BROADCOM ACPL-217-500E SOIC-4 Optocoupler, 1 Channel, 50 mA

The BROADCOM ACPL-217-500E is a high-performance, surface-mount phototransistor optocoupler, offering reliable signal isolation and transmission. Designed for demanding industrial and electronic applications, this single-channel device optically couples a light-emitting diode to a phototransistor, providing a safe and effective interface between circuits of different potentials and impedances.

A key feature is its robust isolation capability, with a high input-output isolation voltage of 3000Vrms, ensuring protection against voltage surges and enhancing system safety. It boasts a minimum current transfer ratio (CTR) of 50%, guaranteeing efficient signal transmission even at low input currents. The device also offers excellent common-mode rejection (CMR) of 10kV/µs, minimising interference from electrical noise in demanding environments.

Technical Performance

• Fast Switching: Features a non-saturated response time of 2µs (typical), making it suitable for applications requiring rapid signal processing.
• High Reliability: Approved to rigorous international safety and quality standards, including CSA, UL, and IEC/EN/DIN EN 60747-5-2.
• Compact Design: Housed in a space-saving, half-pitch SOIC-4 package, it is ideal for high-density PCB layouts.

This optocoupler is a versatile solution for protecting sensitive control circuitry, providing level shifting, and eliminating ground loops in complex electronic systems.
