BZX55A12 Description

Short technical summary and product information.

The Thomson-CSF BZX55A12 is a silicon planar Zener diode designed for voltage regulation applications. It offers a power dissipation of 500mW at 25°C and a nominal Zener voltage of 12V with a tight tolerance of 1%.

 

This diode operates with a working test current of 5mA and exhibits a low reverse leakage current of 1µA maximum at 9.1V. The junction temperature can reach up to 200°C, with a storage temperature range from -65°C to +200°C. The component is supplied in a DO-35 glass package with axial termination.

 

Key electrical characteristics include a forward voltage of 1.3V maximum at 100mA and a Zener impedance of 90Ω maximum at the working test current. The die itself measures 450 x 450 µm with an anode pad size of 235 x 235 µm and a thickness of 200 µm. The back metal composition is gold, and the top metal is aluminum, indicating high reliability construction.

 

This component is suitable for various voltage regulation circuits where precise voltage control is required. Its robust construction and specified electrical parameters make it a reliable choice for demanding applications.
