MMSZ3V0T1G

The MMSZ3V0T1G is a Zener voltage regulator diode from On Semiconductor, part of the MMSZxxxT1G series. It offers a nominal Zener voltage of 3V with ±5% tolerance and a power dissipation rating of 500 mW on FR-4 or FR-5 boards. The device is designed for surface mount assembly in the compact SOD-123 package.

Key electrical characteristics include a maximum forward voltage of 900 mV at 10 mA, a reverse leakage current of 10 µA at 1 V, and a maximum zener impedance of 95 Ω at the test current. The diode is rated for an operating temperature range of -55°C to 150°C and has a thermal resistance of 340 °C/W junction-to-ambient.

The MMSZ3V0T1G is AEC-Q101 qualified, making it suitable for automotive applications. It features an ESD rating of >16 kV per the human body model and a flammability rating of UL 94 V-0. The package is void-free, transfer-molded thermosetting plastic with a corrosion-resistant finish and cathode polarity band.

This diode is supplied in tape and reel packaging with a standard quantity of 3000 units per reel. It is RoHS3 compliant, REACH unaffected, and lead-free (Pb-Free). The surface mount SOD-123 package enables high-density board assembly and automated placement.
