T1235-600G — Snubberless™ Alternistor TRIAC for inductive-load switching
The T1235-600G is a 600 V, 12 A RMS TRIAC from ST's Snubberless™ series, configured as an Alternistor with a single output. It switches AC loads without the external RC snubber normally required for inductive commutation — the device's internal turn-off characteristic handles the dV/dt stress.
Sourcing and lifecycle — active, no LTB watch
No last-time-buy or end-of-life notice is on record. For dual-sourcing or a through-hole alternative, the BTA06-600SRG is a 600 V, 6 A sensitive-gate TRIAC in a through-hole package — same temperature range but lower current rating and different gate sensitivity; verify the load current and gate drive before substituting.
Supplied in Tube, surface-mount D2PAK (TO-263-3) with two leads plus a tab. The tab is the main thermal path and is electrically common with the MT2 terminal — account for this in the PCB layout if multiple devices share a heatsink.
