The 35 mA maximum hold current (Ih) means the triac will reliably latch on once triggered and will commutate off cleanly when the load current drops below that threshold near the AC zero-crossing. These trigger levels are standard for the 16 A triac class and compatible with common driver ICs like the MOC3063 or discrete transistor drive stages. ## Surge current and thermal capability The BTA16-700CWRG is rated for a non-repetitive surge current (Itsm) of 160 A at 50 Hz and 168 A at 60 Hz. This surge rating covers inrush from incandescent lamp loads, motor start-up, and capacitor charging — common events in AC mains switching. There is no official ST replacement listed for this specific order code; a pin-compatible replacement within the BTA16 family would need to be qualified against the same 700 V / 16 A ratings and Snubberless Alternistor characteristics.","metaTitle":"ST BTA16-700CWRG Triac, 700 V, 16 A, TO-220, Snubberless","metaDescription":"ST BTA16-700CWRG Snubberless Alternistor triac, 700 V off-state, 16 A RMS on-state, TO-220-3, -40 to 125°C.
