MM3Z4V3ST1G Description

Short technical summary and product information.

The MM3Z4V3ST1G is a 4.3V Zener diode from On Semiconductor, part of the MM3ZxxxST1G series. It is designed for voltage regulation in space-constrained applications such as cellular phones and portable electronics. The device offers a nominal Zener voltage of 4.3V with a ±3% tolerance, and a reverse leakage current of 3 µA at 1V. Forward voltage is 900 mV at 10 mA, and maximum impedance (Zzt) is 90 Ω.

 

Power dissipation is rated at 300 mW on an FR-4 board and 500 mW under steady-state conditions at 25°C. The device operates over a junction temperature range of -65°C to 150°C. Housed in a SOD-323 (SC-76) surface-mount package, it is supplied in tape and reel packaging with 3,000 units per reel. The MM3Z4V3ST1G is RoHS compliant and Pb-Free, making it suitable for lead-free soldering processes.
