HCPL-354-000E – AVAGO

The HCPL-354-000E is a high-CMR, single-channel optocoupler manufactured by Avago Technologies, now Broadcom Inc. It features a GaAlAs infrared emitting diode optically coupled to a high-gain integrated photodetector. The device is housed in a 4-pin mini-flat package, enabling high-density board mounting. The HCPL-354-000E provides 3.75 kVrms of reinforced insulation per UL1577 and IEC 60747-5-5, ensuring robust isolation between input and output circuitry. Its high common-mode transient immunity (typically >10 kV/μs) makes it suitable for noisy industrial environments and applications requiring reliable signal transfer in the presence of high voltage transients. The device is specified for operation over a temperature range of -40°C to +85°C and is RoHS compliant. Typical applications include isolated analog and digital signal transmission, programmable logic control, and power supply feedback.
