Hot-selling and scarce HCPL-181-00BE Phototransistor Optocoupler SMD Mini-Flat Type spot stock
HCPL-181-00BE Phototransistor Optocoupler SMD Mini-Flat Type spot stock
Product Descriptions
The HCPL-181 contains a light-emitting diodeoptically coupled to a phototransistor. It is packaged in a4-pin mini-flat SMD package with a 2.0-mm profile . Thesmall dimension of this product allows significant spacesaving . The package volume is 30% smaller than that ofconventional DIP type . Input-output isolation voltage is3750 Vrms.Response time,tr,is typically 4 μs and minimumCTR is 50% at input current of 5 mA .
