1. This product requires eight Schottky barrier diodes and two Zener diodes.

We recommend the following components.

Schottky barrier diodes:

MA723 or equivalents

Zener diodes:

MA1150-M, MA8150-M (for positive regulated voltage) or equivalents

MA1100-M, MA8100-M (for negative regulated voltage) or equivalents
