Application Scenarios & Design Considerations

4A TRIACS

Alternative Part Number

  • BTA08-600B --: 8A 600V snubberless triac in TO-220, same package and pinout, higher current rating provides margin over the 4A original.
  • Q4008L4 --: 8A 400V triac in TO-220 isolated package, comparable gate sensitivity and voltage class suitable for 700V-class AC switching designs.
  • MAC08BT --: 8A 600V triac in TO-220, widely available alternative with similar gate trigger characteristics for general AC power control.
  • BTA06-600B --: 6A 600V snubberless triac in TO-220, similar current and voltage rating, widely available and pin-compatible for most 4A triac applications.
  • Q4006L4 --: 6A 400V triac in TO-220 isolated package, comparable gate sensitivity and switching behavior, suitable drop-in replacement for low-power AC switching.
  • MAC97A8 --: 0.8A 600V sensitive-gate triac, lower current but usable in light-load circuits where the original 4A rating is over-specified; different series and easy to distinguish.
