Broadcom ACPL-217-500E DC Input Optocoupler, Surface, 4-Pin SOIC

Broadcom ACPL Series Optocoupler, 3000V Isolation Voltage, 50% Minimum Current Transfer Ratio - ACPL-217-500E

This optocoupler provides galvanic separation between input and output for DC signalling in surface-mounted assemblies. It is supplied in an SOIC 4-pin package and is intended for single-channel isolation tasks in industrial control and signal-transfer environments. The device meets recognised electrical safety standards and is provided in high-volume tape-and-reel packaging for automated placement.

Features and Benefits:

• 3000Vac isolation for high-voltage separation and improved safety
  50-600% CTR range allowing flexible input-to-output scaling
  2μs rise time for Rapid signal transmission in fast circuits
  3μs fall time ensuring prompt release of output state
  1.4V maximum forward voltage reducing drive voltage requirements
  -55 to 110°C operating range supporting wide thermal conditions

Applications

• Suitable for isolating control signals in power converters
