a device that is used for voltage regulation and for protecting sensitive electronic components from overvoltage and transients. It can be used in many applications such as audio amplifiers, DC-DC converters, voltage regulators, battery chargers, power supplies, and automotive electronics.

The principle of operation of the ZMM5258B-7 is based on the zener effect. When a reverse voltage is applied to the device, the zener voltage of the diode creates a voltage drop across the diode. This voltage drop prevents the voltage at the output to go higher than the zener voltage. When the reverse voltage is applied to the diode, it breaks down and allows a large current to flow which lowers the voltage drop and maintains the desired output voltage.

The ZMM5258B-7 is a low noise and high reliability device, which is ideal for low voltage applications and is suitable for use in harsh environments. It offers excellent noise immunity which means that it is able to suppress high frequency interference signals and provides clean, stable power. It is capable of handling a wide range of temperatures, making it suitable for use in extreme climates. It also has excellent reverse voltage capability, meaning that it can handle input voltages up to 80 V.

The ZMM5258B-7 is a versatile and reliable device for voltage regulation and for protecting components from overvoltage and transients. It is suitable for many applications in both commercial and industrial settings where low noise and high reliability are required.
