The MMBZ5228BS-7 is a Zener diode array designed for use in voltage regulation and protection circuits. The MMBZ5228BS-7 is an eight-diode array with a 5.6V total breakdown voltage rating. The device features an internal diode to provide current limiting as well as an active clamping function to protect the circuit from transients.

The MMBZ5228BS-7 is a double die array with four independent double diode channels. Each channel provides both Zener and transient voltage suppression, which makes it ideal for applications such as DC/DC converters, automotive electronics, communication systems, and industrial equipment.

The device utilizes an epitaxial layer structure with an active clamping circuit to reduce the clamping voltage compared to conventional Zener diodes. The active clamping circuit also helps to reduce the voltage spike amplitudes often associated with ESD protection devices.

The MMBZ5228BS-7 is designed for use with a 7V supply voltage and has a peak current rating of up to 4A and a continuous current rating of up to 1A. It features a thermal shutdown protection which is triggered when the junction temperature exceeds 150°C.

The working principle of the MMBZ5228BS-7 is based on the use of a double die array. The first die is a Zener diode, which provides a voltage reference for the second die, which is a current source. The current source is connected to a drain electrode and a voltage rail, which allows it to draw current from the voltage rail, resulting in a constant voltage across the Zener diode. This reference voltage is maintained even when large spikes of current are passed through the device.

The MMBZ5228BS-7 is ideally suited for use in automotive, communication and industrial applications that require voltage regulation and protection. Its strong clamping capabilities allow it to handle a wide range of transient voltages and currents, making it an ideal choice for applications in which ESD protection is needed. It is also suitable for use in DC/DC converters where a stable output voltage is required.
