WR0805

Component

SCRSensitive gate8 A800 VMains control

WR0805 is an 8 A sensitive SCR with 800 V blocking ratings and a 200 µA maximum trigger-current specification for low-current gate-drive circuits.

Best for

  • Low-current gate-drive SCR switching
  • Mains-powered appliance controls
  • Igniter control circuits

Avoid if

  • A confirmed compliance status is mandatory
  • The required package variant is unknown
  • Bidirectional AC control requires a TRIAC rather than an SCR

Check before use

  • Verify package and terminal arrangement
  • Confirm thermal path for 8 A RMS operation
  • Validate repetitive dV/dt and surge-current conditions
