SZMMSZ4686T1G Description

Short technical summary and product information.

The SZMMSZ4686T1G is a Zener voltage regulator diode from On Semiconductor, belonging to the MMSZ4xxxT1G series. It provides a nominal Zener voltage of 3.9V with a tolerance of ±5% and a maximum power dissipation of 500mW on FR-4 or FR-5 boards.

 

The diode features a maximum forward voltage of 900mV at 10mA forward current, and a reverse leakage current of 5µA at 2V reverse voltage. It is rated for ESD protection of Class 3 (>16 kV) per Human Body Model. The device is offered in the SZ prefix for automotive applications requiring AEC-Q101 qualification and PPAP capability.

 

Packaged in a surface mount SOD-123 case, it is designed for automated board assembly. The case is void-free, transfer-molded thermosetting plastic with a corrosion-resistant finish. The junction temperature range is -55°C to +150°C, with thermal resistance of 340°C/W junction-to-ambient and 150°C/W junction-to-lead.

 

The device is Pb-free and RoHS compliant. It is also REACH unaffected. The standard package quantity is 3000 pieces on tape and reel.
