The SZ1SMA5918BT3G is a 1.5W surface mount Zener voltage regulator diode from On Semiconductor, part of the 1SMA59xxBT3G series. It offers a nominal Zener voltage of 5.1V with ±5% tolerance. The device is housed in a void-free, transfer-molded plastic DO-214AC (SMA) package designed for surface mount assembly.
Key electrical specifications include a maximum impedance of 4 Ω at the Zener test current, a reverse leakage current of 2.5 µA at 2V, and a maximum forward voltage of 1.5V at 200mA. The diode is rated for an operating temperature range of -65°C to +150°C and features a thermal resistance of 50°C/W junction-to-lead and 250°C/W junction-to-ambient.
The SZ prefix indicates automotive qualification, with AEC-Q101 compliance and an ESD rating of Class 3 (>16 kV) per the Human Body Model. The package is Pb-free and rated UL 94 V-0 for flammability. Cathode polarity is indicated by a molded notch or band.
