Product details
Overview
BTB16-600BRG from STMicroelectronics is a 16 A, 600 V RMS insulated triac in TO-220AB package, designed for mains AC switching in phase-angle and on/off control. It features 50 mA gate trigger current (IGT), 2500 VRMS insulated tab, and high commutation capability (dV/dt ≥ 400 V/µs at 125 °C) for inductive loads without snubber circuits.
For engineers reviewing the BTB16-600BRG datasheet, BTB16-600BRG pinout, BTB16-600BRG application, or BTB16-600BRG equivalent, key selection criteria include insulated mounting requirement, 16 A thermal derating at 86 °C case temperature, Snubberless™ operation on motor loads, and UL1557 certification (file E81734).
Technical Context
This triac operates in all four quadrants with standard triggering logic and supports both phase-control dimming and zero-crossing switching. Its insulated TO-220AB package enables direct heatsink mounting without isolation hardware while maintaining 2500 VRMS creepage clearance.
Thermal performance is defined by Rth(j–c) = 2.1 °C/W (junction-to-case), enabling 16 A RMS conduction at Tc ≤ 86 °C. The device sustains 168 A non-repetitive surge (60 Hz, 16.7 ms) and exhibits critical dI/dt of 50 A/µs under specified gate drive conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 16 A - Sustained AC load current rating at Tc = 86 °C (insulated package limit) |
| VDRM / VRRM | 600 V - Peak repetitive off-state voltage; blocks full-wave 230 VAC mains with safety margin |
| IGT (Quadrant I/II/III/IV) | 50 mA max - Gate current required to trigger conduction; compatible with standard microcontroller GPIO |
| dV/dt (Tj = 125 °C) | ≥ 400 V/µs - Immunity to false turn-on during fast voltage transients on inductive loads |
| Rth(j–c) | 2.1 °C/W - Thermal resistance enabling efficient heatsink coupling; defines maximum power dissipation per °C rise |
| Insulation Rating | 2500 VRMS - Reinforced isolation between MT1/MT2 terminals and tab; eliminates need for insulating washers |
| UL Certification | UL1557 file E81734 - Confirms compliance with reinforced insulation standards for industrial end-equipment |
Pinout & Package
BTB16-600BRG uses the TO-220AB insulated package with three terminals: MT1 (Main Terminal 1), MT2 (Main Terminal 2), and Gate (G). The metal tab is electrically isolated from the die and rated for 2500 VRMS, allowing direct mechanical attachment to grounded heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Anode 1 / Main Terminal 1 | Primary current return path; referenced to gate for triggering in Quadrants I and II |
| MT2 | Anode 2 / Main Terminal 2 | Main current input terminal; polarity determines conduction quadrant behavior |
| G | Gate | Control input; 50 mA pulse triggers bidirectional conduction between MT1 and MT2 |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ commutation | Enables reliable switching on inductive loads (e.g., universal motors) without external RC snubbers |
| Insulated tab (2500 VRMS) | Eliminates need for mica washers or silicone pads; reduces assembly cost and thermal interface resistance |
| High dV/dt immunity (400 V/µs) | Prevents false triggering during line transients or motor back-EMF spikes in appliance applications |
| UL1557 certified (E81734) | Validates reinforced insulation integrity for safety-critical industrial and white-goods designs |
| RoHS-compliant ECOPACK® | Meets EU Directive 2002/95/EC; no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE |

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 |
|---|---|---|---|
| BTA16-600BRG | Same 16 A/600 V rating and insulated TO-220AB package, but 35 mA IGT (lower gate drive requirement) | Preferred where microcontroller GPIO has limited drive strength or when optimizing for lower gate power loss | Select if gate drive current budget is constrained below 50 mA; identical thermal and isolation specs |
| BTB16-600BW | Non-insulated TO-220AB package; same 50 mA IGT and 400 V/µs dV/dt, but requires insulating hardware for heatsink mounting | Suitable for cost-sensitive designs where isolation is achieved via external means (e.g., mica + grease) | Choose when board-level isolation strategy already includes insulating hardware and thermal interface optimization is prioritized |
Compared with BTB16-600BRG, BTA16-600BRG offers lower gate drive demand at identical isolation and current ratings, while BTB16-600BW trades built-in insulation for lower package cost and marginally better thermal resistance (Rth(j–c) = 1.2 °C/W vs. 2.1 °C/W).

FAQ
What is the maximum case temperature for continuous 16 A operation?
BTB16-600BRG supports 16 A RMS continuous current only up to Tc = 86 °C due to its insulated TO-220AB package construction. Exceeding this temperature requires linear derating per Figure 3 in DS2114 Rev 11; at 100 °C case temperature, maximum IT(RMS) drops to approximately 12.5 A.
Does BTB16-600BRG require a heatsink in all applications?
Yes-thermal analysis shows that even at 8 A RMS load, junction temperature exceeds 125 °C without heatsinking. With Rth(j–c) = 2.1 °C/W and Rth(c–a) ≈ 60 °C/W (unmounted), a heatsink with ≤ 10 °C/W thermal resistance is required to sustain 16 A at ambient temperatures above 40 °C.
Can BTB16-600BRG replace a non-insulated triac like BTB16-600B?
Yes, mechanically and electrically-but the insulated tab changes mounting requirements: BTB16-600BRG mounts directly to grounded heatsinks without insulators, whereas BTB16-600B requires mica/silicone isolation. No circuit redesign is needed, but mechanical layout must accommodate the insulated tab's voltage standoff.
Is BTB16-600BRG compliant with RoHS and REACH regulations?
Yes-BTB16-600BRG carries ST's ECOPACK®2 designation, confirming full compliance with RoHS Directive 2011/65/EU (including lead-free terminations) and REACH SVHC thresholds. Full material declarations and test reports are available through ST's official product page and Aetrix's compliance portal.
