HCPL-181
Phototransistor Optocoupler SMD Mini-Flat Type
Data Sheet
Lead (Pb) Free
RoHS 6 fully
compliant
RoHS 6 fully compliant options available;
-xxxE denotes a lead-free product
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 conven-
tional 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.
