The D2PAK (TO-263-3) footprint is the same as a standard D²Pak with two leads plus the tab. The tab is the main terminal (MT2) and carries the full load current. The surface-mount package suits reflow soldering; the Tape & Reel (TR) variant is the ordering code for automated assembly. The Cut Tape (CT) option is available for prototype or low-volume builds. The Snubberless™ series is an established ST product line with multiple current ratings sharing the same TO-263 footprint, so if a future design needs a higher current, the T2535-600G-TR (25 A) or T3035H-6G-TR (30 A) are pin-compatible surface-mount alternatives within the same series — both also Snubberless™ alternistors in D2PAK.","metaTitle":"STMicroelectronics T1235-600G-TR Snubberless™ Triac","metaDescription":"ST T1235-600G-TR Snubberless™ Alternistor triac, 600V off-state, 12A RMS, D2PAK surface mount.

For a through-hole alternative, the T1235H-6I (12 A, TO-220) shares the same 600 V off-state and Snubberless™ construction."},{"question":"What is a snubberless triac?","answer":"A Snubberless™ triac is designed to switch inductive loads without an external RC snubber network. It achieves this through a higher dV/dt immunity and a more robust turn-off characteristic than a standard triac, reducing component count and board area."},{"question":"What is the difference between alternistor and standard triac?","answer":"An alternistor triac has a different internal structure that provides higher dV/dt immunity and better commutating dI/dt capability than a standard triac. This makes it more suitable for inductive loads and reduces the risk of false triggering from line transients."},{"question":"What is the pinout of T1235-600G-TR?","answer":"The D2PAK (TO-263-3) pinout is standard: pin 1 is Main Terminal 1 (MT1), pin 2 is Gate (G), and the tab is Main Terminal 2 (MT2). The tab is electrically active and must be isolated or connected to the load line as per the circuit design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/T1235-600G-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/T1235-600G-TR when reusing this data.
