The SZ1SMA5937BT3G is a 33V Zener diode from ON Semiconductor, part of the SZ1SMA59xxBT3G series designed for voltage regulation in demanding applications. It offers a nominal zener voltage of 33V with ±5% tolerance and a maximum zener impedance of 33Ω. Power dissipation is rated at 1.5W when the lead temperature is held at 75°C (zero lead length), derating to 0.5W at an ambient temperature of 25°C. The device features a low forward voltage of 1.2V maximum at 200mA forward current and a reverse leakage current of 500nA maximum at 25.1V.
This Zener diode is qualified to AEC-Q101 for automotive applications and has an ESD rating of Class 3 (>16 kV) per the Human Body Model, making it robust for harsh environments. It operates over a temperature range of -65°C to +150°C and has a thermal resistance of 50°C/W junction-to-lead and 250°C/W junction-to-ambient.
The part is housed in a DO-214AC (SMA) surface mount package, which provides a low-profile, flat handling surface for accurate placement. It is supplied in tape and reel packaging with a standard quantity of 5000 pieces per reel. The device is RoHS compliant and Pb-free, with an MSL of 1 (unlimited).
