DESCRIPTION
This series is designed with discrete diodes for complete isolation. Each diode
can be individually tested according to the electrical characteristics. For transient
voltage protection, two diodes are configured in series with the anode of one
connect to the cathode of the other diode (See Rail Clamp Circuit).
