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.
Key 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
