Product details
Overview
T1610H-6T from STMicroelectronics is a 16 A, 600 V repetitive peak off-state voltage logic-level triac in TO-220AB package, rated for 150 °C maximum junction temperature and 10 mA gate trigger current. It enables direct microcontroller drive for resistive load switching in heating appliances including water heaters, coffee machines, and hand dryers.
For engineers reviewing the T1610H-6T datasheet, T1610H-6T pinout, T1610H-6T application, or T1610H-6T equivalent, key selection criteria include IT(RMS) = 16 A, VDRM = 600 V, IGT ≤ 10 mA, Rth(j-c) = 1.0 °C/W, and thermal cycling robustness for high-reliability heater control designs.
Technical Context
This triac operates in all four quadrants (I–III) with guaranteed triggering at ≤10 mA gate current and ≥0.2 V gate-to-drain voltage at 150 °C. Its 168 A non-repetitive surge rating (tp = 16.7 ms) and 100 A/µs dI/dt capability support transient-heavy resistive loads.
The device uses clip-bonded construction to achieve high ITSM and superior thermal cycling performance versus standard wire-bonded triacs. Its 0.80 V threshold voltage and 22 mΩ dynamic resistance at 150 °C ensure low conduction loss under sustained thermal stress.
Key Specifications

|---|---|
| IT(RMS) | 16 A - Sustained RMS on-state current at TC = 133 °C, defining continuous heater power handling capacity |
| VDRM / VRRM | 600 V - Maximum repetitive blocking voltage at TJ = 150 °C, enabling use in 230 VAC mains with safety margin |
| IGT (max) | 10 mA - Maximum gate trigger current at 25 °C, allowing direct drive from MCU GPIO without buffer stage |
| ITSM (tp = 16.7 ms) | 168 A - Non-repetitive surge current rating, supporting inrush current of large heating elements |
| Rth(j-c) | 1.0 °C/W - Junction-to-case thermal resistance, enabling efficient heatsink coupling for thermal management |
| dI/dt (critical) | 100 A/µs - Minimum rate of rise of on-state current before commutation failure, ensuring reliable turn-on under fast-switching conditions |
| VGT (max) | 1.3 V - Maximum gate trigger voltage at 25 °C, confirming compatibility with 3.3 V or 5 V logic systems |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based resistive load control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-600BWRG | Same 16 A/600 V rating but higher IGT (≤50 mA); TO-220 insulated package with different pinout (G-A2-A1) | Requires gate buffer for MCU drive; better suited for legacy designs using opto-triac drivers | Select if existing PCB layout uses BTA-series footprint and gate buffering is already present |
| MAC16A6YG | 16 A/600 V, logic-level (IGT ≤ 15 mA), but lower ITSM (120 A) and Rth(j-c) = 1.5 °C/W | Less robust under repeated surge events; needs larger heatsink for same thermal load | Choose for cost-sensitive, lower-duty-cycle applications where 120 A surge margin suffices |
Compared with BTA16-600BWRG and MAC16A6YG, the T1610H-6T delivers superior thermal cycling life, lower gate drive demand, and higher surge tolerance-making it optimal for high-reliability, high-cycle heater control where long-term field stability is critical.

FAQ
Is T1610H-6T compatible with 3.3 V microcontrollers?
Yes. With a maximum gate trigger voltage (VGT) of 1.3 V at 25 °C and guaranteed triggering at ≤10 mA, the T1610H-6T interfaces directly with 3.3 V GPIO pins without level-shifting or external driver circuitry. Gate current remains within safe limits even at elevated junction temperatures up to 150 °C.
What is the recommended heatsink interface for TO-220AB mounting?
Mount the T1610H-6T using M3 screws with torque between 0.4–0.6 N·m onto an anodized aluminum heatsink. Use thermally conductive insulating pad (e.g., Sil-Pad 1000) or ceramic washer to maintain electrical isolation while achieving ≤1.0 °C/W total thermal resistance from junction to ambient via heatsink.
Does T1610H-6T support phase-angle dimming control?
Yes. The device supports full-quadrant (I–III) triggering and has a typical turn-on time (tgt) of 2 µs, enabling precise phase-angle control synchronized to zero-crossing detection. Its 100 A/µs dI/dt rating ensures stable conduction initiation even with steep current rise rates in inductive-resistive heater loads.
How does T1610H-6T perform under repeated thermal cycling?
Its clip-bonded die construction provides significantly improved thermal cycling endurance versus wire-bonded triacs-validated for >10,000 cycles between -40 °C and 150 °C junction temperature. This makes it ideal for appliances with frequent on/off cycling, such as coffee machines and hand dryers, where bond-wire fatigue would otherwise cause premature failure.
