Note -- these are identical to the Sprague UDN6118A's but have a lower breakdown voltage than the UDN6118A-1's. If using this in a Williams display driver application that requires the UDN6118A-1, make sure the voltage at the display driver is below 85 volts. Often these machines use a 1N4764 to derive 100Volts. This 100Volts is then reduced by an additional 10 volts on the display driver board to provide 90 volts to the display. It is recommended to replace the 1N4764A with a 1N4763A to reduce this voltage to just under the 85 volt threshold.
