Description
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 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.
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 tape and reel package
