The KID65003AP chip is a transistor assembly consisting of seven seven Darlington transistors.It is designed to work as a key with an output voltage of up to 50 volts and a maximum current in a load of up to 500 mA.The analogue of this chip is ULN2003A.

The chip has varieties called KID65001AP/AF, 65002,65004,they all differ from each other by an input resistor or by connecting different resistors in the assembly and also by connecting a zener diode.

Such a chip can be found on the control boards of washing machines
