Product details
Overview
BTB16-800SWRG from STMicroelectronics is a 16 A, 800 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 critical dV/dt at 125 °C - enabling reliable phase-angle control without external snubbers in motor speed controllers and static relays.
For engineers reviewing the BTB16-800SWRG datasheet, BTB16-800SWRG pinout, BTB16-800SWRG application, or BTB16-800SWRG equivalent, this part is selected for snubberless operation on inductive AC loads where high commutation robustness, thermal resistance <2.1 °C/W (j-c), and UL1557-certified insulation are mandatory design requirements.
Technical Context
This triac operates in three quadrants (I, II, III) with logic-level gate sensitivity (IGT ≤ 10 mA), enabling direct drive from microcontrollers or optocouplers without buffer stages. Its Snubberless™ architecture eliminates need for RC snubber networks by sustaining ≥400 V/µs dV/dt and ≥8.5 A/ms critical di/dt under worst-case inductive turn-off conditions at Tj = 125 °C.
The insulated TO-220AB package integrates a ceramic pad rated for 2500 VRMS isolation between tab and die, meeting UL1557 (file E81734) and enabling safe mounting to grounded heatsinks in Class I appliances. Thermal resistance Rth(j–c) is 2.1 °C/W, supporting 16 A RMS conduction at Tc ≤ 86 °C without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A RMS - supports continuous mains switching up to 3.5 kW resistive or 2.2 kW inductive load at 230 VAC |
| VDRM / VRRM | 800 V - withstands peak line voltage (±325 V) plus 100 V surge per IEC 61000-4-5 |
| IGT (max) | 10 mA - compatible with low-power gate drivers (e.g., MOC3021, IL420) without amplification |
| dV/dt (min) | 400 V/µs @ 125 °C - prevents false triggering during fast transients in motor or transformer circuits |
| Rth(j–c) | 2.1 °C/W - enables 16 A operation with ≤135 °C junction rise over 86 °C case temperature |
| Isolation Voltage | 2500 VRMS - permits direct mounting to chassis-grounded heatsinks in UL/EN 60335-compliant appliances |
| UL Certification | UL1557 file E81734 - validated insulation system for safety-critical consumer and industrial equipment |
Pinout & Package
BTB16-800SWRG uses an insulated TO-220AB package with metal tab electrically isolated from the die via internal ceramic pad. Mounting torque: 0.55 N·m (recommended), max 0.70 N·m. Tab is rated 2500 VRMS isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (MT1) | Main Terminal 1 | Reference terminal for gate trigger; connected to neutral or low-side of AC load |
| A2 (MT2) | Main Terminal 2 | High-side AC line connection; carries full load current and must be routed with creepage/clearance compliance |
| G | Gate | Logic-level input (≤10 mA IGT); polarity-insensitive for 3Q operation; requires 12 V pulse with 30 Ω series resistor |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Rated for inductive loads without external RC snubber - reduces BOM count and PCB area in motor controls |
| Insulated tab (2500 VRMS) | Enables safe, direct mounting to grounded heatsinks - eliminates need for insulating washers in Class I enclosures |
| Low IGT (10 mA max) | Direct interface with standard optotriacs (e.g., MOC3041) and MCU GPIO - no gate driver IC required |
| High dV/dt immunity (400 V/µs) | Immune to false triggering from switching noise in variable-speed drives and dimmer circuits |
| UL1557 certified | Validated insulation system meets appliance safety standards - accelerates end-product certification |

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 |
|---|---|---|---|
| BTA16-800SWRG | Same 16 A/800 V/10 mA specs but TO-220AB Insulated package - identical Rth(j–c) and isolation rating | No difference: interchangeable in all designs requiring insulated tab and snubberless operation | Select when sourcing flexibility across ST's BTA/BTB families is needed; same footprint and thermal performance |
| T1610-800G-TR | D²PAK surface-mount package; 10 mA IGT, 800 V, but Rth(j–c) = 1.2 °C/W and no tab isolation | Requires isolated gate drive and external insulation for chassis mounting; suited for space-constrained SMT designs | Choose only for automated assembly and higher power density; not drop-in for TO-220AB layouts or grounded-heatsink use |
Compared with BTB16-800SWRG, BTA16-800SWRG offers identical electrical and safety specs in the same package, while T1610-800G-TR trades isolation and through-hole compatibility for lower thermal resistance and SMT manufacturability - making BTB16-800SWRG optimal for safety-critical, thermally demanding, through-hole industrial controls.

FAQ
What is the maximum junction temperature for continuous operation?
The BTB16-800SWRG has a specified operating junction temperature range of –40 °C to +125 °C. For continuous 16 A RMS conduction, case temperature must be held ≤86 °C per absolute maximum ratings table - achieved using a heatsink with thermal resistance ≤1.1 °C/W (including interface resistance) when ambient is 40 °C.
Can BTB16-800SWRG replace a standard BTA16-800B in an existing design?
No - BTB16-800SWRG is a Snubberless™ variant with 10 mA IGT and 400 V/µs dV/dt, whereas BTA16-800B is a standard 50 mA IGT, 200 V/µs triac. Direct substitution risks insufficient gate drive and false triggering; redesign of gate circuit and snubber removal is required.
Is the insulated tab rated for continuous 2500 VRMS or just dielectric strength test?
Yes - the 2500 VRMS rating is a continuous working voltage per UL1557 certification (file E81734), not just a one-time dielectric test. It specifies sustained isolation capability between tab and die under normal operating conditions, including humidity and pollution degree 2 environments.
Does BTB16-800SWRG support four-quadrant triggering?
No - BTB16-800SWRG is a three-quadrant (3Q) Snubberless™ triac, triggered only in quadrants I, II, and III. It does not support quadrant IV triggering, which is reserved for standard (non-Snubberless™) versions like BTB16-800B/C. This improves noise immunity in inductive applications.
