Broadcom Inc. Transistor, Photovoltaic Output Optoisolators ACPL-217-50BE

The ACPL-217 is a DC-input single channel half-pitch phototransistor optocoupler featuring a light-emitting diode optically coupled to a phototransistor, housed in a 4-pin SO package. It offers an input-output isolation voltage of 3000 Vrms, making it suitable for applications requiring high voltage isolation. The device has a typical response time of 2Oºs and a minimum current transfer ratio (CTR) of 50% at an input current of 5 mA. This optocoupler is designed for various applications, including I/O interfaces for programmable controllers and computers, sequence controllers, and signal transmission between circuits with different potentials and impedances. It operates within a temperature range of -55¬8C to 110¬8C and supports a maximum average forward current of 50 mA. The ACPL-217 is RoHS compliant and comes with safety and regulatory approvals, including UL and CSA certifications.
