Product details
Overview
T2035H-600TRG from STMicroelectronics is a Snubberless™ high-temperature 20 A, 600 V triac in TO-220AB package, designed for phase-controlled switching of inductive and universal motor loads at junction temperatures up to 150 °C. It delivers 35 mA gate trigger current, 1.5 V on-state voltage at 28 A, and 50 A/µs critical dI/dt rating - enabling robust commutation in vacuum cleaners, washing machines, ovens, and electric hobs.
For engineers reviewing the T2035H-600TRG datasheet, T2035H-600TRG pinout, T2035H-600TRG application, or T2035H-600TRG equivalent, key selection criteria include high-temperature operation (Tj ≤ 150 °C), snubberless commutation capability, thermal resistance (Rth(j–c) = 1 °C/W), and gate sensitivity (IGT ≤ 35 mA) in AC mains control circuits.
Technical Context
This triac operates in all four quadrants with guaranteed triggering in QI, QII, and QIII. Its Snubberless™ architecture eliminates external snubber networks by sustaining ≥300 V/µs dV/dt at Tj = 150 °C and supporting ≥8.9 A/ms (dI/dt)c without snubbers.
Thermal design is optimized via low Rth(j–c) = 1 °C/W (TO-220AB), enabling 20 A RMS conduction at Tc = 127 °C. On-state characteristics are defined by VTO = 0.80 V and RD = 21 mΩ at Tj = 150 °C, reducing power loss in high-duty-cycle appliance controls.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 20 A - Sustains full-sine AC load current up to 20 A at case temperature 127 °C without derating. |
| VDRM / VRRM | 600 V - Blocks 600 V peak off-state voltage, suitable for 230 VAC mains with safety margin. |
| IGT (Q1) | 35 mA max - Low gate drive requirement enables direct MCU GPIO or optocoupler interface. |
| Tj MAX | 150 °C - Rated for continuous operation in hot environments like cooktops and ovens. |
| Rth(j–c) | 1 °C/W - Enables compact heatsink design: ~20 W dissipation yields only 20 °C rise above case. |
| dI/dt (critical) | 50 A/µs - Supports fast turn-on into inductive loads without false commutation. |
| VGD (min) | 0.15 V at 150 °C - Ensures noise immunity against gate leakage during high-temperature operation. |
Pinout & Package
TO-220AB package with insulated mounting tab (non-insulated variant used here per ordering code TRG). Standard 3-pin configuration: A1 (MT1), A2 (MT2), G (Gate), with A2 and G on same side, A1 opposite.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; connects to load return or neutral side in phase-control topology. |
| A2 (MT2) | Main Terminal 2 | High-side main current path; ties to AC line input or bridge output in bidirectional switching. |
| G | Gate | Controls conduction onset in all quadrants; requires ≥35 mA pulse for reliable turn-on at Tj = 150 °C. |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Eliminates external RC snubber components by guaranteeing ≥300 V/µs dV/dt immunity and ≥8.9 A/ms (dI/dt)c at 150 °C. |
| High-temperature operation | Rated for continuous 150 °C junction temperature, enabling use in sealed, thermally constrained appliances. |
| Low on-state resistance | RD = 21 mΩ at 150 °C reduces conduction loss to <1.2 W at 20 A RMS, improving system efficiency. |
| Quadrant III robustness | Guaranteed IGT ≤ 35 mA and IL ≤ 50 mA in QIII supports reliable triggering with negative gate pulses in cost-sensitive designs. |
| ECOPACK® compliance | Lead-free second-level interconnect meets RoHS and JEDEC JESD97 marking requirements for environmental compliance. |
Applications
| Vacuum Cleaner Motor Control | Washing Machine Drum Drive |
|---|---|
