1. Description

The ACPL-217-500E is a DC-input single-channel half-pitch phototransistor optocoupler that contains a light-emitting diode optically coupled to a phototransistor. It is packaged in a 4-pin SO package. The input-output isolation voltage is rated at 3750VRMS. Response time, tr, is 2 μs typically, while minimum CTR is 50% at input current of 5 mA.

2. Features

    1. Current transfer ratio (CTR: 50% (min) at IF = 5 mA,VCC = 5V)

    2. High input-output isolation voltage (VISO = 3750VRMS)

    3. Non-saturated Response time (tr: 2 μs (typ) at VCC = 10V, IC = 2 mA, RL= 100Ω)

    4. SO package

    5. CMR 10 kV/μs (typical)

    6. Safety and regulatory approvals

        - cUL

        - IEC/EN/DIN EN 60747-5-2

    7. Options available:

        - CTR Ranks 0, A, B, C, and D

3. Applications

    1. I/O Interface for programmable controllers, computers.

    2. Sequence controllers.

    3. System appliances, measuring instruments.
