BROADCOM ACPL-217-50AE Optocoupler, Transistor Output, SOIC, 1 Channel, 50 mA,

The BROADCOM ACPL-217-50AE is a high-performance, 1-channel surface-mount optocoupler designed for reliable signal transmission between circuits of different potentials and impedances. Housed in a compact SOIC package with 4 pins, this DC input half-pitch phototransistor optocoupler features a light emitting diode optically coupled to a phototransistor, ensuring efficient and safe isolation.

With an input-output isolation voltage rated at 3000 V RMS, it provides robust protection for sensitive electronic components. The device offers a typical response time of just 2 μs and a typical common-mode rejection (CMR) of 10 kV/μs, making it ideal for high-speed signal processing and noise-prone environments.
