WS2815B-4020

Component

12 Vaddressable RGB LED4020 SMDsingle-wireGRBMSL 2a

WS2815B-4020 is a compact 12 V addressable RGB LED for serially cascaded lighting pixels and LED-strip designs.

Best for

  • 12 V addressable RGB LED strips
  • Cascaded decorative and chase-light pixels
  • Compact consumer lighting assemblies

Avoid if

  • The design requires confirmed RoHS, REACH, or lifecycle evidence
  • The controller cannot meet the required one-wire timing or DIN threshold

Check before use

  • Verify 12 V power injection and voltage drop across long chains
  • Send color data in GRB order with MSB first
  • Observe moisture handling requirements: MSL 2a
