Product details
Overview
T3035H-6G from STMicroelectronics is a 30 A, 600 V Snubberless Triac in D²PAK package, designed for high-noise industrial AC load control with 35 mA gate trigger current, 1000 V/µs dV/dt immunity at 150 °C, and ceramic-insulated 2500 VRMS isolation-used in universal motor drives for power tools and major appliances.
For engineers reviewing the T3035H-6G datasheet, T3035H-6G pinout, T3035H-6G application, or T3035H-6G equivalent, this device delivers verified 150 °C junction operation, low thermal resistance (0.8 °C/W), high 3-quadrant commutation robustness, and RoHS/UL-certified packaging for reliable solid-state AC switching in space-constrained designs.
Technical Context
This H-series triac uses ST's Snubberless architecture to eliminate external snubbers while maintaining ≥1000 V/µs static dV/dt immunity up to Tj = 150 °C and ≥33 A/ms critical rate of decrease of main current without snubber. Its internal ceramic pad ensures 2500 VRMS isolation between MT1/MT2 and heatsink.
Rated for 30 A RMS at Tc = 121 °C, it achieves low on-state voltage (1.55 V max at 42 A, 25 °C) and dynamic resistance (15 mΩ max at 150 °C), enabling heatsink size reduction versus electromechanical relays in continuous-duty appliance motor controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 30 A RMS - supports continuous 30 A AC load current at case temperature ≤121 °C in D²PAK package |
| VDRM/VRRM | 600 V - blocks 600 V peak off-state voltage, suitable for 230 VAC mains with safety margin |
| IGT | 35 mA max - low gate drive requirement compatible with standard microcontroller GPIO or optocoupler outputs |
| dV/dt (Tj = 150 °C) | 1000 V/µs min - high noise immunity prevents false triggering in electrically noisy environments like power tools |
| Rth(j-c) | 0.8 °C/W - enables efficient heat transfer to heatsink, reducing thermal derating in compact enclosures |
| Isolation Voltage | 2500 VRMS - internal ceramic pad provides reinforced insulation for safe mounting on conductive heatsinks |
| Operating Tj | −40 to +150 °C - rated for full performance across extended industrial temperature range without derating |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated tab; thermally optimized for PCB copper area mounting; UL certified (E81734), RoHS compliant, halogen-free molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |

| A1 (MT1) | Main Terminal 1 | Primary current path terminal; connects to load return or neutral side in AC phase-control circuits |
| A2 (MT2) | Main Terminal 2 | Main current path terminal; connects to AC line input; electrically isolated from tab via internal ceramic pad |
| G | Gate | Trigger control input; requires ≥35 mA pulse to initiate conduction in all three quadrants; referenced to A1 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar AC power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST T3050H-6G | Higher IGT (50 mA max) and improved dV/dt (1500 V/µs) but identical package, voltage, and current ratings | Better noise immunity in ultra-high EMI environments (e.g., welding equipment); slightly higher gate drive power required | Select when system-level EMI exceeds 1000 V/µs or gate driver can support 50 mA pulses |
| ON Semiconductor BTB32-600CW | TO-220AB package, 32 A RMS, 600 V, 50 mA IGT, no ceramic isolation (requires external insulator) | Larger footprint and higher Rth(j-c) (1.2 °C/W); needs additional isolation hardware for chassis mounting | Choose only if legacy TO-220AB layout reuse is mandatory and isolation can be added externally |
Compared with T3035H-6G, T3050H-6G offers superior noise immunity at same thermal and electrical specs, while BTB32-600CW trades isolation and thermal efficiency for package compatibility-making T3035H-6G optimal for new SMT designs prioritizing miniaturization and safety-certified integration.

FAQ
What is the maximum allowable case temperature for continuous 30 A RMS operation?
The T3035H-6G supports 30 A RMS continuous current at Tc = 121 °C in D²PAK package, as specified in Table 1 of DS6689 Rev 9. Exceeding this temperature requires linear derating per Figure 2; at Tc = 100 °C, RMS current capability rises to ~35 A.
Does the D²PAK package provide galvanic isolation between terminals and heatsink?
Yes-the T3035H-6G integrates an internal ceramic pad that provides 2500 VRMS isolation between A1/A2 terminals and the metal tab/heatsink interface, eliminating need for external insulating washers in chassis-mounted designs.
Can this triac replace a mechanical relay in a 230 VAC, 15 A resistive load application?
Yes-its 600 V VDRM and 30 A IT(RMS) rating exceed requirements for 230 VAC/15 A loads. With verified 150 °C operation and snubberless design, it delivers longer lifetime, silent operation, and faster switching than electromechanical relays in such applications.
Is tape-and-reel packaging available for automated SMT assembly?
Yes-T3035H-6G-TR is the tape-and-reel variant (1000 units per 13-inch reel), fully compatible with standard pick-and-place equipment. The base part T3035H-6G ships in tube format (50 units) for prototyping or low-volume use.
