SZMMSZ4V3T1G Description

Short technical summary and product information.

The On Semiconductor SZMMSZ4V3T1G is a Zener voltage regulator diode from the SZMMSZxxxT1G series, designed for surface mount applications. It offers a nominal Zener voltage of 4.3V with a tolerance of ±5% and a maximum Zener impedance of 90 Ω at the IZT test current.

 

This device is rated for a total power dissipation of 500mW on an FR-5 board, with a power derating factor of 6.7 mW/°C above 75°C. It features a maximum forward voltage of 900mV at 10mA and a reverse leakage current of 3 µA at 1V. The operating temperature range spans from -55°C to 150°C.

 

The SZMMSZ4V3T1G is housed in a void-free, transfer-molded SOD-123 plastic case with a corrosion-resistant finish. It is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications. The device has an ESD rating of Class 3 (>16 kV) per the Human Body Model and is UL 94 V-0 flammability rated.
