Product Description

The onsemi MM3Z18VB is a high quality Zener Diode designed for voltage regulation applications requiring an 18 volt nominal Zener voltage with a power dissipation capacity of 200 milliwatts. This device is packaged in a compact surface-mount SOD-323 package measuring 2.7 mm in length and 1 mm in height, making it suitable for space-constrained circuit boards.

Its ±2% voltage tolerance ensures reliable and accurate voltage clamping under varying electrical conditions. The diode features an extremely low maximum reverse leakage current of 45 nanoamperes at the test current of 5 mA, which supports high efficiency in power-sensitive applications.

Built for durability, the MM3Z18VB operates across a wide temperature range from -65°C to 150°C, suitable for use in industrial, automotive (non-automotive qualified), consumer electronics, and general-purpose electronic manufacturing environments.

The matte tin, lead-free finish complies with RoHS environmental directives, supporting sustainable manufacturing processes without hazardous substances.

This Zener diode’s attributes make it a versatile component in electronic circuit protection, voltage regulation modules, and power supply designs where stable reference voltage is critical.

The diode configuration is single element type optimized for voltage regulation. Its 2-pin configuration and surface mount design enable easy PCB assembly. Voltage regulator Zener type is specifically engineered for precise voltage maintenance.

Choose the onsemi MM3Z18VB for your next electronic design where compact size, efficiency, and reliable voltage regulation are required. Browse additional semiconductor and Zener Diode solutions in the Electronics & Electricals section at EnvMart for more specialized components.
