Product details

Overview

BTB10-600BRG from STMicroelectronics is a 10 A, 600 V Snubberless™ triac in insulated TO-220AB package, rated for 2500 VRMS isolation, designed for robust AC mains switching in inductive loads without external snubbers. It delivers 50 mA gate trigger current (IGT), 1000 V/µs dV/dt immunity at 125 °C, and supports phase control in motor speed controllers and heating regulation.

For engineers reviewing the BTB10-600BRG datasheet, BTB10-600BRG pinout, BTB10-600BRG application, or BTB10-600BRG equivalent, this page provides verified thermal resistance (Rth(j-c) = 2.4 °C/W), commutation performance (dI/dt ≥ 9 A/ms), insulation rating, and real-world use cases in static relays and induction motor starting circuits.

Technical Context

This triac operates in three quadrants (Q1, Q2, Q3) with Snubberless™ architecture, enabling reliable turn-off under high inductive load stress without external RC networks. Its internal ceramic insulation pad ensures UL1557 compliance (file E81734) and 2500 VRMS isolation between tab and die.

It features a low dynamic on-state resistance (RD ≤ 40 mΩ at 125 °C) and high critical rate of rise of on-state current (dl/dt ≥ 50 A/µs), supporting fast-switching phase-control applications while maintaining stable latching (IL ≤ 70 mA) and holding (IH ≤ 50 mA) behavior across -40 to +125 °C junction temperature range.

Key Specifications

Parameter	Value and Actual Design Meaning
IT(RMS)	10 A RMS - supports continuous 120/230 VAC load switching up to 2.3 kW resistive or 1.8 kW inductive.
VDRM / VRRM	600 V - withstands peak line voltages up to 848 V (230 VAC) or 170 V (120 VAC) with safety margin.
IGT (max)	50 mA - compatible with standard microcontroller GPIO or optocoupler drivers without amplification.
dV/dt (min)	1000 V/µs at 125 °C - eliminates false triggering in noisy industrial environments with fast voltage transients.
Rth(j-c)	2.4 °C/W - enables 10 A operation at Tc ≤ 95 °C with minimal heatsinking (e.g., 15 cm² aluminum).
(dI/dt)c	9 A/ms - sustains rapid current rise during motor startup without commutation failure on inductive loads.
Isolation Rating	2500 VRMS - meets reinforced insulation requirements for Class I appliances and industrial controls.

Pinout & Package

BTB10-600BRG uses an insulated TO-220AB package with electrically isolated metal tab (rated 2500 VRMS). The tab serves as the A2 terminal and must be mounted to heatsink without conductive thermal interface unless isolation is maintained.

Pin/Terminal	Circuit Role	Design Meaning
A1	Main Terminal 1	Reference node for gate drive; connected to load return or neutral side in AC switching topologies.
A2	Main Terminal 2	Isolated tab - connects to AC line/hot side; requires non-conductive mounting hardware and thermal pad.
G	Gate	Low-energy trigger input; accepts 50 mA pulse to initiate conduction in Q1/Q2/Q3; sensitive to polarity.

Key Features

Feature	Design Value
Snubberless™ 3-quadrant operation	Enables direct drive of inductive loads (e.g., fan motors, solenoids) without external snubber components, reducing BOM count and board space.
UL1557-certified insulation	2500 VRMS isolation (file E81734) allows use in double-insulated consumer appliances and industrial equipment without additional barrier design.
High commutation robustness	(dI/dt)c ≥ 9 A/ms at 125 °C ensures reliable turn-off during zero-crossing interruption of high-inductance loads like transformer primaries.
Low thermal resistance	Rth(j-c) = 2.4 °C/W permits full 10 A RMS current handling at case temperatures ≤ 95 °C using compact heatsinks.

Applications

Induction Motor Starting

Heating Regulation

Use Scenario: Controlling startup surge and run current of single-phase induction motors in HVAC blowers and washing machine pumps.

