Product details
Overview
BTB16-600SWRG from STMicroelectronics is a 16 A, 600 V Snubberless™ triac in insulated TO-220AB package, designed for high-commutation AC mains switching in inductive loads. It features 10 mA gate trigger current (IGT), 2500 VRMS insulated tab, and 400 V/µs dV/dt capability at 125 °C - enabling reliable phase-angle control in motor speed controllers without external snubbers.
For engineers reviewing the BTB16-600SWRG datasheet, BTB16-600SWRG pinout, BTB16-600SWRG application, or BTB16-600SWRG equivalent, key selection criteria include insulated mounting compliance (UL1557), snubberless commutation performance on inductive loads, thermal resistance (Rth(j-c) = 2.1 °C/W), and gate sensitivity for microcontroller-driven triggering.
Technical Context
This triac operates in three quadrants (I, II, III) with logic-level gate drive (IGT ≤ 10 mA), enabling direct interface with low-power MCUs. Its Snubberless™ architecture eliminates need for RC snubber networks when switching inductive loads like universal motors or solenoids, reducing BOM count and board space.
Thermal design leverages an internal ceramic insulator rated at 2500 VRMS and junction-to-case thermal resistance of 2.1 °C/W, allowing safe operation up to 125 °C junction temperature under 16 A RMS load with appropriate heatsinking. The device meets UL1557 certification (file E81734) and RoHS 2002/95/EC compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A RMS - supports continuous mains switching for 1.8 kW resistive or 1.2 kW inductive loads at 230 VAC. |
| VDRM / VRRM | 600 V - withstands peak line voltage (≈848 V) with 40 % margin for 230 VAC systems. |
| IGT (max) | 10 mA - compatible with 3.3 V / 5 V MCU GPIOs without buffer stage. |
| dV/dt (min) | 400 V/µs at 125 °C - prevents false triggering during fast transients in noisy industrial environments. |
| Rth(j-c) | 2.1 °C/W - enables thermal management with standard TO-220 heatsinks for full-load operation. |
| Insulation rating | 2500 VRMS - satisfies reinforced insulation requirements for Class I appliances per IEC 60335. |
| (dI/dt)c | 8.5 A/ms - sustains rapid current rise during zero-crossing turn-on into highly inductive loads. |
Pinout & Package
BTB16-600SWRG uses an insulated TO-220AB package with creepage/clearance enhanced by internal ceramic pad. Mounting tab is electrically isolated and rated for 2500 VRMS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; connected to neutral or low-side return path in AC circuits. |
| A2 (MT2) | Main Terminal 2 | High-side AC line connection; carries full load current and defines polarity reference for gate triggering. |
| G | Gate | Controls conduction onset; requires ≥10 mA pulse (12 V, 30 Ω) for reliable turn-on in all quadrants. |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Enables direct switching of universal motors and transformers without RC snubber, reducing component count and failure points. |
| UL1557-certified insulation | 2500 VRMS isolated tab meets safety standards for household appliance motor controls and static relays. |
| Low IGT (10 mA) | Eliminates need for gate driver ICs; allows direct drive from STM32, ESP32, or PIC GPIOs with minimal current sourcing. |
| High dV/dt immunity | 400 V/µs at 125 °C ensures noise immunity in variable-speed drives and dimmer modules with EMI-prone environments. |
| RoHS-compliant ECOPACK® | Meets EU Directive 2002/95/EC; no lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE in packaging or die attach. |
Applications
| Universal Motor Speed Control | Static Relay Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac-based AC switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-600SWRG | Same specs but TO-220AB Insulated package; identical IGT, dV/dt, and insulation rating. | No mechanical difference; interchangeable where insulated mounting is required. | Select when footprint compatibility with existing BTA-series layouts is prioritized. |
| T1610-600G-TR | D²PAK surface-mount package; Rth(j-c) = 1.2 °C/W; same 10 mA IGT and 600 V rating. | Requires reflow assembly; better thermal performance but no insulated tab (non-isolated). | Choose for automated SMT production and higher power density, provided system-level isolation is handled externally. |
Compared with BTA16-600SWRG, BTB16-600SWRG offers identical electrical specs and insulation but differs in leadform orientation (BTB has straight leads, BTA has bent leads); versus T1610-600G-TR, it trades superior thermal resistance for mandatory external isolation design and manual through-hole assembly.

FAQ
What is the maximum junction temperature for BTB16-600SWRG?
The absolute maximum operating junction temperature is +125 °C, as specified in Table 1 of DS2114 Rev 11. Derating begins above Tc = 86 °C for the insulated TO-220AB package, and thermal design must ensure junction temperature remains within this limit under worst-case load and ambient conditions.
Does BTB16-600SWRG require a heatsink in all applications?
Yes - even at 16 A RMS, power dissipation exceeds 2 W (VTM ≈ 1.55 V × 16 A × conduction angle factor). With Rth(j-c) = 2.1 °C/W and Rth(c-a) highly dependent on PCB copper area, a minimum heatsink or ≥25 cm² copper pour is required to maintain Tj ≤ 125 °C at full load and 50 °C ambient.
Can BTB16-600SWRG be used in DC applications?
No - it is a bidirectional AC switch designed for mains-frequency commutation. In DC, it lacks natural current-zero crossing and will latch on indefinitely after triggering unless externally forced off via series switch or current interruption, risking thermal runaway.
Is the insulated tab rated for continuous 2500 VRMS or only for dielectric testing?
The 2500 VRMS rating is a continuous working voltage per UL1557 certification (file E81734), not just a test value. It applies to reinforced insulation between the tab and internal die, validated for lifetime operation in Class I appliances under pollution degree 2 conditions.
