MM3Z4V3B Description

Short technical summary and product information.

The MM3Z4V3B is a Zener Diode from On Semiconductor, part of the MM3Z series. It offers a nominal zener voltage of 4.3V with a tolerance of ±2%, making it suitable for precision voltage reference applications. The device is rated for a maximum power dissipation of 200mW, allowing use in low-power circuits.

 

Electrical characteristics include a zener impedance of 84Ω at 5mA and 470Ω at 1mA, ensuring stable voltage regulation. The reverse leakage current is a maximum of 2.7µA at 1V, and the forward voltage is 1V at 10mA. The diode operates over a wide temperature range from -65°C to 150°C, with a thermal resistance of 595°C/W junction to ambient.

 

The MM3Z4V3B is packaged in a surface mount SOD-323F case (also known as SC-90), which is very small and thin, ideal for space-constrained designs. The matte tin finish is Pb-Free and RoHS compliant.