IC Role / Device Role / Timing Role: Triac acting as bidirectional AC switch triggered at precise phase angle to limit inrush and enable soft-start.

Use Value: Eliminates need for separate start capacitor and centrifugal switch; Snubberless™ operation prevents commutation failure during abrupt current decay.

Use Scenario: Regulating power to resistive heating elements in ovens, water heaters, and soldering irons via phase-angle control.

IC Role / Device Role / Timing Role: Main AC power switch modulated by microcontroller-generated zero-crossing synchronized gate pulses.

Use Value: Delivers smooth, flicker-free power control with 10 A RMS capacity and thermal stability up to 125 °C junction temperature.

Static Relay Replacement

Light Dimmer Control

Use Scenario: Solid-state replacement for electromechanical relays in PLC output modules and building automation systems.

IC Role / Device Role / Timing Role: Isolated AC switching element providing ON/OFF control with galvanic separation between logic and load sides.

Use Value: 2500 VRMS isolation and 100 A non-repetitive surge rating ensure long life and reliability in 24/7 industrial duty cycles.

Use Scenario: Mains-connected leading-edge dimmer circuit for incandescent and halogen lamps in residential lighting.

IC Role / Device Role / Timing Role: Phase-controlled AC switch triggered after zero-crossing to adjust RMS voltage delivered to lamp filament.

Use Value: 1000 V/µs dV/dt immunity prevents false triggering from line noise; low IGT simplifies driver design with standard optocouplers.

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
BTA10-600BW	Non-insulated TO-220AB package; Rth(j-c) = 1.5 °C/W; same 10 A/600 V/Snubberless™ specs.	Requires conductive heatsink mounting; unsuitable where reinforced isolation is mandated (e.g., Class II appliances).	Select when thermal performance is prioritized over isolation and system-level creepage/clearance allows direct tab grounding.
T1050-6G	D²PAK surface-mount package; 10 A/600 V/50 mA IGT; Rth(j-c) = 1.5 °C/W; no isolation (tab = A2).	Designed for automated assembly and compact PCB layouts; lacks 2500 VRMS isolation; lower profile than TO-220AB.	Choose for space-constrained, high-volume SMT designs where isolation is handled at board level (e.g., via slotting or coating).

Compared with BTA10-600BW and T1050-6G, BTB10-600BRG uniquely combines mandatory reinforced isolation (2500 VRMS), through-hole mechanical robustness, and Snubberless™ inductive load capability-making it the only choice for safety-critical, field-serviceable AC control modules.

FAQ

What is the maximum junction temperature for BTB10-600BRG?

The absolute maximum operating junction temperature (Tj) is +125 °C, with storage temperature extending to +150 °C. Derating begins above Tc = 95 °C per Table 1, requiring heatsink design to maintain Tj ≤ 125 °C under full 10 A RMS load.

Does BTB10-600BRG require a heatsink in all applications?

Yes - even at 10 A RMS, power dissipation exceeds 2 W. With Rth(j-c) = 2.4 °C/W and ambient limits, a heatsink is mandatory to keep Tj ≤ 125 °C. Minimum recommended heatsink thermal resistance is 15 °C/W for continuous operation at 230 VAC.

Can BTB10-600BRG replace a standard 4-quadrant triac?

No - BTB10-600BRG is a 3-quadrant Snubberless™ device (Q1/Q2/Q3 only); it cannot trigger in quadrant IV. Use only in circuits where gate drive polarity avoids Q4 conduction, such as zero-crossing or phase-control topologies with unidirectional gate signals.

What does the "RG" suffix indicate in BTB10-600BRG?

"RG" denotes tube packaging (50 pcs/tube) and confirms the part is supplied in insulated TO-220AB format ("B" = insulated, "600" = 600 V, "BW" = 50 mA Snubberless™ sensitivity). It is not a RoHS designation - all variants comply with RoHS 2002/95/EC.
