Product details
Overview
T830-800W from STMicroelectronics is a snubberless 8A RMS, 800V blocking voltage TRIAC in ISOWATT220AB package, designed for high-commutation switching of inductive loads such as drum motor controllers in washing machines. It delivers 5.5 A/ms critical rate of decrease of on-state current (dI/dt)c, 500 V/µs dV/dt immunity at 125°C junction temperature, and operates reliably from –40°C to +125°C.
For engineers reviewing the T830-800W datasheet, T830-800W pinout, T830-800W application, or T830-800W equivalent, key selection criteria include gate trigger sensitivity (30 mA max), thermal resistance (3.1 °C/W junction-to-case), I²t rating (55 A²s), and snubberless operation under high-inductance load commutation.
Technical Context
This TRIAC employs ST's Snubberless™ technology to enable robust turn-off without external snubbers, even with highly inductive loads. Its design integrates optimized silicon structure and gate drive characteristics to sustain 500 V/µs transient voltage reapplied during commutation and maintain latching current ≤70 mA across operating temperature.
The device supports full-cycle AC control with bidirectional conduction, quadrant I/II/III triggering capability, and guaranteed gate trigger current up to 30 mA at 125°C. Its dynamic resistance (40 mΩ) and low on-state voltage (1.4 V at 11 A) minimize conduction losses in motor phase-control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Applications
| Washing Machine Drum Motor Control | Induction Cooktop Power Stage |
|---|---|
Use Scenario: Phase-controlled AC power delivery to universal motor in washing machine spin cycle, requiring frequent direction reversal and high inrush current handling. IC Role / Device Role / Timing Role: Main power switching element in half-wave or full-wave AC controller; triggered synchronously with zero-crossing detection. Use Value: Snubberless architecture eliminates snubber losses and component stress during motor commutation, extending system lifetime and reducing thermal design complexity. | Use Scenario: High-frequency AC power switching for resonant inverter driving induction coil in cooktop surface heating zones. IC Role / Device Role / Timing Role: Bidirectional main switch in series-resonant topology; conducts both half-cycles with precise phase advance control. Use Value: 800 V blocking rating and 500 V/µs dV/dt immunity prevent false triggering during rapid resonant voltage reversals and EMI-rich kitchen environments. |
| Commercial HVAC Fan Speed Controller | Power Tool Motor Starter |
Use Scenario: Variable-speed control of shaded-pole or PSC fan motors in rooftop HVAC units exposed to ambient temperatures up to 70°C. IC Role / Device Role / Timing Role: Line-voltage TRIAC in leading-edge dimming configuration; modulates RMS voltage applied to motor windings. Use Value: Junction-to-case thermal resistance of 3.1 °C/W enables direct heatsink mounting in space-constrained duct-mounted enclosures without forced airflow. | Use Scenario: Soft-start and speed regulation for brushed universal motors in corded drills and sanders subjected to mechanical shock and thermal cycling. IC Role / Device Role / Timing Role: Primary AC switch in motor armature circuit; triggered with controlled phase delay to limit inrush current and torque surge. Use Value: 105 A non-repetitive surge rating (60 Hz, 16.7 ms) withstands repeated motor stall events during bit binding or material jamming. |
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 |
|---|---|---|---|
| BTB16-800CW | 16 A RMS rating, same 800 V VDRM, but higher IGT (50 mA max) and larger TO-220AB package | Suitable for higher-current motor loads; requires stronger gate drive and larger heatsink | Select when >8 A continuous current or higher surge margin is required; not drop-in due to higher gate drive demand |
| MAC12A8G | 12 A RMS, 800 V, but standard (non-snubberless) construction and lower dV/dt (200 V/µs) | Requires external snubber network for inductive loads; less robust in high-dI/dt environments | Choose only for resistive or lightly inductive loads where cost is prioritized over reliability and board space |
Compared with BTB16-800CW and MAC12A8G, T830-800W uniquely balances 8 A capacity, snubberless operation, and 30 mA gate sensitivity-making it optimal for space- and thermal-constrained appliance motor controls where gate drive simplicity and commutation immunity are critical.

FAQ
What is the maximum allowable case temperature for continuous operation?
The T830-800W supports continuous RMS on-state current of 8 A at case temperature (Tc) = 100°C, as specified in the absolute ratings table. Operation above this temperature reduces allowable current per Fig. 2 in the datasheet, with derating to zero at Tc = 125°C. Heatsink design must maintain Tc ≤100°C under worst-case load and ambient conditions.
Does T830-800W require a heat sink in typical appliance applications?
Yes - the ISOWATT220AB package has Rth(j-c) = 3.1 °C/W, and power dissipation at 8 A RMS exceeds 2 W. Without a heatsink, junction temperature would exceed 125°C even at moderate ambient. A minimum 10 cm² aluminum heatsink (with thermal interface) is recommended for sustained 8 A operation in enclosed environments.
Can T830-800W be used in zero-crossing switched applications?
No - T830-800W is not optimized for zero-crossing operation. Its design targets phase-control (leading-edge) triggering where precise gate timing relative to AC phase angle is required. For zero-crossing applications, dedicated zero-crossing TRIACs (e.g., Z0109MN) with integrated optocouplers are recommended instead.
What is the minimum gate trigger pulse width required for reliable turn-on?
A minimum gate pulse width of 10 µs is required to ensure reliable turn-on across temperature and load conditions. The datasheet specifies IGM = 4 A peak gate current for tp = 20 µs; shorter pulses risk incomplete triggering, especially at low junction temperatures or high load inductance.
