USAGE CAUTIONS 1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static electricity when handling. 2. By-pass capacitor of 0.1 μF is used between VCC and GND near device. Also, ensure that the distance between the leads of the photocoupler and capacitor is no more than 10 mm. 3. Avoid storage at a high temperature and high humidity. 6 Data Sheet PN10502EJ05V0DS PS9121 TYPICAL CHARACTERISTICS (TA = 25°C, unless otherwise specified) DETECTOR POWER DISSIPATION vs. AMBIENT TEMPERATURE MAXIMUM FORWARD CURRENT vs. AMBIENT TEMPERATURE 50 Detector Power Dissipation PC (mW) Maximum Forward Current IF (mA) 40 30 20 10 0 20 40 80 85 60 10 20 40 80 85 60 Ambient Temperature TA (˚C) FORWARD CURRENT vs. FORWARD VOLTAGE SUPPLY CURRENT vs. AMBIENT TEMPERATURE 100 12 High Level Supply Current ICCH (mA) Low Level Supply Current ICCL (mA) Forward Current IF (mA) 20 Ambient Temperature TA (˚C) 10 TA = +85˚C +50˚C +25˚C 0˚C –25˚C 1 0.1 1.2 1.4 1.6 1.8 2.0 2.2 10 8 ICCL (VCC = 3.3 V, IF = 10 mA) 6 ICCH (VCC = 3.3 V, IF = 0 mA) 4 2 0 –50 2.4 –25 0 25 50 75 100 Forward Voltage VF (V) Ambient Temperature TA (˚C) OUTPUT VOLTAGE vs. INPUT CURRENT LOW LEVEL OUTPUT VOLTAGE vs. AMBIENT TEMPERATURE 3.5 0.6 Low Level Output Voltage VOL (V) VCC = 3.3 V 3 Output Voltage VO (V) 30 0 100 100 0.01 1.0 40 RL = 350 Ω 1.0 kΩ 2.5 2 4.0 kΩ, 4.7 kΩ 1.5 1 0.5 0 1 2 3 4 5 6 IF = 5.0 mA, VCC = 3.3 V 0.5 0.4 IOL = 16.0 mA 13.0 mA 10.0 mA 6.0 mA 0.3 0.2 0.1 0 –50 Input Current IF (mA) –25 0 25 50 75 100 Ambient Temperature TA (˚C) Remark The graphs indicate nominal characteristics.
