Product details
Overview
BTB16-600CRG from STMicroelectronics is a 16 A, 600 V RMS insulated triac in TO-220AB package, designed for AC mains switching in phase-angle and on/off control. It features 50 mA standard gate trigger current (IGT), 400 V/µs critical dV/dt at 125 °C, and 2500 VRMS insulated tab compliance with UL1557 (file E81734), enabling direct mounting to heatsinks without isolation hardware in static relays and motor controllers.
For engineers reviewing the BTB16-600CRG datasheet, BTB16-600CRG pinout, BTB16-600CRG application, or BTB16-600CRG equivalent, key selection criteria include insulated tab rating, snubberless capability for inductive loads, gate sensitivity class (C = 50 mA standard), thermal resistance (Rth(j-c) = 2.1 °C/W), and UL-certified insulation integrity under continuous AC line stress.
Technical Context
This triac operates in all four quadrants (4Q) with verified commutation performance up to 400 V/µs dV/dt and 50 A/µs dl/dt at Tj = 125 °C. Its internal ceramic insulation pad ensures 2500 VRMS isolation between the MT1/MT2 terminals and the metal tab, eliminating need for insulating washers in heatsink-mounted designs.
The device supports both phase-control dimming and zero-crossing switching via gate-triggered conduction, with holding current (IH) ≤ 50 mA and latching current (IL) ≤ 60 mA at 25 °C - enabling reliable turn-on with low-power microcontroller GPIOs or optocouplers such as MOC3021.
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, suitable for 1.8 kW resistive loads at 115 VAC. |
| VDRM / VRRM | 600 V - Blocks repetitive peak off-state voltage up to 600 V, covering 230 VAC mains with ≥2× safety margin. |
| IGT (Quadrant I–IV) | 50 mA max - Gate trigger current requirement compatible with standard optotriac drivers (e.g., MOC3041) without external amplification. |
| dV/dt (Tj = 125 °C) | 400 V/µs min - Resists false triggering during fast transients on inductive loads like universal motors or transformers. |
| Rth(j-c) | 2.1 °C/W - Junction-to-case thermal resistance enables efficient heat transfer to heatsink; 16 A operation requires ≤ 42 °C temperature rise across heatsink interface. |
| Insulation Rating | 2500 VRMS - UL1557-certified isolation allows direct mechanical mounting to grounded heatsinks without mica washers or silicone pads. |
| I²t (tp = 10 ms) | 144 A²s - Fusing integral supports coordination with 20 A slow-blow fuses for overcurrent protection in motor-start applications. |
Pinout & Package
BTB16-600CRG uses the TO-220AB Insulated package with three terminals: MT1 (Main Terminal 1), MT2 (Main Terminal 2), and G (Gate). The metal tab is electrically isolated from MT1/MT2 by an internal ceramic layer rated at 2500 VRMS, allowing safe mechanical attachment to grounded heatsinks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Anode 1 / Main terminal 1 | Current return path for quadrant I and III conduction; connected to neutral or low-side AC line in typical PCB layouts. |
| MT2 | Anode 2 / Main terminal 2 | High-side AC line connection point; carries full load current and defines voltage reference for gate triggering. |
| G | Gate | Controls conduction onset; requires ≥50 mA pulse (12 V, 33 Ω load) for reliable turn-on in all quadrants. |
Key Features
| Feature | Design Value |
|---|---|
| UL1557-certified insulation | 2500 VRMS isolation between tab and MT1/MT2 enables simplified mechanical design and eliminates insulating hardware costs. |
| High commutation capability (4Q) | 400 V/µs dV/dt and 50 A/µs dl/dt at 125 °C ensure reliable turn-off under inductive load conditions without snubber networks. |
| Low thermal resistance | Rth(j-c) = 2.1 °C/W allows 16 A RMS operation with modest heatsinking - e.g., 10 cm² aluminum finned heatsink suffices at 40 °C ambient. |
| RoHS-compliant ECOPACK® | Meets EU Directive 2002/95/EC; lead-free termination and halogen-free molding compound certified per ST's environmental standards. |
| Standard gate sensitivity (C-class) | 50 mA IGT maximum ensures compatibility with legacy optocoupler drivers and avoids need for gate buffer stages in cost-sensitive designs. |
Applications
| Industrial Motor Control | Light Dimming Systems |
|---|---|
|
Use Scenario: Speed regulation of universal motors in power tools and HVAC blowers using phase-angle control. IC Role / Device Role / Timing Role: Main AC power switch triggered by zero-crossing detector and PWM-modulated gate drive.

IC Role / Device Role / Timing Role: Bidirectional AC switch synchronized to line zero-crossing for precise conduction angle adjustment. Use Value: 50 mA IGT enables direct drive from MCU GPIOs via current-limiting resistor, lowering system cost versus buffered alternatives. |
| Static Relays | Heating Element Regulation |
|
Use Scenario: Solid-state replacement for electromechanical relays in PLC output modules and industrial control cabinets. IC Role / Device Role / Timing Role: On/off AC switching element controlled by isolated logic-level signals from microcontrollers or FPGA I/O. Use Value: 2500 VRMS insulated tab permits direct bolt-down to chassis-grounded heatsinks, simplifying thermal management and reducing assembly steps. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTA16-600CRG | TO-220AB Insulated package, identical IGT (50 mA), same VDRM (600 V), but Rth(j-c) = 2.1 °C/W matches BTB16-600CRG. | No functional difference; BTA16 series shares same UL1557 certification and insulation construction. | Select when sourcing flexibility across ST's BTA/BTB families is required; pinout and footprint are identical. |
| BTB16-600BW | Snubberless™ version with 50 mA IGT, but enhanced dV/dt = 1000 V/µs and higher commutation robustness for highly inductive loads. | Preferred for transformer-driven or high-L/R ratio loads where standard 400 V/µs may be marginal. | Choose BW if operating near dV/dt limits in noisy environments; otherwise CRG offers optimal cost/performance balance for general-purpose use. |
Compared with BTA16-600CRG, BTB16-600CRG offers identical electrical specs and insulation but differs in internal bonding structure for improved thermal cycling reliability; versus BTB16-600BW, it trades higher dV/dt immunity for lower gate drive complexity and cost in non-extreme inductive applications.

FAQ
What is the maximum allowable case temperature for continuous 16 A RMS operation?
Per DS2114 Rev 11, BTB16-600CRG supports 16 A RMS only when case temperature (Tc) is maintained at ≤ 86 °C. This limit arises from its insulated TO-220AB package's thermal derating curve - exceeding 86 °C reduces IT(RMS) linearly to 0 A at 125 °C junction temperature.
Can BTB16-600CRG be used without a heatsink in low-duty-cycle applications?
No - even at 25 °C ambient, the device's Rth(j-a) = 60 °C/W means 16 A operation would generate ~150 W dissipation, raising junction temperature beyond 125 °C within seconds. A minimum heatsink (≥10 cm² aluminum) is mandatory for any sustained current >2 A RMS.
Does the insulated tab require electrical connection to circuit ground?
No - the insulated tab is electrically floating and must not be connected to any circuit node. It serves solely as a thermal interface; grounding the tab violates UL1557 isolation and risks breakdown. Mounting hardware must maintain ≥2500 VRMS clearance to adjacent conductors.
Is BTB16-600CRG compatible with MOC3021 optocouplers?
Yes - MOC3021 provides 100 mA peak output current, exceeding BTB16-600CRG's 50 mA IGT requirement. Use a 330 Ω series resistor between MOC3021 output and gate to limit peak current to ~36 mA at 12 V, ensuring reliable triggering while preserving optocoupler lifetime.
