Agilent HCPL-817
Phototransistor Optocoupler
High Density Mounting Type
Data Sheet
Features
• Current Transfer Ratio
(CTR: min. 50% at IF = 5 mA,
VCE = 5 V)
• High input-output isolation voltage
(Viso = 5000 Vrms)
• Response time (tr: typ., 4 µs at
VCE = 2 V, IC = 2 mA, RL = 100 Ω)
• Compact dual-in-line package
• UL approved
• CSA approved
• VDE approved
• Options available:
– Leads with 0.4" (10.16 mm)
spacing (W00)
– Leads bends for surface
mounting (300)
– Tape and reel for SMD (500)
– VDE 0884 approvals (060)
Applications
• Signal transmission between
circuits of different potentials and
impedances
• I/O interfaces for computers
• Feedback circuit in power supply
Description
The HCPL-817 contains a light
emitting diode optically coupled to
a phototransistor. It is packaged in
a 4-pin DIP package and available
in wide-lead spacing option and
lead bend SMD option. Input-output
isolation voltage is 5000 Vrms.
Response time, tr, is typically 4 µs
and minimum CTR is 50% at input
current of 5 mA.
