Product details

Overview

BTA10-600BRG from STMicroelectronics is a 10 A, 600 V RMS insulated triac in TO-220AB package, designed for AC mains switching in phase-control and ON/OFF applications. It features Snubberless™ 3-quadrant operation, 50 mA gate trigger current (IGT), 1000 V/µs dV/dt immunity at 125 °C, and UL1557-certified 2500 VRMS isolation. Used in heating regulation, motor starting, and light dimmers with inductive loads.

For engineers reviewing the BTA10-600BRG datasheet, BTA10-600BRG pinout, BTA10-600BRG application, or BTA10-600BRG equivalent, key selection criteria include insulated tab rating, commutation robustness on inductive loads, thermal resistance (Rth(j-c) = 2.4 °C/W), and compatibility with zero-crossing or phase-angle control circuits.

Technical Context

This triac operates in three quadrants (I, II, III) with Snubberless™ capability, enabling reliable turn-off under high di/dt and low holding current conditions without external snubbers. Its internal ceramic insulation provides galvanic isolation between the main terminal (A2) and mounting tab, meeting UL1557 (file E81734).

Designed for 50/60 Hz AC line operation, it supports repetitive surge currents up to 105 A (60 Hz, 16.7 ms) and withstands non-repetitive off-state surges of 700 V (VDRM + 100 V). Gate sensitivity is optimized for logic-level drive (IGT ≤ 50 mA) while maintaining high dV/dt immunity (≥1000 V/µs at Tj = 125 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
IT(RMS)	10 A - Sustained AC load current handling at Tc = 95 °C with insulated TO-220AB package
VDRM / VRRM	600 V - Peak repetitive blocking voltage in both directions; suitable for 230 VAC mains with safety margin
IGT (max)	50 mA - Maximum gate trigger current required for turn-on; enables direct MCU GPIO drive with series resistor
dV/dt (min)	1000 V/µs - Critical rate of rise of off-state voltage immunity at 125 °C; eliminates need for snubber on inductive loads
Rth(j-c)	2.4 °C/W - Junction-to-case thermal resistance; defines heatsink sizing requirement for 10 A continuous operation
Isolation Rating	2500 VRMS - Reinforced insulation between A2 and tab per UL1557; enables safe chassis-mounting in Class I appliances
(dI/dt)c	9 A/ms - Minimum commutation di/dt capability without snubber; ensures reliable turn-off in motor and transformer loads

Pinout & Package

Package: TO-220AB Insulated - Through-hole, single-ended heat sink mount with electrically isolated metal tab rated at 2500 VRMS.

Pin/Terminal	Circuit Role	Design Meaning
A1 (MT1)	Main Terminal 1	Reference terminal for gate triggering; connected to load return or neutral side in typical AC switch configuration
A2 (MT2)	Main Terminal 2	High-side AC line connection; electrically isolated from tab; carries full load current
G	Gate	Control input for triggering conduction; requires ≥5 V pulse with ≥50 mA peak for guaranteed turn-on in QI/QII/QIII

Key Features

Feature	Design Value
Snubberless™ 3Q operation	Enables direct switching of inductive loads (e.g., fan motors, solenoids) without RC snubber networks, reducing BOM count and board space
UL1557-certified insulation	2500 VRMS isolation between A2 and tab meets appliance safety standards (IEC/EN 60335), eliminating need for additional creepage/clearance barriers
Low Rth(j-c) = 2.4 °C/W	Allows 10 A RMS operation with modest heatsinking (e.g., 10 cm² aluminum fin), supporting compact industrial control designs
High dV/dt immunity (1000 V/µs)	Prevents false triggering from line transients or commutation noise in noisy EMI environments like HVAC or power tools
RoHS-compliant ECOPACK®	Meets EU Directive 2002/95/EC; lead-free termination and halogen-free molding compound for environmentally regulated production

Applications

IC Role / Device Role / Timing Role: Bidirectional AC switch modulating RMS voltage via leading-edge phase control; gate driven by optocoupler-isolated TRIAC driver IC.

Use Value: Delivers silent, jitter-free dimming down to 5% brightness with no external snubber, reducing component count and EMI filter complexity.

Induction Motor Starting

Static Relay Replacement

Use Scenario: Soft-start and run control of single-phase induction motors in washing machines, compressors, and pumps.

IC Role / Device Role / Timing Role: High-current AC switch replacing electromechanical contactors; triggered by timing-controlled gate pulses to limit inrush current.

Use Scenario: Solid-state replacement of mechanical relays in programmable logic controllers (PLCs), building automation panels, and test equipment.

IC Role / Device Role / Timing Role: Isolated load switch providing galvanically separated control path; tab mounted directly to grounded chassis for EMC robustness.

Use Value: Eliminates relay chatter, bounce, and contact oxidation; supports 1 kHz switching frequency for rapid test sequencing in automated systems.

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	Same 10 A / 600 V rating but non-insulated TO-220AB package; Rth(j-c) = 1.5 °C/W; no UL-rated isolation	Requires insulated mounting hardware or PCB barrier for safety-critical applications; unsuitable for direct chassis mounting	Select when thermal performance is prioritized over isolation, and system-level insulation is handled elsewhere
T1050-6G	D²PAK surface-mount package; same Snubberless™ 3Q spec; IGT = 50 mA; Rth(j-c) = 1.5 °C/W; no isolation	Enables automated assembly and higher board density; lacks reinforced insulation; requires external isolation for safety compliance	Select for space-constrained, high-volume consumer electronics where reflow compatibility and footprint reduction outweigh isolation needs

Compared with BTA10-600BW and T1050-6G, the BTA10-600BRG uniquely delivers certified 2500 VRMS isolation in a through-hole package-making it the only choice for Class I appliance designs requiring intrinsic tab isolation without added safety components.

FAQ

What is the maximum junction temperature for continuous operation?

The BTA10-600BRG has an operating junction temperature range of –40 °C to +125 °C. Continuous conduction at 10 A RMS requires case temperature ≤95 °C, enforced by thermal design using its 2.4 °C/W junction-to-case resistance and appropriate heatsinking.

Does the insulated tab require electrical connection to circuit ground?

No-the insulated tab is electrically floating and rated for 2500 VRMS isolation from A2. It may be mounted directly to a grounded metal chassis for thermal management without compromising safety isolation, per UL1557 file E81734.

Can this triac replace a standard 4-quadrant triac in existing designs?

Yes, but only in quadrant I, II, and III operation. The BTA10-600BRG is a 3-quadrant Snubberless™ device and does not support quadrant IV triggering. Gate drive must avoid negative gate pulses relative to A1 to prevent undefined behavior.

What is the minimum gate trigger voltage required?

VGT is guaranteed ≤1.3 V at 25 °C (Table 3). At 125 °C, VGT remains ≤1.3 V, ensuring compatibility with 3.3 V and 5 V logic outputs. A series resistor of 100 Ω limits gate current to ~40 mA when driven from a 5 V source, satisfying IGT ≤50 mA.
