HCPL-181 Phototransistor Optocoupler

The Broadcom® 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 t.

HCPL-181 Features

* Current transfer ratio (CTR: minimum 50% at IF = 5 mA, VCE = 5V)

* High input-output isolation voltage (Viso = 3750 Vrms)

* High collector-emitter voltage (VCEO = 80V)

* Response time (tr: typical, 4 μs at VCE = 2V, IC = 2 mA, RL = 100Ω)

* Mini-flat package (2.0-mm profile) in
