SZ1SMA5922BT3G

The SZ1SMA5922BT3G is part of the 1.5 Watt Plastic Surface Mount Zener Voltage Regulators series from On Semiconductor. This device features an ESD rating of Class 3 (>16 kV) per Human Body Model, is Pb-Free, and has a flammability rating of UL 94 V-0. The SZ prefix indicates AEC-Q101 qualification for automotive applications.

Electrically, the Zener voltage is 7.5V nominal with a tolerance of ±5%. The maximum Zener impedance is 3 Ω at the test current. Reverse leakage current is limited to 2.5 µA at 6V reverse voltage, and the forward voltage is 1.2V maximum at 200mA forward current.

Thermal characteristics include a power dissipation of 1.5W at lead temperature 75°C (derate 20 mW/°C above 75°C) and 0.5W at ambient temperature 25°C (derate 4 mW/°C above 25°C). Thermal resistance is 50°C/W junction-to-lead and 250°C/W junction-to-ambient. The operating and storage temperature range is -65°C to 150°C. The device is housed in a DO-214AC (SMA) surface mount package with cathode indicated by a notch or band. Maximum soldering temperature is 260°C for 10 seconds.

Compliance includes Pb-Free construction (RoHS implied), AEC-Q101 qualification, and UL 94 V-0 flammability rating. This Zener diode is suitable for voltage regulation, overvoltage protection, and reference voltage applications in automotive and industrial electronics where reliability and compact surface mount packaging are required.
