Bidirectional Zener Diode in Single Package Outline: Two-in-one solution offers cost reduction and board space savings

MM3BZ18

The MM3BZ18 from Diotec combines two opposing 18 V Zener diodes on a single chip. It comes in the tiny SMD outline SOD-323, measuring only 2.5 mm x 1.25 mm and featuring a low profile height of just 1 mm. As such, it is ideally suited for very compact electronic assemblies.

Forming a bidirectional Zener diode, this part allows for positive and negative voltage clipping by just one component. It offers a sharp Zener voltage breakdown of nominal 18 V at 1 mA, a very low leakage current of less than 100 nA at 13 V and up to 200 mW of steady-state power dissipation.

Such device is ideally suited for AC voltage clipping circuits in motor control of brushless power tools, wide range input stages, smart home and IoT applications and further more. The two-in-one configuration enables design engineers to reduce component count, which not only saves board space but also costs for material and assembly.
