Product details
Overview
BTB16-600CWRG from STMicroelectronics is a 16 A, 600 V RMS insulated triac in TO-220AB package with Snubberless™ 3-quadrant operation, 35 mA gate trigger current (IGT), and 2500 VRMS isolation rating - designed for phase-angle control in inductive AC motor speed controllers and static relays.
For engineers reviewing the BTB16-600CWRG datasheet, BTB16-600CWRG pinout, BTB16-600CWRG application, or BTB16-600CWRG equivalent, key selection criteria include commutation robustness (dV/dt ≥ 500 V/µs at 125 °C), thermal resistance (Rth(j-c) = 2.1 °C/W), insulated tab compliance (UL1557 E81734), and Snubberless™ suitability for snubber-free inductive load switching.
Technical Context
This triac operates in 3-quadrant mode (QI, QII, QIII) with logic-compatible gate drive (VGT ≤ 1.3 V, IGT = 35 mA), enabling direct microcontroller interfacing without external amplification. Its Snubberless™ architecture eliminates external RC snubbers by sustaining high critical dV/dt (500 V/µs) and dI/dt (8.5 A/ms) under inductive stress at Tj = 125 °C.
The insulated TO-220AB package integrates a ceramic pad rated for 2500 VRMS isolation between tab and die, satisfying reinforced insulation requirements for mains-connected industrial controls. Junction-to-case thermal resistance 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 continuous 16 A RMS AC current at case temperature ≤ 86 °C in insulated TO-220AB package. |
| VDRM / VRRM | 600 V - Blocks 600 V peak repetitive off-state voltage in both directions, suitable for 230 VAC mains applications. |
| IGT (Quadrants I–III) | 35 mA max - Low gate drive requirement enables direct driving from MCU GPIO or optocoupler outputs. |
| (dV/dt)c @ 125 °C | 500 V/µs min - High commutation immunity prevents false triggering during fast voltage transients on inductive loads. |
| Rth(j-c) | 2.1 °C/W - Enables efficient heat transfer to heatsink; supports 16 A operation with modest thermal design. |
| Isolation Rating | 2500 VRMS - Reinforced insulation between tab and semiconductor die meets UL1557 (file E81734) for safety-critical AC interfaces. |
| ITSM (tp = 20 ms) | 160 A - Withstands 160 A non-repetitive surge current (e.g., motor startup inrush) without failure. |
Pinout & Package
BTB16-600CWRG uses an insulated TO-220AB package with three terminals: Main Terminal 1 (A1), Main Terminal 2 (A2), and Gate (G). The metal tab is electrically isolated from the die via internal ceramic insulation and rated for 2500 VRMS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Main Terminal 1 (Anode 1) | Reference terminal for gate trigger; connected to load return or neutral side in standard AC switch configurations. |
| A2 | Main Terminal 2 (Anode 2) | High-side AC line connection; carries full load current and defines polarity reference for quadrants I–III operation. |
| G | Gate | Controls conduction onset; triggers device in QI, QII, QIII only; requires ≥ 35 mA pulse for reliable turn-on at 25 °C. |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ 3Q operation | Eliminates need for external RC snubber networks on inductive loads - reduces BOM count and PCB area in motor controllers. |
| Insulated tab (2500 VRMS) | Enables safe mounting to grounded heatsinks without additional insulation hardware - simplifies mechanical design and improves thermal reliability. |
| Low IGT (35 mA) | Permits direct drive from low-power logic sources (e.g., STM32 GPIO, PC817 optocoupler output), reducing gate driver complexity. |
| High dV/dt immunity (500 V/µs) | Prevents spurious turn-on during voltage spikes from relay coil collapse or transformer switching - critical for stable operation in noisy industrial environments. |
| UL1557 certification | Validated insulation system (file E81734) satisfies safety agency requirements for Class I appliances and industrial AC power controls. |

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 |
|---|---|---|---|
| BTA16-600CWRG | Same IT(RMS), VDRM, IGT, and Snubberless™ spec; differs only in insulated (BTA) vs. non-insulated (BTB) package variant. | Requires insulated mounting hardware if used in BTB footprint; no tab isolation - unsuitable where chassis grounding is mandatory. | Select when board layout permits non-isolated tab mounting and cost optimization is prioritized over safety certification simplicity. |
| T1635-600G | D²PAK surface-mount package; identical 35 mA IGT and 500 V/µs dV/dt, but lower Rth(j-c) = 1.2 °C/W and no tab isolation. | Designed for automated SMT assembly; lacks 2500 VRMS isolation - requires external insulation for safety-critical mains interfaces. | Select for high-volume, space-constrained designs where thermal performance outweighs isolation needs and reflow compatibility is required. |
Compared with BTB16-600CWRG, BTA16-600CWRG offers identical electrical specs but mandates insulated mounting hardware, while T1635-600G trades isolation for superior thermal efficiency and SMT manufacturability - making BTB16-600CWRG optimal for through-hole, safety-certified, thermally moderate industrial controls.

FAQ
What is the maximum junction temperature for continuous operation?
The BTB16-600CWRG has a specified operating junction temperature range of –40 °C to +125 °C. Continuous conduction at 16 A RMS requires case temperature ≤ 86 °C due to its insulated TO-220AB thermal resistance (Rth(j-c) = 2.1 °C/W); exceeding this risks thermal runaway and latch-up.
Can BTB16-600CWRG be used without a heatsink?
No - at 16 A RMS, power dissipation exceeds 2.5 W even with low on-state voltage (VT ≤ 1.55 V). Without a heatsink, junction temperature will exceed 125 °C within seconds. A minimum heatsink with thermal resistance ≤ 15 °C/W (including interface resistance) is required for sustained operation.
Does the "W" suffix guarantee Snubberless™ operation in all quadrants?
Yes - the "W" suffix denotes Snubberless™ 3-quadrant operation (QI, QII, QIII only). It does not conduct in QIV, which enhances noise immunity and eliminates false triggering during negative half-cycle gate noise - confirmed by dV/dt ≥ 500 V/µs and (dI/dt)c ≥ 8.5 A/ms test data at 125 °C.
Is the insulated tab rated for functional or safety isolation?
The 2500 VRMS insulated tab is certified for safety isolation per UL1557 (file E81734), meaning it provides reinforced insulation between mains-connected A2 and earth-referenced heatsink/chassis - not merely functional separation. This enables compliance with IEC 61000-4-5 and IEC 60730 safety standards.
