MM3Z12VB Description

Short technical summary and product information.

The MM3Z12VB is a Zener diode from onsemi designed for voltage regulation and protection applications. It provides a nominal Zener voltage of 12V with a tolerance of ±2% at a test current of 5mA. The device has a maximum power dissipation of 200mW at 25°C ambient temperature, making it suitable for low-power circuits.

 

Key electrical characteristics include a Zener impedance of 23Ω maximum at 5mA and 141Ω maximum at 1mA. Reverse leakage current is 0.09µA maximum at 8V reverse voltage. Forward voltage is 1V maximum at 10mA forward current. The device operates over a junction temperature range of -65°C to 150°C, with a thermal resistance of 595°C/W from junction to ambient.

 

The MM3Z12VB is housed in a surface-mount SOD-323F package (also known as SC-90), which is very small and thin. The package has gull-wing leads for easy soldering. The device marking is HZ. It is Pb-free with Matte Tin finish.
