Storage Temperature -55° C to +125° C Operating Temperature -55° C to +100° C Input-to-Output Isolation Voltage
(1)(2) ± 15 kVDCLead Soldering Temperature (1/16” (1.6 mm) from case for 5 seconds with soldering iron)
(3) 260° C Input Diode Forward DC Current
(4) 150 mA Reverse DC Voltage 3 V Power Dissipation
(5) 200 mW Output Photosensor Collector-Emitter Voltage OPI120 OPI123 25 V 20 V Power Dissipation
(6) 250 mW Collector-Base Voltage OPI120 25 V Emitter-Collector Voltage 5 V
Notes:(1) Measured with input and output leads shorted in air with a maximum relative humidity of 50%. If suitably encapsulated or oil-immersed, the isolation voltage is increased to 25 kV minimum. (2) UL recognition is for 3750 VAC to 100° C. (3) RMA flux is recommended. The duration can be extended to 10 seconds maximum when flow soldering. (4) Derate linearly 2.0 mA/°C above 25°C. (5) Derate linearly 2.67 mA/°C above 25°C. (6) Derate linearly 3.33 mA/°C above 25°C.
