HCPL-181

Agilent HCPL-181 Phototransistor Optocoupler SMD Mini-Flat Type Data Sheet Description The HCPL-181 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 µs and minimum CTR is 50% at input current of 5 mA. Ordering Information Specify part number followed by Option Number (if desired).