Use Scenario: Phase-angle dimming of universal motor speed under variable load and dust-clogged airflow conditions. IC Role / Device Role / Timing Role: Bidirectional AC switch controlling RMS voltage applied to motor windings via zero-crossing synchronized gate pulses. Use Value: Snubberless operation prevents false turn-off during high-dI/dt transients caused by brush arcing; 150 °C rating accommodates enclosed motor housing temperatures. | Use Scenario: Speed and direction control of induction motor during spin, wash, and rinse cycles with frequent polarity reversal. IC Role / Device Role / Timing Role: Main AC power switch enabling half-wave or full-wave phase control with precise timing relative to zero-crossing detection. Use Value: High dV/dt immunity (≥300 V/µs) suppresses false triggering from EMI generated by pump and motor commutation noise. |
| Oven Heating Element Control | Electric Hob Surface Control |
Use Scenario: Duty-cycled power delivery to resistive heating elements in convection ovens with ambient cabinet temperatures >100 °C. IC Role / Device Role / Timing Role: High-current AC switch modulating 230 VAC supply to heater coils using burst-fire or phase-control schemes. Use Value: Junction temperature rating of 150 °C allows direct mounting on shared heatsinks with other power stages, eliminating thermal derating penalties. | Use Scenario: Rapid thermal ramp-up and hold control of ceramic glass cooking zones with localized hotspots exceeding 120 °C near device mounting area. IC Role / Device Role / Timing Role: Mains-frequency AC switch delivering pulsed power to coil-based induction heaters or resistive elements. Use Value: Rth(j–c) = 1 °C/W enables stable 20 A operation with minimal heatsink mass, reducing bill-of-materials cost and board space. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC power control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTB20-600CW | Same 20 A/600 V rating but rated only to Tj = 125 °C; higher IGT (50 mA); no Snubberless™ certification. | Limited to lower-ambient appliances (e.g., dishwashers); requires external snubber for inductive loads. | Select when cost is primary constraint and thermal environment stays below 110 °C case temperature. |
| MAC20MG600 | 20 A/600 V, Tj = 125 °C, IGT = 40 mA; TO-220AB package; lacks documented dV/dt immunity >200 V/µs at high Tj. | Suitable for basic resistive heating but not recommended for universal motors with high commutation stress. | Prefer for legacy designs where Snubberless™ behavior is not required and gate drive margin is sufficient. |
Compared with BTB20-600CW and MAC20MG600, the T2035H-600TRG provides verified 150 °C operation, guaranteed snubberless performance, and superior dV/dt immunity - making it the only choice for thermally aggressive, noise-prone motor control in premium appliances.

FAQ
Is T2035H-600TRG compatible with standard TO-220AB heatsinks?
Yes - T2035H-600TRG uses the standard TO-220AB outline (per Table 5) with non-insulated tab, allowing direct mechanical and thermal attachment to industry-standard clip-on or bolt-down heatsinks. Thermal resistance is specified at Rth(j–c) = 1 °C/W under full contact and proper mounting torque.
Does this triac require a heat sink for 20 A RMS operation?
Yes - at 20 A RMS, power dissipation exceeds 15 W (based on VTM ≈ 1.5 V and RD ≈ 21 mΩ). Without a heatsink, junction temperature would exceed 150 °C within seconds. A heatsink maintaining Tc ≤ 127 °C is mandatory per Absolute Maximum Ratings.
Can T2035H-600TRG replace older T2035-600 devices?
No - T2035H-600TRG is not a drop-in replacement for legacy T2035-600. The "H" suffix denotes Snubberless™ architecture, higher dV/dt immunity, and 150 °C rating versus 125 °C for standard versions. Electrical behavior under commutation stress differs significantly.
What is the maximum allowable gate pulse width for reliable triggering?
The datasheet specifies IGM = 4 A peak gate current for tp = 20 µs at Tj = 150 °C. Pulses longer than 20 µs risk exceeding PG(AV) = 1 W average gate power limit. For robust triggering, use 10–15 µs pulses at ≥50 mA to ensure margin across temperature and aging.
