ZMM5265B-7 Discrete Semiconductor Products

The ZMM5265B-7 is a single Zener diode from ON Semiconductor. It offers general purpose protection against power supply variations and power surges. In a voltage regulator circuit, it is used to provide a current limit to protect the circuit from excessive currents. It can also be used for ESD protection in electronic devices and systems. In addition, it can be used to provide isolation between input and output circuits.

The ZMM5265B-7 has a maximum operating temperature rating of 105°C and a maximum reverse voltage rating of 27V. It has a silicon wafer design with a thermally matched clamping structure and an oxide passivation layer. This combination gives it excellent ESD protection with a low clamping voltage.

The ZMM5265B-7 uses a Zener voltage breakdown principle to regulate the output voltage. This principle works by clamping any voltage above the Zener voltage to the Zener voltage level. This is accomplished by the Zener diode, which has an internal breakdown voltage that will cause it to limit the voltage to the Zener voltage once the Zener voltage is reached. This ensures the output voltage is not affected by changes in the input voltage.

The operating principle of the ZMM5265B-7 is based on the reverse breakdown of a pure silicon diode. At a certain reverse voltage, the diode begins to conduct current. This reverse breakdown voltage is the Zener voltage and it can be determined by the internal characteristics of the diode. The ZMM5265B-7 has an adjustable breakdown voltage range from 4.8V to 18V.

The ZMM5265B-7 is designed for surface mount applications and is available in SOD-323 package. It has a low reverse leakage current, low thermal resistance, and fast response time. The device is also RoHS compliant.

The ZMM5265B-7 is ideally suited for use in power supply protection, ESD protection, and voltage regulation applications. It can also be used in automotive, medical, and consumer electronics applications.
