Product details
Overview
BTA06-800CRG from STMicroelectronics is a 6A, 800V snubberless triac in insulated TO-220AB package, designed for AC phase control and ON/OFF switching in inductive loads. It features 35mA max gate trigger current (Q1), 200V/µs minimum dV/dt at 125°C, and 2500VRMS voltage-isolated tab compliant with UL E81734. Used in motor speed controllers and heating regulation circuits.
For engineers reviewing the BTA06-800CRG datasheet, BTA06-800CRG pinout, BTA06-800CRG application, or BTA06-800CRG equivalent, key selection criteria include commutation robustness on inductive loads, insulated tab safety rating, gate sensitivity class (C = 25mA standard), and snubberless operation enabling simplified PCB layout without external RC networks.
Technical Context
This triac operates in three quadrants (I, II, III) with logic-compatible gate drive and high commutation performance. Its snubberless architecture eliminates need for external snubbers when switching inductive loads like AC motors or solenoids, supported by 200V/µs dV/dt immunity and 2.7A/ms critical rate of decrease of main current at 125°C.
Thermal design leverages 2.7°C/W junction-to-case resistance in insulated TO-220AB package, enabling 6A RMS conduction at 105°C case temperature. The internal ceramic pad ensures 2500VRMS isolation between tab and die, meeting UL safety requirements for mains-connected equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 6 A - Sustained AC load current handling capability at Tc = 105°C |
| VDRM / VRRM | 800 V - Peak repetitive off-state blocking voltage in both directions |
| IGT (Q1) | 35 mA max - Gate trigger current threshold for quadrant I turn-on, defining driver strength requirement |
| dV/dt (min) | 200 V/µs - Minimum rate of voltage rise before false triggering, critical for inductive load noise immunity |
| Rth(j-c) | 2.7 °C/W - Thermal resistance from junction to case, governing heatsink sizing for 6A operation |
| VTM (max) | 1.55 V - Maximum on-state voltage drop at 8.5A pulse, directly impacting conduction loss and thermal design |
| ITSM (50Hz) | 60 A - Non-repetitive surge current rating for 20ms half-cycle, defining short-circuit withstand capability |
Pinout & Package
Package: TO-220AB insulated (voltage-isolated tab rated 2500VRMS per UL E81734). Tab is electrically isolated from A1/A2 terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main terminal 1 | Reference electrode for gate trigger; connected to load return path in most AC switch configurations |
| A2 (MT2) | Main terminal 2 | High-side AC line connection; polarity relative to A1 defines conduction quadrant |
| G | Gate | Control input for triggering; requires ≥35mA pulse in Q1 for reliable turn-on per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless operation | Enables direct switching of inductive loads (e.g., AC motors) without external RC snubber network, reducing BOM count and board space |
| Insulated tab | 2500VRMS isolation between metal tab and semiconductor die, allowing safe mounting to grounded heatsinks in mains-connected systems |
| Three-quadrant triggering | Supports gate triggering only in quadrants I, II, and III - improves noise immunity and reduces false turn-on vs. 4Q devices in noisy environments |
| ECOPACK® compliance | Lead-free second-level interconnect and RoHS-compliant packaging, meeting global environmental regulations for industrial and consumer products |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA06-800BW | Same 800V/6A rating but 50mA gate trigger current; snubberless architecture retained | Higher gate drive requirement; less suitable for weak-drive microcontrollers or optocouplers with limited output | Select when higher noise immunity is needed and gate driver can supply ≥50mA peak current |
| BTA06-800SW | Logic-level version with 10mA max IGT; same voltage/current ratings and snubberless operation | Enables direct interface with 3.3V/5V logic without buffer transistors; reduced gate power dissipation | Select for low-power MCU-driven designs where gate drive strength is constrained |
Compared with BTA06-800BW, the C-grade offers lower gate drive demand (35mA vs. 50mA); compared with BTA06-800SW, it trades higher gate sensitivity for improved ruggedness against gate overvoltage transients in industrial environments.

FAQ
Is BTA06-800CRG compatible with standard TO-220 heatsinks?
Yes - the insulated TO-220AB package allows direct mounting to grounded heatsinks without electrical isolation pads. The metal tab is rated for 2500VRMS isolation from A1/A2 terminals, satisfying UL E81734 requirements for mains-connected thermal management.
What is the maximum junction temperature for continuous operation?
The absolute maximum operating junction temperature is +125°C. At this temperature, the device supports 6A RMS conduction only if case temperature is maintained at ≤105°C, as specified in Table 3's derating curve and confirmed by Rth(j-c) = 2.7°C/W.
Does BTA06-800CRG require a snubber circuit?
No - its snubberless design eliminates the need for external RC snubbers when switching inductive loads. This is validated by 200V/µs dV/dt immunity and 2.7A/ms critical rate of decrease of main current at 125°C, per Tables 4 and 5.
Can BTA06-800CRG be driven directly by a microcontroller GPIO?
Not reliably - with 35mA max IGT, most 3.3V/5V MCU GPIOs cannot source sufficient peak current. A driver stage (e.g., MOC3021 optocoupler or discrete transistor buffer) is required to ensure consistent triggering across temperature and voltage variations.
