BROADCOM HCPL-0701-000E Optocoupler, SMD, Darlington Output

The BROADCOM HCPL-0701-000E is a sophisticated high-gain optocoupler engineered for sensitive electronic applications. It utilises a low input current LED paired with an integrated high-gain photodetector to achieve an exceptional current transfer ratio, providing reliable electrical isolation and signal transmission.

A key design feature is the separation of photodiode and output stage pins, which facilitates TTL-compatible saturation voltages and supports high-speed operation. The inclusion of a base access terminal offers valuable flexibility, allowing engineers to perform precise gain bandwidth adjustments to optimise circuit performance for specific requirements.

This component is characterised by its robust performance guarantee across a temperature range of 0°C to 70°C, making it suitable for stable operation in varied environmental conditions. Its compact surface-mount design is ideal for modern, space-constrained PCB layouts.
