Product details
Overview
T630-800W from STMicroelectronics is a snubberless 800 V, 6 A TRIAC in ISOWATT220AB package, designed for phase-controlled AC switching in inductive loads such as rice cookers and motor speed controllers. It delivers 50 A/µs dI/dt, 500 V/µs dV/dt, and 84 A non-repetitive surge current at 60 Hz, with gate trigger current ≤30 mA.
For engineers reviewing the T630-800W datasheet, T630-800W pinout, T630-800W application, or T630-800W equivalent, key selection criteria include commutation robustness on inductive loads, gate sensitivity (≤30 mA), thermal resistance (Rth(j-c) = 3.4 °C/W), and UL certification (E81734) for safety-critical appliances.
Technical Context
This TRIAC uses ST's Snubberless™ technology to enable reliable turn-off under high dV/dt and high dI/dt conditions without external snubbers. Its quadrants I, II, and III operation supports full-wave AC control with gate-triggered conduction independent of main terminal polarity.
It features a low dynamic on-state resistance (≤50 mΩ at Tj = 125°C) and threshold voltage (≤0.85 V), enabling low conduction losses in thermally constrained applications. The device is rated for continuous operation up to Tj = 125°C and storage up to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM/VRRM | 800 V - Maximum repetitive peak off-state voltage; ensures safe blocking in 230 V AC mains with margin for transients |
| IT(RMS) | 6 A - RMS on-state current at Tc = 105°C; defines continuous power-handling capability with heatsink |
| IGT | ≤30 mA - Max gate trigger current; enables direct drive from microcontrollers or optocouplers without amplification |
| dV/dt (min) | 500 V/µs - Critical rate of rise of off-state voltage; prevents false triggering in noisy inductive environments |
| Rth(j-c) | 3.4 °C/W - Junction-to-case thermal resistance; determines minimum heatsink requirement for 6 A RMS operation |
| ITSM (60 Hz) | 84 A - Non-repetitive surge current for 16.7 ms; supports motor startup and short-duration overload events |
| VTM | ≤1.4 V - On-state voltage at 8.5 A pulse; sets conduction loss and self-heating during conduction |
Pinout & Package
Package: ISOWATT220AB - Insulated plastic power package with metal tab for heatsinking, screw-mountable, Rth(j-c) = 3.4 °C/W, torque limit 0.70 m·N.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; connected to load return or neutral side in AC circuits |
| A2 (MT2) | Main Terminal 2 | High-side AC line connection; carries full load current and defines voltage reference for dV/dt immunity |
| G | Gate | Control input for triggering conduction in all four quadrants; requires ≤30 mA pulse for reliable turn-on |

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 |
|---|---|---|---|
| BTB16-800CW | 16 A rating, TO-220AB package, IGT ≤50 mA, Rth(j-c) = 1.5 °C/W | Higher current capacity but larger footprint and higher gate drive demand | Select when >6 A RMS load current or lower thermal resistance is required |
| MAC12A8G | 12 A rating, TO-220 package, IGT ≤35 mA, no UL listing, Rth(j-c) = 2.0 °C/W | Lacks UL certification; suitable only for non-safety-certified industrial controls | Select only for cost-sensitive, non-certified designs where 800 V blocking and 12 A surge are needed |
Compared with BTB16-800CW and MAC12A8G, T630-800W offers optimal balance of UL compliance, 30 mA gate sensitivity, and ISOWATT220AB mechanical compatibility-making it preferred for certified consumer appliance designs where board space and gate drive simplicity are constraints.

FAQ
What is the maximum case temperature for continuous 6 A RMS operation?
The datasheet specifies IT(RMS) = 6 A at Tc = 105°C. Operation above this case temperature reduces allowable RMS current per Fig. 2. Derating is linear: at Tc = 125°C, max IT(RMS) drops to ~4.3 A. Heatsink design must maintain case temperature ≤105°C under worst-case ambient and airflow conditions.
Can T630-800W replace T620-800W in existing designs?
Yes, with verification of gate drive capability. T630-800W has higher IGT (≤30 mA vs. ≤20 mA), so legacy circuits designed for T620-800W may require increased gate current to ensure reliable triggering across temperature and aging. No changes to pinout, package, or voltage/current ratings are needed.
Does T630-800W support quadrant IV operation?
No. Per datasheet electrical characteristics and symbol, T630-800W is characterized and guaranteed for quadrants I, II, and III only. Quadrant IV (A1 positive, G negative) is not supported and may result in unreliable or non-functional triggering behavior.
What is the recommended gate resistor value for microcontroller-driven operation?
With a 5 V MCU GPIO driving a 30 mA max IGT, a 150 Ω series resistor limits peak gate current to ~33 mA while providing noise immunity. For 3.3 V GPIO, use 100 Ω. Always verify pulse width ≥10 µs and ensure gate drive is referenced to A1 (MT1), not ground, in floating-load configurations.
