Product details
Overview
BTB06-600BWRG from STMicroelectronics is a 6 A, 600 V snubberless logic-level triac in TO-220AB non-insulated package, designed for AC phase control and switching in inductive loads. It features 5 mA maximum gate trigger current (Q1), 1000 V/µs dV/dt immunity, and operates up to 125°C junction temperature. Used in motor speed controllers and lighting dimmers requiring robust commutation without external snubbers.
For engineers reviewing the BTB06-600BWRG datasheet, BTB06-600BWRG pinout, BTB06-600BWRG application, or BTB06-600BWRG equivalent, key selection criteria include gate sensitivity (5 mA IGT), snubberless operation on inductive loads, TO-220AB thermal resistance (1.8 °C/W), and compliance with UL insulation requirements via internal ceramic pad in insulated variants.
Technical Context
This triac operates in three quadrants (I, II, III) with logic-level gate drive compatibility, enabling direct interface with microcontrollers and low-power drivers. Its high commutation performance-evidenced by 1000 V/µs critical dV/dt and 5.3 A/ms (dI/dt)c at 10 V/µs-is optimized for inductive load turn-off without snubber networks.
The device uses a planar passivated silicon structure with integrated gate protection and exhibits low on-state voltage (1.55 V at 8.5 A) and dynamic resistance (60 mΩ), supporting efficient power handling in 50/60 Hz AC line applications up to 6 A RMS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 6 A - Sustains continuous AC load current without derating at Tc = 110°C |
| VDRM / VRRM | 600 V - Blocks 600 V peak reverse/repetitive off-state voltage reliably |
| IGT (Q1) | 5 mA max - Enables direct drive from 3.3 V/5 V logic outputs without buffer stage |
| dV/dt (min) | 1000 V/µs - Prevents false triggering during fast transients on inductive loads |
| Rth(j-c) | 1.8 °C/W - Allows 6 A operation with modest heatsinking (e.g., 10°C rise at 10.8 W dissipation) |
| VTM | 1.55 V max - Limits conduction loss to ≤9.3 W at 6 A RMS (sinusoidal) |
| (dI/dt)c | 5.3 A/ms at 10 V/µs - Ensures reliable commutation under worst-case inductive turn-off |
Pinout & Package
BTB06-600BWRG uses the TO-220AB non-insulated package with metal tab electrically connected to MT2 (A2). The case serves as a heatsink and must be isolated from other circuit potentials if required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; current enters here in Q1/Q2 conduction |
| A2 (MT2) | Main Terminal 2 | Connected to metal tab; carries full load current and provides thermal path |
| G | Gate | Controls conduction onset; triggers in quadrants I, II, III with ≤5 mA pulse |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless operation | Eliminates need for RC snubber network on inductive loads, reducing BOM count and board space |
| Logic-level gate sensitivity | 5 mA max IGT enables direct MCU GPIO or optocoupler output drive without amplification |
| High commutation robustness | 1000 V/µs dV/dt and 5.3 A/ms (dI/dt)c ensure reliable turn-off with motors and solenoids |
| TO-220AB thermal performance | 1.8 °C/W junction-to-case resistance supports 6 A RMS with minimal heatsink volume |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA06-600BWRG | Insulated TO-220AB package (2500 VRMS isolation); same electrical specs | Required where MT2 isolation from heatsink is mandatory (e.g., floating ground systems) | Select when safety certification demands reinforced insulation between load and heatsink |
| BTB06-600SWRG | 10 mA IGT (vs. 5 mA); otherwise identical snubberless 3Q operation and package | Suitable where gate drive capability exceeds 5 mA but logic-level simplicity still needed | Choose when existing driver can supply ≥10 mA and tighter gate timing margin is acceptable |
Compared with BTA06-600BWRG, BTB06-600BWRG offers lower thermal resistance (1.8 vs. 2.7 °C/W) but requires external MT2 isolation; versus BTB06-600SWRG, it delivers superior noise immunity with half the gate current requirement-critical for weak-drive microcontrollers.

FAQ
What is the maximum junction temperature for BTB06-600BWRG?
The absolute maximum operating junction temperature is +125°C, validated across all electrical parameters in the datasheet. Derating begins above 105°C case temperature per Figure 2, and thermal design must maintain Tj ≤ 125°C under worst-case load and ambient conditions using Rth(j-c) = 1.8 °C/W.
Does BTB06-600BWRG require a heat sink in all applications?
Yes-continuous 6 A RMS operation requires a heatsink. At 10.8 W conduction loss (6 A × 1.55 V × 1.11 form factor), even with Rth(j-c) = 1.8 °C/W, junction temperature rises ~20°C above case. Without heatsinking, safe current drops below 1 A RMS due to Rth(j-a) = 60 °C/W limiting thermal dissipation.
Can BTB06-600BWRG switch capacitive loads safely?
No-it is not rated for capacitive load switching. The device's snubberless design targets inductive and resistive loads only. Capacitive loads cause high inrush current and reverse recovery stress that exceed I²t = 21 A²s rating and may trigger destructive dv/dt-induced turn-on or latch-up.
Is BTB06-600BWRG compatible with zero-crossing trigger circuits?
Yes-its 5 mA IGT and 1000 V/µs dV/dt allow reliable triggering at or near zero-crossing points. However, zero-crossing operation limits it to ON/OFF control; phase-angle dimming requires precise gate timing within each half-cycle, which this triac supports fully in quadrants I, II, and III.
