Product details
Overview
T810H-6G-TR from STMicroelectronics is a high-temperature, logic-level sensitive 8 A TRIAC in D2PAK package, rated for 600 V blocking voltage and 150 °C maximum junction temperature. It delivers low gate trigger current (≤10 mA), high dV/dt immunity (75 V/µs at Tj = 150 °C), and optimized thermal resistance (Rth(j–c) = 1.60 °C/W), enabling compact AC load control in space-constrained industrial and appliance systems.
For engineers reviewing the T810H-6G-TR datasheet, T810H-6G-TR pinout, T810H-6G-TR application, or T810H-6G-TR equivalent, key selection criteria include gate sensitivity at elevated temperature, commutation robustness up to 150 °C, RMS current derating versus case temperature, and D2PAK thermal performance under repetitive surge conditions.
Technical Context
The T810H-6G-TR implements a four-quadrant logic-level TRIAC structure with gate triggering specified across I, II, and III quadrants. Its 1.5 V max on-state voltage (VT) at 11.3 A and 55 mΩ dynamic resistance (Rd) at 150 °C support low conduction loss in mains-frequency switching.
It features enhanced turn-off commutation capability at 150 °C junction temperature, validated by (dI/dt)c of 11.4 A/ms at 0.1 V/µs and 3.0 A/ms at 15 V/µs - critical for reliable zero-crossing and phase-control operation in thermally demanding environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A - Sustained AC load current rating at Tc = 135 °C, enabling direct drive of heating elements or motor windings without forced cooling. |
| VDRM / VRRM | 600 V - Peak repetitive off-state voltage, supporting 230 VAC mains with ≥2× safety margin against transients. |
| IGT MAX | 10 mA - Maximum gate trigger current at 25 °C, compatible with microcontroller GPIO without external driver stages. |
| dV/dt (min) | 75 V/µs at Tj = 150 °C - Immunity to false triggering from fast-rising line noise during hot operation. |
| Rth(j–c) | 1.60 °C/W - Junction-to-case thermal resistance, enabling heatsink sizing for ≤12.8 W power dissipation at full 8 A RMS. |
| VT (max) | 1.5 V at ITM = 11.3 A - On-state voltage drop defining conduction loss (≤17 W at 8 A RMS), directly impacting thermal design. |
| (dI/dt)c | 11.4 A/ms at 0.1 V/µs - Critical rate of decrease of main current ensuring reliable commutation in inductive loads at max Tj. |
Pinout & Package
D2PAK (TO-263) surface-mount package with isolated tab, UL94 V0 epoxy, and recommended mounting torque of 0.4–0.6 N·m. Thermal pad electrically connected to A2 terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A2 | Anode 2 (Main Terminal 2) | High-side AC line connection; electrically tied to thermal pad; must be isolated from PCB ground when used in high-side switch topology. |
| A1 | Anode 1 (Main Terminal 1) | Load return path; referenced to gate for triggering; polarity determines quadrant activation behavior. |
| G | Gate | Logic-level control input; triggers conduction in all four quadrants; requires ≤10 mA pulse for reliable turn-on at 25 °C. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 150 °C with fully specified IGT, VGT, IH, IL, and dV/dt - eliminates derating penalties in sealed enclosures. |
| Low gate drive requirement | IGT ≤ 10 mA enables direct interface with 3.3 V or 5 V MCU outputs, reducing BOM count and layout complexity. |
| Enhanced commutation margin | (dI/dt)c ≥ 11.4 A/ms at 0.1 V/µs ensures reliable turn-off in inductive loads (e.g., solenoids, transformers) even at max Tj. |
| Optimized thermal performance | Rth(j–c) = 1.60 °C/W allows >50% smaller heatsink vs. TO-220AB equivalents at same power dissipation. |
| RoHS-compliant packaging | D2PAK meets EU Directive 2002/95/EC; ECOPACK® grade defined per ST environmental compliance documentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TRIAC-based AC load switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTB16-600BW | 16 A rating, TO-220 package, IGT = 15 mA, Rth(j–c) = 1.8 °C/W, Tj max = 125 °C | Higher current headroom but lower max junction temperature; requires larger heatsink for same thermal load | Select when higher surge current (120 A) is required and board space permits TO-220 mounting |
| Z0109MN | 9 A rating, TO-92 package, IGT = 5 mA, Rth(j–a) = 60 °C/W, Tj max = 110 °C | Lower power handling, no thermal pad, limited to <1 A continuous; suitable only for signal-level triggering | Select only for low-power pilot-stage triggering; not a functional replacement for main load switching |
Compared with BTB16-600BW and Z0109MN, the T810H-6G-TR uniquely balances 8 A RMS capacity, D2PAK surface-mount compatibility, 150 °C junction rating, and ≤10 mA gate drive - making it optimal for thermally dense, microcontroller-driven AC control where reliability trumps raw current headroom.

FAQ
What is the maximum allowable case temperature for continuous 8 A RMS operation?
The T810H-6G-TR supports 8 A RMS continuous current at Tc = 135 °C, as confirmed in Table 2 Absolute Maximum Ratings. Operation above this temperature requires derating per Figure 2; at Tc = 150 °C, maximum IT(RMS) drops to approximately 6.2 A due to thermal saturation limits.
Can the T810H-6G-TR be used without a heatsink in free-air convection?
No - at 8 A RMS, power dissipation exceeds 12 W. With Rth(j–a) = 45 °C/W (D2PAK, 1 cm² copper), junction temperature would exceed 150 °C even at 25 °C ambient. A minimum heatsink with Rth(c–a) ≤ 15 °C/W is required for safe continuous operation.
Is the D2PAK thermal pad electrically isolated from the die?
No - the D2PAK thermal pad is internally connected to the A2 terminal, as shown in the device outline diagram (Figure 16) and confirmed in ST's package documentation. Electrical isolation requires insulating thermal interface material and appropriate PCB stack-up design.
Does the 75 V/µs dV/dt rating apply at 150 °C junction temperature?
Yes - Table 3 explicitly specifies dV/dt = 75 V/µs "at Tj = 150 °C" with gate open. This value represents minimum guaranteed immunity under worst-case thermal stress, ensuring robust operation in high-temperature industrial environments without snubber networks.
