The MMSZ3V9T1G from onsemi is a 3.9V Zener diode designed for voltage regulation and protection applications. It offers a power dissipation of 500mW on FR-4 or FR-5 boards, making it suitable for a wide range of low-power circuits. The device features a Zener voltage tolerance of ±5% and a maximum impedance of 90Ω at the Zener test current.
With a reverse leakage current of only 3µA at 1V and a forward voltage of 0.9V typical at 10mA, this diode provides efficient performance. It is housed in a compact SOD-123 surface mount package, ideal for high-density PCB designs. The operating temperature range spans -55°C to 150°C, ensuring reliability in harsh environments.
The MMSZ3V9T1G is AEC-Q101 qualified, making it suitable for automotive applications. It also features an ESD rating of Class 3 (>16 kV) per the Human Body Model, providing robust protection against electrostatic discharge. The device is supplied in tape and reel packaging with 3000 units per reel.
Typical applications include voltage clamping, overvoltage protection, and general purpose voltage regulation in consumer, industrial, and automotive electronics.
