The DC input single and multi-channel phototransistor optocouplers are used for power sequence controller and Input/Output interface applications.
The Broadcom HCPL-181 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 package
For products that are Customized and under Non-cancellable & Non-returnable, Sales & Conditions apply.
