Product details
Overview
BTA16-600BW from STMicroelectronics is a 16 A, 600 V Snubberless™ insulated triac in TO-220AB Insulated package, designed for high-commutation AC mains switching in inductive loads. It features 50 mA gate trigger current (IGT), 1000 V/µs critical dV/dt (Tj = 125 °C), and 2500 VRMS insulated tab compliance with UL1557 (file E81734), enabling direct mounting on heatsinks without isolation hardware in motor speed controllers.
For engineers reviewing the BTA16-600BW datasheet, BTA16-600BW pinout, BTA16-600BW application, or BTA16-600BW equivalent, key selection criteria include snubberless commutation capability for inductive loads, insulated tab voltage rating, gate sensitivity class (BW = 50 mA Snubberless™), thermal resistance (Rth(j-c) = 2.1 °C/W), and TO-220AB Insulated mechanical compatibility.
Technical Context
This triac operates in three quadrants (I, II, III) with Snubberless™ architecture, eliminating external snubbers for inductive load commutation. Its internal ceramic insulation enables 2500 VRMS isolation between tab and MT1/MT2 terminals, meeting UL1557 safety requirements without additional barriers.
The device delivers 16 A RMS on-state current at Tc = 86 °C, supports non-repetitive surge currents up to 168 A (60 Hz, 16.7 ms), and maintains stable latching (IL ≤ 70 mA) and holding (IH ≤ 50 mA) performance across -40 to +125 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A RMS on-state current at case temperature 86 °C - defines continuous AC load handling capacity under thermal constraint |
| VDRM / VRRM | 600 V peak repetitive off-state voltage - ensures reliable blocking of 230 VAC mains with safety margin |
| IGT (Snubberless™) | 50 mA max gate trigger current - enables direct drive from microcontroller GPIO or low-power optocouplers |
| (dV/dt)c | 1000 V/µs min critical rate-of-rise at Tj = 125 °C - prevents false triggering during fast transients on inductive loads |
| Rth(j-c) | 2.1 °C/W junction-to-case thermal resistance - determines heatsink sizing requirement for 86 °C case temperature limit |
| Insulation Rating | 2500 VRMS tab-to-terminal isolation - eliminates need for insulating washers when mounting to grounded heatsinks |
| UL Certification | UL1557 certified (E81734) - validates safety compliance for end-equipment certification in North America |
Pinout & Package
TO-220AB Insulated package with electrically isolated metal tab (2500 VRMS). Mounting hole accepts M3 screw; recommended torque 0.55 N·m (max 0.70 N·m). Tab is internally connected to MT2 terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 (Main Terminal 1) | Anode 1 / return path for main current | Connected to load neutral or low-side return; referenced as ground in phase-angle control circuits |
| MT2 (Main Terminal 2) | Anode 2 / high-side main current path | Internally bonded to insulated tab; must be isolated from chassis unless using certified heatsink interface |
| G (Gate) | Trigger control input | Accepts 50 mA pulse to initiate conduction; polarity-sensitive in Quadrants I/II/III; no gate current required during conduction |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Enables direct switching of inductive loads (e.g., universal motors, solenoids) without external RC snubber networks, reducing BOM count and board space |
| UL1557-certified insulation | 2500 VRMS isolation validated per UL standard - allows safe integration into Class I appliances without additional creepage/clearance design effort |
| Low thermal resistance | 2.1 °C/W junction-to-case enables 16 A operation at 86 °C case temperature with moderate heatsinking |
| High dV/dt immunity | 1000 V/µs critical dV/dt rating at 125 °C junction temperature prevents spurious turn-on during line transients or zero-crossing noise |
| RoHS-compliant ECOPACK® | Meets EU Directive 2002/95/EC - supports environmental compliance for global market deployment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-600CW | 35 mA IGT (vs. 50 mA), 500 V/µs dV/dt (vs. 1000 V/µs) | Lower gate drive requirement but reduced commutation robustness on highly inductive loads | Select when driving from ultra-low-power optocouplers (e.g., PC817) and load inductance is moderate (e.g., small fans) |
| T1650-600G | D²PAK surface-mount package, Rth(j-c) = 1.2 °C/W, same 50 mA IGT and 1000 V/µs dV/dt | No insulated tab; requires PCB isolation or external insulator for heatsink mounting | Select for automated SMT assembly and higher power density where board-level isolation is feasible |
Compared with BTA16-600CW, the BTA16-600BW offers superior inductive load immunity due to its higher dV/dt rating; compared with T1650-600G, it provides integrated 2500 VRMS isolation but requires through-hole assembly and larger footprint.

FAQ
What does the 'BW' suffix indicate in BTA16-600BW?
The 'BW' suffix denotes a Snubberless™ triac with 50 mA gate trigger current (IGT) and TO-220AB Insulated package. It confirms compliance with UL1557 (E81734), 2500 VRMS tab isolation, and three-quadrant operation optimized for inductive load commutation without external snubbers.
Can BTA16-600BW replace a standard BTA16-600B in an existing design?
Yes, but only if the original design uses the insulated TO-220AB variant and benefits from Snubberless™ operation. The BW version has identical pinout and package dimensions but higher dV/dt (1000 V/µs vs. 400 V/µs for B) and lower IGT (50 mA vs. 25 mA for standard B), requiring gate drive verification for compatibility.
Is heatsink mounting mandatory for BTA16-600BW at 16 A RMS?
Yes. At 16 A RMS, junction temperature exceeds safe limits without heatsinking. With Rth(j-c) = 2.1 °C/W and max Tj = 125 °C, a heatsink maintaining Tc ≤ 86 °C is required - typically a 10–15 cm² aluminum finned heatsink with thermal interface material.
Does BTA16-600BW support four-quadrant triggering?
No. BTA16-600BW is a three-quadrant Snubberless™ triac (Quadrants I, II, III only). It does not support reliable triggering in Quadrant IV, unlike standard four-quadrant triacs such as BTA16-600C. This design improves noise immunity and commutation performance on inductive loads.
