SZMM3Z47VT1G

The SZMM3Z47VT1G is a 47V Zener voltage regulator diode from ON Semiconductor, part of the automotive-qualified SZMM3ZxxxT1G series. It is packaged in a compact SOD-323 surface mount package designed for space-constrained applications. The device offers a nominal Zener voltage of 47 V with a tolerance of ±6%, a maximum power dissipation of 300 mW at 25°C ambient temperature, and a forward voltage of 900 mV at 10 mA. Reverse leakage current is limited to 50 nA at 18.9 V, and the maximum Zener impedance is 170 Ω. The diode operates over a junction temperature range of -65°C to 150°C, with a thermal resistance of 416 °C/W (junction-to-ambient on FR-4 board). It features an ESD rating of Class 3 (>16 kV) per Human Body Model and is AEC-Q101 qualified, making it suitable for automotive and other high-reliability applications. The device is Pb-free and the leads are plated with Sn (Pb-Free). The SOD-323 package has a weight of 4.507 mg per unit and is supplied in tape and reel packaging with a standard quantity of 3000 pieces.
