Product details
Overview
BTB16-700SWRG from STMicroelectronics is a 16 A, 700 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 BTB16-700SWRG datasheet, BTB16-700SWRG pinout, BTB16-700SWRG application, or BTB16-700SWRG equivalent, key selection criteria include insulated thermal interface requirements, 3-quadrant triggering compatibility, gate drive current budget (<15 mA), and snubberless operation on reactive loads such as universal motors and solenoids.
Technical Context
This triac operates in 3-quadrant mode (QI, QII, QIII) with logic-level gate sensitivity (IGT ≤ 10 mA), enabling direct drive from microcontrollers or optocouplers without amplification. Its Snubberless™ architecture eliminates need for RC snubber networks by sustaining high critical dV/dt (400 V/µs) and dI/dt (8.5 A/ms) under worst-case commutation stress at Tj = 125 °C.
The insulated TO-220AB package integrates a ceramic isolation pad rated at 2500 VRMS between the tab and die, satisfying UL1557 (file E81734) and enabling safe mounting to grounded heatsinks. Thermal resistance Rth(j–c) is 2.1 °C/W, supporting 16 A RMS conduction at Tc ≤ 86 °C without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A - Sustains full-sine AC load current up to 16 A at case temperature ≤ 86 °C |
| VDRM / VRRM | 700 V - Blocks 700 V peak off-state voltage in both directions; compatible with 230 VAC + 15% surge |
| IGT (max) | 10 mA - Gate trigger current requirement low enough for direct MCU GPIO or PC817 optocoupler drive |
| dV/dt (min) | 400 V/µs - Withstands rapid voltage transients during zero-crossing commutation on inductive loads |
| Rth(j–c) | 2.1 °C/W - Enables efficient heat transfer to heatsink; allows 16 A operation with modest thermal design |
| Isolation Rating | 2500 VRMS - Ceramic-insulated tab permits safe mounting to chassis-grounded heatsinks per UL1557 |
| Commutation Type | 3Q Snubberless™ - Operates reliably without external snubber in QI/QII/QIII; excludes QIV triggering |
Pinout & Package
BTB16-700SWRG uses an insulated TO-220AB package with three leads: Main Terminal 1 (MT1), Main Terminal 2 (MT2), and Gate (G). The metal tab is electrically isolated from the die via internal ceramic substrate and rated for 2500 VRMS insulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Anode 1 / Cathode reference | Primary current return path; referenced to gate for triggering; polarity-sensitive in 3Q operation |
| MT2 | Anode 2 / Main power terminal | High-side AC line connection; carries full load current; electrically tied to insulated tab |
| G | Gate control input | Triggers conduction when ≥10 mA pulse applied relative to MT1; enables 3-quadrant firing only |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Eliminates external RC snubber components on inductive loads by sustaining 400 V/µs dV/dt and 8.5 A/ms dI/dt at 125 °C |
| UL1557-certified insulation | Internal ceramic pad provides 2500 VRMS isolation between tab and die, enabling safe chassis-mounting |
| Logic-level gate drive | 10 mA max IGT allows direct interface with 3.3 V/5 V MCUs or standard optocouplers (e.g., MOC3021, PC817) |
| Low thermal resistance | 2.1 °C/W junction-to-case enables 16 A RMS operation with passive heatsinking at Tc ≤ 86 °C |
| RoHS-compliant packaging | TO-220AB Ins. meets EU Directive 2002/95/EC; lead-free terminations and halogen-free molding compound |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-700SW | Same 16 A/700 V Snubberless™ specs but non-insulated TO-220AB package (Rth(j–c) = 1.2 °C/W) | Requires insulated mounting hardware or isolation pad when heatsink is grounded | Select when thermal performance priority outweighs isolation convenience; lower Rth(j–c) supports higher ambient temps |
| T1635-700G | D²PAK surface-mount package; 35 mA IGT; 500 V/µs dV/dt; Rth(j–c) = 1.2 °C/W; no tab isolation | Suitable for automated assembly; requires PCB copper area for thermal management; no built-in isolation | Select for space-constrained, reflow-soldered designs where board-level isolation can be engineered |
Compared with BTA16-700SW and T1635-700G, BTB16-700SWRG uniquely combines logic-level gate drive, snubberless inductive-load robustness, and certified 2500 VRMS tab isolation in a through-hole package - simplifying safety-compliant thermal and electrical integration in industrial AC controls.

FAQ
What does the 'SW' suffix signify in BTB16-700SWRG?
The 'SW' suffix denotes Snubberless™ and logic-level gate sensitivity (IGT ≤ 10 mA). This version sustains high commutation performance without external snubber networks and accepts low-current gate drive - distinct from standard 'B' (50 mA IGT) or 'CW' (35 mA IGT) variants. It is optimized for inductive loads like motors and solenoids.
Can BTB16-700SWRG replace a standard BTA16-600B in an existing design?
No - BTB16-700SWRG has different voltage rating (700 V vs. 600 V), gate sensitivity (10 mA vs. 50 mA), and insulation (insulated tab vs. non-insulated). Substitution requires verification of peak line voltage margins, gate drive capability, and mechanical mounting constraints. Its Snubberless™ behavior also alters transient response.
Is the insulated tab rated for continuous 2500 VRMS or only for dielectric testing?
The 2500 VRMS rating is a certified working insulation voltage per UL1557 (file E81734), not just a test value. It specifies sustained isolation between the tab and internal die under normal operating conditions - enabling safe mounting to grounded heatsinks in Class I appliances without additional barriers.
Does BTB16-700SWRG support four-quadrant triggering?
No - BTB16-700SWRG is a 3-quadrant triac (QI, QII, QIII only). Quadrant IV triggering is disabled to enhance commutation robustness and reduce false turn-on risk on inductive loads. Gate pulses must be referenced to MT1, and MT2 must be positive relative to MT1 for reliable turn-on.
