Product details
Overview
T2035H-6G from STMicroelectronics is a 20 A, 600 V snubberless triac in D²PAK surface-mount package, designed for high-power AC switching in universal motor control circuits. It features 35 mA maximum gate trigger current (IGT), 1000 V/µs minimum dV/dt at 150 °C, and 1.0 °C/W junction-to-case thermal resistance - enabling compact, thermally efficient designs in vacuum cleaner and washing machine drum motor drives.
For engineers reviewing the T2035H-6G datasheet, T2035H-6G pinout, T2035H-6G application, or T2035H-6G equivalent, key selection criteria include its 150 °C junction-rated commutation capability, insulated gate drive compatibility, low on-state voltage (1.5 V max at 28 A), and RoHS-compliant D²PAK footprint optimized for automated SMT assembly.
Technical Context
This triac operates across all four quadrants with enhanced third-quadrant commutation robustness, supporting phase-angle and zero-crossing control topologies in mains-powered motor loads. Its internal ceramic insulation provides 2500 VRMS isolation between MT1/MT2 and heatsink, eliminating need for insulating washers in TO-220AB-insulated variants - though the D²PAK variant relies on PCB copper area for thermal management.
The device uses clip-bonding construction to achieve low thermal resistance and high I²t surge rating (265 A²s). Its snubberless architecture eliminates external RC networks by sustaining ≥1000 V/µs dV/dt and ≥27 A/ms critical rate of current decrease (dl/dt)c at 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 20 A RMS on-state current - supports continuous 2.4 kW resistive load at 120 VAC with proper heatsinking |
| VDRM/VRRM | 600 V repetitive peak off-state voltage - rated for 230 VAC mains with 2.6× safety margin |
| IGT | 35 mA max gate trigger current - compatible with standard microcontroller GPIO or optocoupler drivers |
| dV/dt (Tj = 150 °C) | 1000 V/µs min - enables reliable operation without snubber in high-noise motor drive environments |
| Rth(j-c) | 1.0 °C/W junction-to-case - allows direct mounting to PCB copper pour or small heatsink for thermal management |
| VT (28 A) | 1.5 V max on-state voltage - limits conduction loss to ≤42 W at full RMS current |
| IDRM @ 150 °C | 6.2 mA max leakage at 600 V blocking - ensures stable turn-off under hot, high-voltage conditions |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated tab: thermally conductive but electrically insulated metal pad bonded to MT2 terminal; requires no external insulator when mounted to grounded heatsink via soldered copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Main Terminal 1 | Anode-side main current path; referenced as common return in most phase-control circuits |
| MT2 | Main Terminal 2 | Cathode-side main current path; connected to heatsink via isolated metal tab in D²PAK |
| G | Gate | Trigger input; low-current (≤35 mA) pulse initiates conduction in any quadrant |
Key Features

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 |
|---|---|---|---|
| T2035H-6T | Same electrical specs, but in through-hole TO-220AB (non-insulated) package | Requires mechanical insulator when mounted to grounded heatsink; higher Rth(j-a) than D²PAK | Select for manual assembly or legacy board designs where SMT is unavailable |
| T2050H-6G | 50 mA IGT (vs. 35 mA), otherwise identical ratings and D²PAK package | Suitable for higher-noise environments where gate drive margin must exceed 35 mA | Select when driving from weak gate sources or where long trace inductance increases trigger uncertainty |
Compared with T2035H-6T, the T2035H-6G offers superior thermal performance and automated assembly compatibility; compared with T2050H-6G, it delivers lower gate drive power demand while maintaining identical voltage/current/thermal ratings - making it optimal for microcontroller-driven, space-constrained motor controls.

FAQ
What is the maximum junction temperature rating for T2035H-6G?
The T2035H-6G is rated for continuous operation up to 150 °C junction temperature, with all key parameters - including dV/dt, dl/dt, and IGT - guaranteed at this temperature. This enables reliable use in thermally demanding motor control applications where ambient temperatures exceed 85 °C and heatsinking is limited.
Does T2035H-6G require an external snubber circuit?
No. The T2035H-6G is a snubberless triac, characterized for ≥1000 V/µs dV/dt and ≥27 A/ms (dl/dt)c at 150 °C junction temperature. These specifications eliminate the need for external RC snubbers in typical universal motor and fan control applications, reducing component count and PCB area.
How is thermal management handled in the D²PAK package?
The D²PAK package uses a clip-bonded construction with a thermally conductive but electrically isolated metal tab connected to MT2. Thermal transfer occurs via soldered copper area on the PCB - 1 cm² of 2 oz copper yields ~45 °C/W Rth(j-a); increasing copper area to 10 cm² reduces it to ~20 °C/W per Figure 13 in DS5314.
Is T2035H-6G UL-certified?
Yes. The T2035H-6G carries UL certification under file E81734, verifying its 2500 VRMS isolation rating and compliance with UL 1557 for reinforced insulation. This certification applies to the device itself and supports system-level safety approvals in end equipment.
