Description
The HCPL-814 contains a phototransistor, optically coupled to two light emitting diodes connected inverse parallel. It can operate directly by AC input current. 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 20% at input current of ± 1 mA.

Features
• AC input response
• High input-output isolation voltage (Viso= 5,000 Vrms)
• Low collector dark current (ICEO: max. 10-7 A at VCE = 20 V)
• Current transfer ratio (CTR: min. 20% at IF = ± 1 mA, VCE = 5 V)
• Response time (tr: typ. 4 µs at VCE = 2 V, IC = 2 mA, RL= 100Ω)
• 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 bend for surface mounting (300)
    – Tape and reel for SMD (500)
    – IEC/EN/DIN EN 60747-5-2 approvals (060)

Applications
• Detecting or monitoring AC signals
