PC900V0NSZXF

The PC900V0NSZXF is a 1-channel PC900V0NSZXF series Digital Output Normal OFF Operation DC Input Photocoupler contains an IRED optically coupled to an OPIC chip. Transistor of detector side in bipolar configuration may be damaged by static electricity due to its minute design. When handling these devices, general countermeasure against static electricity should be taken to avoid breakdown of devices or degradation of characteristics. In order to stabilize power supply line, we should certainly recommend to connect a by-pass capacitor of 0.01µF or more between VCC and GND near the device. The detector which is used in this device, has parasitic diode between each pins and GND. There are cases that miss operation or destruction possibly may be occurred if electric potential of any pin becomes below GND level even for instant. Therefore it shall be recommended to design the circuit that electric potential of any pin does not become below GND level.
