Diodes: Zener Diodes

Zener Diodes design engineers Panasonic
Zener diode SMini2-F4-B-mae

The dispersion of Vz characteristics has been drastically improved with FiZ (Four-layer ion-implantation Zener) structure. Suited for constant voltage circuits and ESD protection for signal line of mobile devices (cellphone, DSC), audio-visual systems, etc.
