LED of channel 1 is switched to ”ON”. At Tr-output of channel 2 a voltage is applied and one can measure a current between emitter and collector. This is leakage current (at IF = 5 mA, VCEO = 24 V).

Data Sheet PN10202EJ03V0DS 9 PS2841-4A,PS2841-4B (4) Cautions • Fluxes Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent. 2. Cautions regarding noise Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between collector-emitters at startup, the output transistor may enter the on state, even if the voltage is within the absolute maximum ratings. USAGE CAUTIONS 1. Protect against static electricity when handling. 2. Avoid storage at a high temperature and high humidity. 10 Data Sheet PN10202EJ03V0DS 4590 Patrick Henry Drive Santa Clara, CA 95054-1817 Telephone: (408) 919-2500 Facsimile: (408) 988-0279 Subject: Compliance with EU Directives CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive 2003/11/EC Restriction on Penta and Octa BDE.
