BZX85C33 Description

Short technical summary and product information.

The BZX85C33 is a 33V nominal Zener diode from the BZX85C series manufactured by ON Semiconductor. It features a power dissipation of 1W at 25°C ambient temperature and is designed for general-purpose voltage regulation and clamping applications.

 

Key electrical characteristics include a Zener voltage range of 31V to 35V, maximum Zener impedance of 35Ω at 8mA test current, and a leakage current of 0.5µA at 23V reverse voltage. The forward voltage is 1.2V at 200mA. The device operates over a junction temperature range of -65°C to 200°C.

 

The BZX85C33 is housed in a DO-204AL (DO-41) axial-lead glass package, suitable for through-hole mounting. It is unidirectional and marked with a cathode band. This part is commonly used in power supply circuits, voltage reference modules, and protection circuits requiring a stable 33V reference.
