 Features
  • High ON-state current capability
  • Low off-state leakage
  • Ability to auto-reset to off-state if LED heals
  • Low and repeatable response time
Key Requirement
  • Low ON-state resistance, high OFF-state resistance and high reliability
Benefits
  • High reliability, enables longevity of string and fixture
  • Capable of operating in high current strings
