Optocoupler, Transistor Output, Avago TechnologiesThe DC input single and multi-channel phototransistor optocouplers are used for power sequence controller and Input/Output interface applications.The Broadcom HCPL-181-000E optocoupler contains a light emitting diode optically coupled to a phototransistor. It is packaged in a 4-pin mini-flat SMD package with a 2.0 mm profile. The small dimension of this product allows significant space saving. The package volume is 30% smaller than that of conventional DIP type. Input-output isolation voltage is 3750 Vrms. Response time, tr, is typically 4 ms and minimum CTR is 50% at input current of 5 mA.Current Transfer Ratio (CTR: min. 50% at IF = 5 mA, VCE = 5 V)High input-output isolation voltage (Viso = 3750 Vrms)High collector-emitter voltage (VCEO = 80 V)Response time (tr: typ., 4 us at VCE = 2 V, IC = 2 mA, RL = 100 Ohms)Mini-flat package (2.0 mm profile) in tape and reel packageUL approvedCSA approvedIEC/EN/DIN EN 60747-5-2 approvedOptocouplers, Avago Technologies
