Product details
Overview
BTB08-600CRG from STMicroelectronics is a snubberless, standard-sensitivity 8 A, 600 V triac in TO-220AB package, designed for AC mains switching in phase-control and ON/OFF applications. It delivers 8 A RMS on-state current at Tc = 110 °C, supports 600 V repetitive peak off-state voltage (VDRM/VRRM), and requires ≤50 mA gate trigger current (IGT) - enabling direct drive from discrete transistors or logic-level buffers in motor speed controllers and heating regulators.
For engineers reviewing the BTB08-600CRG datasheet, BTB08-600CRG pinout, BTB08-600CRG application, or BTB08-600CRG equivalent, key selection criteria include commutation robustness on inductive loads, gate sensitivity matching to driver capability, thermal resistance (Rth(j–c) = 1.6 °C/W), and TO-220AB mechanical mounting compatibility with heatsink interfaces.
Technical Context
This triac operates in all four quadrants but is optimized as a snubberless device for inductive load commutation, with guaranteed dV/dt immunity of ≥200 V/µs (Tj = 125 °C, gate open) and critical commutation current rate (dl/dt)c ≥5 A/ms under specified dV/dt conditions. Its internal structure eliminates need for external snubber networks in motor starting and relay replacement circuits.
It features a low on-state voltage drop (VTM ≤1.55 V at 11 A, 25 °C; VTO ≤0.85 V at 125 °C) and dynamic resistance (RD ≤50 mΩ), minimizing conduction losses. Thermal performance is defined by junction-to-case resistance of 1.6 °C/W, supporting high-power density designs when mounted on heatsinks per TO-220AB torque spec (0.55 N·m recommended).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 8 A RMS on-state current at Tc = 110 °C - defines continuous AC load handling capacity with standard heatsinking |
| VDRM / VRRM | 600 V repetitive peak off-state voltage - ensures safe blocking of 230 VAC mains with 2× safety margin |
| IGT (max) | 50 mA maximum gate trigger current - compatible with medium-drive BJTs or logic buffers without amplification |
| dV/dt (min) | 200 V/µs minimum critical rate of rise of off-state voltage - enables reliable operation on inductive loads without snubber |
| Rth(j–c) | 1.6 °C/W junction-to-case thermal resistance - determines required heatsink size for thermal management |
| VTM | ≤1.55 V on-state voltage at 11 A, 25 °C - sets conduction loss budget (Pcond ≈ 17 W max at full load) |
| ITSM | 80 A non-repetitive surge current (50 Hz, 20 ms) - withstands motor inrush or short-circuit transients |
Pinout & Package
BTB08-600CRG uses the TO-220AB package: insulated plastic body with three leads, metal tab electrically connected to MT2 (A2), rated for 2500 VRMS isolation. Mounting requires M3 screw and 0.55 N·m torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate triggering; current enters here during quadrant I/III conduction |
| A2 (MT2) | Main Terminal 2 | Electrically tied to insulated metal tab; serves as return path and heatsink interface |
| G | Gate | Controls turn-on; triggers conduction when IGT ≥50 mA applied between G and A1 |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless commutation | Guaranteed dV/dt ≥200 V/µs and (dl/dt)c ≥5 A/ms - eliminates external RC snubbers in motor control |
| Standard gate sensitivity | IGT ≤50 mA - interfaces directly with BC847, ULN2003, or microcontroller GPIO via series resistor |
| High surge rating | ITSM = 80 A (50 Hz, 20 ms) - sustains induction motor startup surges without failure |
| Low on-state loss | VTM ≤1.55 V and RD ≤50 mΩ - reduces thermal stress and improves efficiency in 230 VAC systems |
| UL-certified insulation | 2500 VRMS isolated tab (file E81734) - meets safety requirements for Class I appliances and industrial controls |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTB08-600BWRG | Snubberless version with 50 mA IGT - identical voltage/current ratings but enhanced commutation (dV/dt ≥400 V/µs) | Better suited for highly inductive loads (e.g., solenoid valves, transformer primaries) where higher dV/dt immunity is critical | Select BW if operating near motor stall conditions or with long cable runs inducing voltage transients |
| T835-600B | DPAK-packaged 8 A, 600 V triac with 35 mA IGT; Rth(j–c) = 2.5 °C/W; no insulated tab | Surface-mount alternative requiring PCB copper area for thermal management instead of mechanical heatsink | Choose T835-600B for space-constrained, automated assembly designs where TO-220AB mounting is impractical |
Compared with BTB08-600CRG, BTB08-600BWRG offers superior inductive load immunity at same package and drive level, while T835-600B trades mechanical heatsinking for SMT manufacturability and reduced board footprint - both require re-evaluation of gate drive strength and thermal layout.

FAQ
What is the maximum junction temperature for BTB08-600CRG?
The BTB08-600CRG has an operating junction temperature range of –40 °C to +125 °C. This limit is defined by silicon reliability and packaging integrity; sustained operation above 125 °C risks accelerated parameter drift and premature failure. Thermal design must ensure Tj stays within this window under worst-case ambient and load conditions.
Can BTB08-600CRG be used with microcontroller GPIO without a driver transistor?
No - BTB08-600CRG requires up to 50 mA gate current (IGT), exceeding typical GPIO sink/source capability (≤20 mA). A discrete BJT (e.g., BC847) or dedicated triac driver (e.g., MOC3021 + BTA16) is required to provide sufficient gate charge. Direct GPIO connection risks incomplete turn-on and localized overheating.
Is the metal tab of BTB08-600CRG electrically isolated?
Yes - BTB08-600CRG uses the TO-220AB Insulated package variant, where the metal tab is electrically isolated from the internal die and rated for 2500 VRMS isolation (UL file E81734). This allows safe mounting to grounded heatsinks without additional insulation hardware.
How does BTB08-600CRG differ from the BTA08-600CRG variant?
BTB08-600CRG uses a non-insulated TO-220AB package (tab connected to MT2), while BTA08-600CRG uses the insulated TO-220AB variant (tab isolated, 2500 VRMS). Both share identical electrical specs (8 A, 600 V, 50 mA IGT), but BTA08-600CRG is mandatory for safety-isolated applications; BTB08-600CRG suits cost-sensitive, non-isolated designs with floating heatsinks.
