Product details
Overview
BTA06-800TWRG from STMicroelectronics is a 6A, 800V snubberless logic-level triac in insulated TO-220AB package, designed for AC phase control and switching in inductive loads. It features 5mA gate trigger current (IGT), 2500VRMS voltage-isolated tab, and high commutation robustness (dV/dt ≥ 1000 V/µs, (dI/dt)c ≥ 5.3 A/ms) enabling reliable operation in motor speed controllers and lighting dimmers.
For engineers reviewing the BTA06-800TWRG datasheet, BTA06-800TWRG pinout, BTA06-800TWRG application, or BTA06-800TWRG equivalent, key selection criteria include gate sensitivity (5 mA), insulated package rating (2500 VRMS), snubberless operation on inductive loads, and thermal resistance (Rth(j-c) = 2.7 °C/W).
Technical Context
This triac operates in three quadrants (I, II, III) with logic-level gate drive compatibility, allowing direct interfacing with microcontrollers and low-power drivers without external amplification. Its snubberless architecture eliminates need for RC snubbers in inductive load switching, supported by high critical dV/dt (≥1000 V/µs) and commutation capability (dI/dt ≥ 50 A/µs).
Thermal design is enabled by an internal ceramic pad providing 2500 VRMS isolation between the metal tab and die, meeting UL E81734 requirements. Junction-to-case thermal resistance is 2.7 °C/W, and maximum junction temperature is +125°C under continuous conduction at Tc = 105°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 6 A - Continuous RMS current handling capacity for full-sine-wave AC loads |
| VDRM / VRRM | 800 V - Peak repetitive off-state voltage rating, defining maximum AC line voltage tolerance |
| IGT (Q1) | 5 mA - Maximum gate trigger current required in Quadrant I, enabling direct MCU GPIO drive |
| dV/dt (min) | 1000 V/µs - Minimum rate of rise of off-state voltage before false triggering, critical for inductive noise immunity |
| Rth(j-c) | 2.7 °C/W - Thermal resistance from junction to case, determining heatsink sizing for 105°C case temperature limit |
| VTM (max) | 1.55 V - Maximum on-state voltage drop at 8.5 A, defining conduction loss and power dissipation |
| Isolation Rating | 2500 VRMS - Voltage isolation between MT2/tab and internal die, satisfying UL safety compliance |
Pinout & Package
Package: TO-220AB insulated (metal tab electrically isolated from die, rated 2500 VRMS). Dimensions per STMicroelectronics mechanical drawing: 15.9 × 10.4 × 4.6 mm (L × W × H), weight 2.3 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; current flows between A1 and A2 during conduction |
| A2 (MT2) | Main Terminal 2 | High-side main current path; connected to load or line; tab is internally tied to A2 |
| G | Gate | Control input; triggers conduction when ≥5 mA pulse applied between G and A1 in QI |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless operation | Enables direct switching of inductive loads (e.g., motors, solenoids) without external RC snubber networks |
| Logic-level gate sensitivity | 5 mA IGT allows direct drive from 3.3 V/5 V microcontroller GPIO pins without buffer transistors |
| Voltage-isolated tab | 2500 VRMS insulation between metal tab (A2) and semiconductor die satisfies UL E81734 safety certification |
| High commutation robustness | (dI/dt)c ≥ 5.3 A/ms at (dV/dt)c = 10 V/µs ensures reliable turn-off under fast voltage transients on inductive loads |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTB06-800TWRG | Non-insulated TO-220AB package; tab electrically connected to A2; Rth(j-c) = 1.8 °C/W | Requires insulated mounting hardware to meet safety isolation; better thermal performance for same footprint | Select when heatsink isolation is managed externally and lower thermal resistance is prioritized |
| BTA06-800CWRG | Snubberless version with 35 mA IGT; higher gate drive requirement; same 800 V/6 A rating | Suitable where gate drive strength exceeds 5 mA (e.g., optocoupler outputs); less sensitive to noise-induced false triggering | Select when system uses legacy opto-triac drivers or requires higher noise margin at gate |
Compared with BTB06-800TWRG and BTA06-800CWRG, the BTA06-800TWRG uniquely combines ultra-low gate drive (5 mA), reinforced insulation (2500 VRMS), and snubberless inductive load capability-making it optimal for space-constrained, safety-critical, microcontroller-driven AC control.

FAQ
What is the maximum junction temperature for continuous operation?
The BTA06-800TWRG has a maximum operating junction temperature of +125°C. This rating applies under conditions where case temperature does not exceed +105°C and RMS on-state current remains ≤6 A. Derating is required above 105°C case temperature per Figure 2 in the datasheet.
Can this triac replace a mechanical relay in a 230 VAC, 5 A resistive load?
Yes - the BTA06-800TWRG supports 6 A RMS at 230 VAC, exceeding 5 A requirements. Its 800 V blocking voltage provides ample margin, and the 2500 VRMS insulated tab allows safe mounting to grounded heatsinks, fulfilling key safety and reliability needs of solid-state relay designs.
Does the "TW" suffix indicate full 3-quadrant or 4-quadrant operation?
The "TW" suffix denotes a snubberless logic-level triac operating in three quadrants (I, II, III), as confirmed in Table 5. It does not conduct in Quadrant IV; gate triggering is only specified for QI–QIII, which is standard for optimized snubberless performance on inductive loads.
Is lead-free (RoHS-compliant) packaging available?
Yes - the BTA06-800TWRG is supplied in STMicroelectronics' ECOPACK® package, featuring lead-free second-level interconnects and compliant with JEDEC JESD97. The inner box label and package marking indicate RoHS status per ST's environmental specifications.
