ZMM5251B-7 Discrete Semiconductor Products

The ZMM5251B-7 is a single Zener diode designed primarily for general purpose applications, including surge protection and voltage limiting. This diode has a variety of features, including high power dissipation, low thermal resistance, fast switching times, and high temperature stability. Its maximum reverse current is 125mA and its maximum forward current is 250mA.

The ZMM5251B-7 is a general-purpose Zener diode, meaning that it can be used in applications where a wide range of voltage is needed, such as overvoltage protection and circuit testing. It is also used for low voltage clamping, where it can help protect sensitive equipment from overvoltage by clamping the voltage at a safe level. The diode is also used in transient overvoltage protection, where it will momentarily clamp the voltage at a safe level during an overvoltage event.

At its core, the ZMM5251B-7 operates on the same principle as any Zener diode. When reverse voltage is applied to the device, it begins to conduct current. This current is called the Zener current, and it causes a voltage drop across the diode, which is referred to as the Zener voltage. This voltage can be used to provide a stable voltage source in a circuit. The Zener voltage of the ZMM5251B-7 is 7V.

The ZMM5251B-7 has an epitaxial design, which allows the Zener voltage to remain constant even at high temperatures. This feature is indispensable in many applications, as it enables the device to maintain its voltage over a wide range of temperatures. The device also has a fast switching time due to its low capacitance and low recovery time, which allows it to respond quickly to overvoltage events.

The ZMM5251B-7 can be used in a wide variety of applications, from overvoltage protection to low voltage clamping. It is ideal for use in AC/DC converters, motor control circuits, and DC-DC switching regulators. It can also be used in automotive applications for overvoltage protection and voltage limiting, as well as in telecommunications systems for clamping and surge protection. With its high power dissipation, low thermal resistance, and high temperature stability, the device is an excellent choice for a wide range of applications.
