The SZ1SMA5945BT3G is a 68V Zener diode from On Semiconductor, part of the 1SMA59xxBT3G series. It offers a power dissipation of 1.5W (at TL=75°C) and is housed in a compact DO-214AC (SMA) surface mount package. The device features a ±5% tolerance on the Zener voltage and a low forward voltage of 1.5V at 200mA.
This diode is AEC-Q101 qualified, making it suitable for automotive applications. It also boasts an ESD rating of Class 3 (>16 kV) per the Human Body Model, providing robust protection in harsh environments. The operating temperature range spans -65°C to 150°C, and the package is rated UL 94 V-0 for flammability.
Typical applications include voltage regulation, overvoltage protection, and voltage reference circuits in power supplies, automotive electronics, and industrial systems. The device is supplied in tape and reel packaging with a standard quantity of 5000 units.
