Product details
Overview
T1635H-600TRG from STMicroelectronics is a Snubberless™ high-temperature triac rated for 16 A RMS on-state current, 600 V blocking voltage, and 35 mA gate trigger current (Q1), designed for phase-controlled switching of universal motors and inductive loads in hot-appliance applications including ovens, cookers, and electric heaters operating up to 150 °C junction temperature.
For engineers reviewing the T1635H-600TRG datasheet, T1635H-600TRG pinout, T1635H-600TRG application, or T1635H-600TRG equivalent, key selection criteria include commutation robustness at high Tj, snubberless operation, dV/dt immunity ≥300 V/µs at 150 °C, and thermal resistance Rth(j-c) = 2.1 °C/W in TO-220AB insulated package.
Technical Context
This triac employs ST's Snubberless™ architecture to eliminate external snubbers across full operating temperature range (−40 to +150 °C), enabling reliable commutation without RC networks. Its high (dI/dt)c ≥7.1 A/ms and dV/dt ≥300 V/µs at Tj = 150 °C ensure noise-immune turn-off in noisy inductive environments.
Designed for AC mains phase control, it supports quadrant I and III triggering with symmetrical gate characteristics, and features low on-state voltage (VTM ≤1.5 V at 22.5 A, Tj = 25 °C) and low dynamic resistance (RD ≤23 mΩ at Tj = 150 °C), minimizing conduction losses in thermally constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A - Sustains continuous load current in motor and heater control without forced cooling at TC ≤110 °C |
| VDRM/VRRM | 600 V - Blocks standard 230 VAC mains with 2.6× safety margin against transient overvoltage |
| IGT (Q1) | 35 mA - Low gate drive requirement compatible with microcontroller GPIO or optocoupler outputs |
| dV/dt (min) | 300 V/µs at Tj = 150 °C - Prevents false triggering from EMI or inductive kickback in hot environments |
| Rth(j-c) | 2.1 °C/W - Enables compact heatsink design: ~21 W dissipation allowable at ΔT = 44 °C (TC = 110 °C) |
| (dI/dt)c | 7.1 A/ms - Supports snubberless commutation of highly inductive loads like universal motor windings |
| VTM / RD | ≤1.5 V / ≤23 mΩ - Limits conduction loss to <2.4 W at 16 A RMS, reducing thermal stress in sealed enclosures |
Pinout & Package
Supplied in TO-220AB insulated package (2.3 g, creepage ≥5 mm), featuring electrically isolated metal tab for direct heatsink mounting without insulating pads. Pin assignment verified per STMicroelectronics datasheet Rev 1 (Aug 2006).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; connects to load return or neutral side in AC phase control |
| A2 (MT2) | Main Terminal 2 | High-side AC line connection; carries full load current and withstands full VDRM |
| G | Gate | Controls conduction onset; requires ≥35 mA pulse in Q1 or Q3 for reliable turn-on at full temperature range |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ operation | Eliminates external RC snubber components, reducing BOM count and PCB area in appliance motor controls |
| 150 °C junction rating | Enables direct mounting in high-ambient zones (e.g., oven cavity walls) without derating or airflow dependency |
| High commutation immunity | Guaranteed turn-off under inductive load conditions without false re-triggering, even at max Tj |
| Low thermal resistance | Rth(j-c) = 2.1 °C/W allows use of small extruded or stamped heatsinks instead of fan-cooled solutions |
Applications
| Oven Temperature Control | Electric Cooker Power Regulation |
|---|---|
Use Scenario: Precise power delivery to heating elements during bake/broil cycles with variable duty-cycle phase control. IC Role / Device Role / Timing Role: Main AC power switch executing zero-crossing or phase-angle firing under MCU supervision.

IC Role / Device Role / Timing Role: Solid-state replacement for electromechanical relays, enabling silent, wear-free switching. Use Value: 16 A RMS rating supports peak heater loads up to 3.7 kW at 230 VAC; 2.1 °C/W Rth(j-c) permits integration into space-constrained coffee machine baseplates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC phase control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTB16-600CW | Same 16 A/600 V rating but rated only to 125 °C junction; lower dV/dt (200 V/µs at 125 °C); no Snubberless™ certification | Limited to ambient ≤85 °C; requires external snubber in high-noise motor drives | Select when cost sensitivity outweighs thermal margin and snubber elimination needs |
| T1635-600G | Identical electrical specs but in D2PAK (Rth(j-c) = 1.2 °C/W); non-insulated tab; higher thermal performance but requires isolation hardware | Better for PCB-mounted, fan-cooled systems; unsuitable for direct chassis heatsinking | Select when board-level thermal management is preferred and isolation can be implemented externally |
Compared with BTB16-600CW and T1635-600G, the T1635H-600TRG uniquely combines 150 °C operation, certified snubberless behavior, and insulated TO-220AB packaging-enabling simplified, high-reliability designs in sealed, high-temperature appliances where isolation and thermal headroom are critical.

FAQ
What is the maximum case temperature for continuous operation of T1635H-600TRG?
The device is rated for continuous operation with case temperature (TC) up to 110 °C, corresponding to a maximum junction temperature of 150 °C under specified thermal conditions. This limit is defined in Absolute Maximum Ratings Table 1 and validated by thermal resistance Rth(j-c) = 2.1 °C/W. Exceeding TC = 110 °C risks exceeding Tj = 150 °C and violating safe operating area limits.
Does T1635H-600TRG require a heatsink in all applications?
Yes - a heatsink is mandatory for any application drawing ≥2 A RMS continuously. At IT(RMS) = 16 A, power dissipation exceeds 20 W; without heatsinking, junction temperature would rapidly exceed 150 °C. The TO-220AB insulated package allows direct mounting to grounded metal chassis, but thermal interface material and adequate surface area remain essential per Figure 2 and Figure 3 derating curves.
Can T1635H-600TRG replace mechanical relays in coffee machines?
Yes - it is explicitly qualified for this use, offering silent, bounce-free, and wear-free switching of resistive heating elements up to 3.7 kW at 230 VAC. Its 150 °C rating matches coffee machine internal ambient temperatures, and Snubberless™ operation eliminates relay-contact arcing failure modes. Gate drive must be isolated (e.g., MOC3021) and current-limited to ≤4 A peak per datasheet IGM spec.
Is T1635H-600TRG RoHS-compliant and lead-free?
Yes - it is supplied in an ECOPACK® package with lead-free second-level interconnect, compliant with RoHS Directive 2011/65/EU. The "ECOPACK" marking appears on the package and inner box label, and JEDEC JESD97-compliant soldering profiles are documented in the official ST datasheet. No lead content is present in terminations or die attach.
