Product details
Overview
T1035-6G-TR from STMicroelectronics is a 10 A, 600 V Snubberless™ triac in D²PAK package, designed for high-reliability AC mains switching in inductive loads. It delivers 3-quadrant operation, 35 mA max gate trigger current (IGT), 500 V/µs minimum dV/dt at 125 °C, and insulated thermal performance with Rth(j-c) = 1.5 °C/W - used in motor speed controllers and static relays.
For engineers reviewing the T1035-6G-TR datasheet, T1035-6G-TR pinout, T1035-6G-TR application, or T1035-6G-TR equivalent, this page provides verified triac parameters including commutation capability, insulated tab rating (2500 VRMS), junction-to-case thermal resistance, and Snubberless™ 3Q operational validation - critical for inductive load phase control design.
Technical Context
This triac implements a 3-quadrant (3Q) Snubberless™ architecture optimized to sustain high commutation stress without external snubbers. Its gate-trigger characteristics (IGT ≤ 35 mA, VGT ≤ 1.3 V) and latching/holding behavior (IL ≤ 50 mA, IH ≤ 35 mA) are specified across -40 to +125 °C junction temperature range.
It features a ceramic-insulated tab rated at 2500 VRMS per UL1557 (file E81734), enabling safe mounting on heatsinks without isolation hardware. The D²PAK package supports surface-mount assembly while maintaining low Rth(j-c) = 1.5 °C/W and high surge robustness (ITSM = 100 A, tp = 20 ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 10 A RMS - supports continuous AC load switching up to 1.2 kW @ 120 VAC or 2.4 kW @ 240 VAC with proper heatsinking. |
| VDRM / VRRM | 600 V - blocks peak line voltages up to 848 V (120 VAC × √2 × 1.414) with 40 % safety margin for 120 V systems. |
| IGT (max) | 35 mA - enables direct drive from microcontroller GPIO or low-power optocouplers without amplification. |
| dV/dt (min) | 500 V/µs @ Tj = 125 °C - prevents false triggering during fast voltage transients in inductive circuits like motor windings. |
| (dI/dt)c (min) | 5.5 A/ms - sustains rapid current rise during turn-on into highly inductive loads without commutation failure. |
| Rth(j-c) | 1.5 °C/W - allows efficient heat transfer to heatsink; enables 10 A operation at Tc ≤ 95 °C without derating. |
| Insulation Rating | 2500 VRMS - certified per UL1557 (E81734); permits direct heatsink mounting without insulating washers. |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated tab: 3-pin configuration, molded epoxy body, copper leadframe, and internal ceramic insulation between tab and die. Tab is electrically connected to MT2 (A2) and serves as primary thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 (A1) | Main Terminal 1 | Anode 1 - connects to load return side; referenced polarity for gate triggering in quadrants I, II, III. |
| MT2 (A2) | Main Terminal 2 | Anode 2 - connects to AC line or load hot side; electrically tied to insulated metal tab for thermal conduction. |
| G | Gate | Control input - triggers conduction when ≥ 35 mA pulse applied with appropriate polarity relative to MT1. |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ 3Q Operation | Eliminates need for RC snubber networks in inductive loads - reduces BOM count and PCB area in motor controls. |
| UL1557 Insulated Tab | 2500 VRMS isolation enables direct heatsink mounting - simplifies mechanical design and improves thermal reliability. |
| Low IGT (≤35 mA) | Compatible with logic-level drivers (e.g., MOC302x, VO1263) - avoids gate driver ICs in cost-sensitive designs. |
| High dV/dt Immunity | 500 V/µs minimum at 125 °C - ensures stable operation under noisy AC line conditions and transformer leakage spikes. |
| RoHS & ECOPACK® Compliant | Meets EU Directive 2002/95/EC and ST's environmental packaging standards - supports green manufacturing requirements. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA10-600CW | TO-220AB insulated package; same 10 A/600 V/35 mA specs but through-hole mount; Rth(j-c) = 2.4 °C/W. | Preferred where manual assembly, serviceability, or legacy footprint compatibility is required. | Select for prototyping, low-volume production, or designs requiring field-replaceable components. |
| T1050-8G-TR | Same D²PAK package; higher 50 mA IGT, 800 V VDRM, and 9 A/ms (dI/dt)c - optimized for 240 VAC global mains and heavier inductive loads. | Better suited for universal-input appliances and industrial equipment operating at 230–240 VAC with high L/R ratios. | Choose when designing for 240 VAC regions or upgrading surge immunity beyond 600 V blocking. |
Compared with BTA10-600CW, T1035-6G-TR offers superior thermal performance (1.5 vs. 2.4 °C/W) and SMT scalability; versus T1050-8G-TR, it trades higher voltage/surge rating for lower gate drive demand and tighter dV/dt control in 120 VAC systems.

FAQ
What is the maximum junction temperature for continuous operation?
The T1035-6G-TR has an operating junction temperature range of –40 °C to +125 °C. Continuous operation at 125 °C requires strict adherence to derating curves: IT(RMS) must be limited to ≤7.5 A at Tc = 95 °C per Figure 3 in DS3165 Rev 9. Thermal design must maintain case temperature below 95 °C under full load.
Is the tab electrically isolated, and what is its voltage rating?
Yes - the D²PAK tab is internally insulated using ceramic and rated for 2500 VRMS isolation per UL1557 (file E81734). It is electrically connected to MT2 (A2), not ground or floating, and must be mounted on a grounded or appropriately insulated heatsink to maintain safety compliance.
Can T1035-6G-TR replace standard 4Q triacs in existing designs?
No - T1035-6G-TR is a 3-quadrant Snubberless™ device and does not conduct in Quadrant IV. It cannot replace 4Q triacs in circuits requiring full four-quadrant triggering (e.g., certain analog dimmers or bidirectional phase control with negative gate pulses). Verify quadrant compatibility before substitution.
What is the recommended PCB footprint and thermal pad layout?
Per Figure 13 in DS3165 Rev 9, use a 16.90 mm × 10.30 mm copper thermal pad with 3.70 mm clearance to adjacent traces. Include ≥5 thermal vias (0.3 mm diameter, 0.6 mm pitch) connecting the pad to inner-layer ground planes. Copper thickness must be ≥35 µm (1 oz/ft²) for optimal Rth(j-a) performance.
