SZMM3Z3V9T1G Description

Short technical summary and product information.

This is a Zener diode from On Semiconductor's SZMM3ZxxxT1G series, designed for voltage regulation in space-constrained applications. It offers a nominal Zener voltage of 3.9V with ±5% tolerance and a maximum power dissipation of 300mW on a standard FR-4 board.

 

Electrical characteristics include a Zener impedance of 90Ω (max), forward voltage of 900mV at 10mA, and reverse leakage current of 3µA at 1V. The device is ESD rated to Class 3 (>16kV) per HBM.

 

The diode is packaged in a void-free transfer-molded plastic SOD-323 case, measuring 1.7mm x 1.25mm x 0.9mm and weighing 4.5mg. It is rated for operation from -65°C to 150°C junction temperature, with a junction-to-ambient thermal resistance of 416°C/W. The leads are plated with Sn (Pb-Free) and the product is Pb-Free compliant.

 

Designed for surface mount assembly, it is supplied in tape and reel packaging with 3000 units per reel. The device is AEC-Q101 qualified (for automotive applications) and supports maximum soldering temperature of 260°C for 10 seconds.
