Diodes are an essential component of most electrical systems. They are used to control the flow of current, either permitting or blocking it depending on their orientation. Zener diodes are a type of diode specifically designed to control the level of current in a circuit. As the current passes through a zener diode, it will reach a level known as its breakdown voltage, where it will “breakdown” and start to flow more freely.

This controlled flow of current makes Zener diodes great for protection in electronic circuits. By choosing the right breakdown voltage, a Zener diode can be used to protect a circuit from both over-voltage and over-current. The MMBZ5237BS-7-F is one such device, combining the capabilities of two zener diodes into a dual-element array.

Measuring just 1.4mm by 0.95mm, the MMBZ5237BS-7-F is designed for use in compact, space-constrained applications. The device consists of two Zener diodes, each with a breakdown voltage of 4.7V. This breakdown voltage is particularly useful for protection from over-voltage in low power circuit design.

The MMBZ5237BS-7-F works by monitoring the voltage level of the circuit it is protecting. As long as the voltage stays below 4.7V, the zener diode array remains in its “off” state and does not interfere with the normal operation of the circuit. If the voltage exceeds 4.7V, then the Zener diodes become activated and divert the excess current away from the main circuit and dissipate it as heat.

The MMBZ5237BS-7-F is ideal for applications where space is at a premium, such as portable electronic devices or circuit boards. Its small size and versatility make it a great choice for protection against both over-voltage and over-current. Furthermore, with a maximum reverse breakdown voltage of 4.7V, it is capable of protecting circuits operating at up to 5V, making it an ideal choice for low power electronics.
