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.

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

• IEC/EN/DIN EN 60747-5-2 approved

• Options available:

– Leads with 0.4" (10.16 mm) spacing (W00)

– Leads bends for surface mounting (300)

– Tape and reel for SMD (500)

– IEC/EN/DIN EN 60747-5-2 approvals (060)

Applications

• Signal transmission between circuits of different potentials and impedances

• I/O interfaces for computers

• Feedback circuit in power supply
