HCNR201-300E – AVAGO

Overview

The Broadcom HCNR201-300E is a high-linearity optocoupler designed for precise signal isolation in demanding applications. Its critical operational characteristic is the exceptionally low non-linearity, crucial for maintaining signal integrity in analog systems. A key design consideration when implementing the HCNR201-300E is the trade-off between achieving maximum CTR linearity and the forward current required; higher currents improve linearity but increase power dissipation and can impact LED lifespan. This device provides robust galvanic isolation up to 5000 Vrms, making it suitable for environments with significant voltage differentials.
