Product details

Logic-level trigger for low-power control

The Z00607MA 1BA2: Rated 0.8 A RMS continuous on-state current and 600 V off-state blocking voltage, it handles small AC loads such as solenoid valves, small fans, indicator lamps, or solid-state relay pre-drivers in 120 VAC or 230 VAC lines. The 5 mA maximum holding current ensures the triac latches on once triggered and does not drop out prematurely on a lightly loaded neutral leg — a common gotcha with logic-level triacs driving low-wattage loads.

Inrush and surge capability for real loads

Non-repetitive surge current is rated 9 A at 50 Hz and 9.5 A at 60 Hz — roughly 11× the continuous RMS rating, which covers the cold-filament inrush of a 60 W incandescent lamp or the charging current of a small capacitive power supply. Housed in the TO-92-3 (TO-226AA) through-hole package, the part fits legacy PCB layouts and breadboard prototypes; the single-triac configuration means one device per TO-92 package, with the gate, MT1, and MT2 pins laid out in the standard pinout for this package family.

ROHS3 compliant, with no restricted substances under the current EU directive — the part ships in a bag, suitable for reel-free low-volume or prototype procurement.

Frequently asked questions

Will Z00607MA 1BA2 drop into a board that was specified around Z0107NA 5AL2 without rewiring?

Both parts share the same TO-92-3 through-hole package and single-triac configuration, so the mechanical fit is the same. However, the Z0107NA series is rated for 800 V off-state and 1 A RMS, while the Z00607MA 1BA2 is 600 V and 0.8 A RMS. If the original design required the higher voltage or current margin, the Z00607MA 1BA2 may not be a direct electrical replacement — verify the load and line voltage before substituting.
