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).
