Product details
Overview
T810-600G-TR from STMicroelectronics is a snubberless, logic-level 8 A, 600 V triac in D²PAK (TO-263) package, designed for AC phase control and ON/OFF switching in inductive loads. It features 10 mA maximum gate trigger current (IGT), 1.55 V max on-state voltage (VTM), and 40 V/µs minimum critical dV/dt at 125 °C - enabling direct microcontroller interface and robust commutation in motor speed controllers and heating regulation circuits.
For engineers reviewing the T810-600G-TR datasheet, T810-600G-TR pinout, T810-600G-TR application, or T810-600G-TR equivalent, key selection criteria include verified snubberless operation on inductive loads, logic-level gate sensitivity (≤10 mA IGT), thermal resistance Rth(j-c) = 1.6 °C/W, and D²PAK surface-mount compatibility with 1000-unit tape-and-reel delivery.
Technical Context
This triac operates in three quadrants (I, II, III) with snubberless commutation capability, supporting reliable turn-off under high inductive load conditions without external snubber networks. Its logic-level gate drive (IGT ≤ 10 mA at 12 V) allows direct interfacing with 3.3 V/5 V microcontrollers and low-power drivers.
It delivers 8 A RMS on-state current at case temperature TC = 110 °C, with 80 A non-repetitive surge rating (50 Hz, 20 ms), and maintains stable latching (IL ≤ 25 mA) and holding (IH ≤ 15 mA) performance across –40 to +125 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A - Sustains full-sine AC load current up to 8 A at TC = 110 °C without heatsink derating beyond spec limits. |
| VDRM / VRRM | 600 V - Blocks 600 V peak off-state voltage in both directions; suitable for 230 VAC mains with safety margin. |
| IGT (max) | 10 mA - Gate triggers reliably with ≤10 mA DC pulse; enables direct drive from MCU GPIO or low-power buffer ICs. |
| VTM (max) | 1.55 V - On-state voltage drop at 11 A pulse; determines conduction loss (P ≈ IT × VTM) and thermal design. |
| dV/dt (min) | 40 V/µs - Minimum rate of rise of off-state voltage before false triggering; ensures noise immunity in noisy industrial environments. |
| Rth(j-c) | 1.6 °C/W - Junction-to-case thermal resistance; defines heatsink requirement for continuous 8 A operation. |
| dl/dt (min) | 5.4 A/ms - Minimum critical rate of decrease of on-state current; guarantees safe commutation on inductive loads without snubber. |
Pinout & Package
D²PAK (TO-263) surface-mount package with isolated copper tab rated for 2500 VRMS insulation (UL E81734); thermally optimized for PCB copper area ≥1 cm² under tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Main terminal 1 (anode 1) | Reference terminal for gate trigger polarity; connects to load return or neutral side in AC switching. |
| A2 | Main terminal 2 (anode 2) | High-side AC line connection; carries full load current and defines voltage reference for gate drive. |
| G | Gate | Logic-level control input; triggers conduction when pulsed positive relative to A1 (QI) or negative relative to A2 (QIII). |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless commutation | Validated for inductive loads without external RC snubbers; reduces BOM count and board space in motor controls. |
| Logic-level gate drive | IGT ≤ 10 mA at 12 V - eliminates need for gate driver transistors in MCU-based dimmers and smart relays. |
| High dV/dt immunity | 40 V/µs min at 125 °C - prevents false triggering from EMI in industrial AC power systems. |
| Isolated tab (UL certified) | 2500 VRMS isolation between tab and terminals - enables safe mounting on grounded heatsinks in Class I equipment. |
| ECOPACK2 compliance | Halogen-free molding compound, lead-free plating - meets RoHS and environmental requirements for global deployment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA08-600SW | TO-220AB insulated package; same 8 A/600 V rating but higher IGT (10 mA vs. T810's 10 mA - identical), Rth(j-c) = 2.5 °C/W. | Requires mechanical mounting and screw-tightening (0.55 N·m torque); better suited for through-hole prototyping or legacy board designs. | Select when board layout mandates through-hole mounting or when higher creepage/clearance is required via insulated tab. |
| T835-600G | D²PAK package like T810-600G-TR but rated for 35 mA IGT (snubberless, not logic-level); 35 A surge rating vs. 80 A. | Designed for higher-noise, lower-control-fidelity applications (e.g., basic fan control); less suitable for direct MCU drive. | Choose only if gate drive circuit already includes discrete transistor buffering and inductive load stress exceeds T810's 5.4 A/ms dl/dt margin. |
Compared with BTA08-600SW, T810-600G-TR offers superior thermal performance (1.6 vs. 2.5 °C/W) and surface-mount scalability; versus T835-600G, it provides tighter gate sensitivity (10 mA vs. 35 mA) and higher surge robustness (80 A vs. 35 A), making it optimal for compact, logic-driven AC control.

FAQ
What is the maximum junction temperature for continuous operation?
The T810-600G-TR has an operating junction temperature range of –40 to +125 °C. Continuous operation at 125 °C requires maintaining case temperature ≤110 °C per absolute maximum ratings, achievable with adequate PCB copper area (≥1 cm² under tab) and ambient thermal management.
Does this triac require a heat sink in 8 A applications?
Yes - at 8 A RMS, power dissipation reaches ~12.4 W (based on VTM = 1.55 V). With Rth(j-c) = 1.6 °C/W, junction-to-case rise is ~19.8 °C; adding even modest Rth(c-a) (e.g., 20 °C/W) pushes junction temperature beyond 125 °C. A low-thermal-resistance heatsink or large copper pour is mandatory.
Can T810-600G-TR replace BTA08-600B in existing TO-220AB designs?
No - T810-600G-TR uses D²PAK (TO-263) packaging and cannot be mechanically or thermally substituted into TO-220AB footprints. While electrical specs align closely, PCB layout, thermal pad design, and reflow profile differ significantly; redesign is required for migration.
Is the gate trigger polarity sensitive in all quadrants?
Yes - the T810-600G-TR is a 3-quadrant triac (QI, QII, QIII) and does not trigger in quadrant IV. Gate must be positive relative to A1 (QI) or negative relative to A2 (QIII) for reliable turn-on; QII operation requires negative gate relative to A1, but is less robust and not recommended for new designs.
