The SZ1SMA5917BT3G is a 4.7V Zener diode from On Semiconductor's 1SMA59xxBT3G series, designed for voltage regulation and protection in low-power circuits. With a nominal Zener voltage of 4.7V and a tolerance of ±5%, it delivers a maximum power dissipation of 1.5W when mounted on a suitable copper pad.
Key electrical characteristics include a maximum forward voltage of 1.2V at 200mA, a low reverse leakage current of 2.5µA at 1.5V, and a Zener impedance of 5Ω at the test current. The device also features an ESD rating of Class 3 (>16kV) per the Human Body Model, providing robust protection against electrostatic discharge.
Thermally, the diode operates over a junction temperature range of -65°C to 150°C, with a junction-to-lead thermal resistance of 50°C/W. The package is a void-free, transfer-molded plastic DO-214AC (SMA) designed for surface mount assembly, with a flammability rating of UL 94 V-0 at 0.125 inches.
The SZ prefix indicates AEC-Q101 qualification, making it suitable for automotive applications. Packaging is tape and reel with 5,000 units per reel, and the device is Pb-free as stated in the datasheet.
