SZ1SMA5921BT3G Description

Short technical summary and product information.

The SZ1SMA5921BT3G is a 6.8V Zener diode from On Semiconductor designed for voltage regulation and overvoltage protection. It offers 1.5W power dissipation at lead temperature 75°C (derated to 0.5W at 25°C ambient) and features a low forward voltage of 1.2V maximum at 200mA. The device provides a Zener impedance of 2.5Ω and reverse leakage current of 2.5 µA at 5.2V.

 

This Zener diode is AEC-Q101 qualified for automotive applications and operates over a temperature range of -65°C to 150°C. It is housed in a surface mount DO-214AC (SMA) package, making it suitable for compact PCB designs. The part is Pb-free.

 

Typical applications include voltage regulation in power supplies, overvoltage protection circuits, and general purpose Zener diode functions in automotive and industrial electronics.
