Product details
Overview
BTB10-600BWRG from STMicroelectronics is a 10 A, 600 V Snubberless™ triac in TO-220AB insulated package, designed for robust AC mains switching in inductive loads. It delivers 50 mA gate trigger current (IGT), 1000 V/µs critical dV/dt (quadrants I–III), and 2500 VRMS isolation rating - enabling direct use in motor starters and heating controls without external snubbers.
For engineers reviewing the BTB10-600BWRG datasheet, BTB10-600BWRG pinout, BTB10-600BWRG application, or BTB10-600BWRG equivalent, key selection criteria include its 3-quadrant Snubberless™ commutation capability, UL1557-certified insulated tab, thermal resistance of 2.4 °C/W (j-c), and compatibility with phase-control dimming and static relay replacement in industrial AC power systems.
Technical Context
This triac operates as a bidirectional AC switch with gate-controlled turn-on in quadrants I, II, and III only - eliminating quadrant IV conduction to improve noise immunity and commutation reliability on inductive loads. Its internal ceramic insulation enables 2500 VRMS isolation between MT1/MT2 terminals and the metal tab, satisfying reinforced insulation requirements per UL1557 (file E81734).
The device 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 applications such as appliance motor speed control and solid-state relays where load transients demand stable turn-off behavior without snubber networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(RMS) | 10 A RMS - supports continuous mains-load switching up to 2.4 kW at 240 VAC. |
| VDRM / VRRM | 600 V - withstands peak line voltage surges in 230 VAC nominal systems with safety margin. |
| IGT (max) | 50 mA - compatible with standard microcontroller GPIO or optocoupler drivers without amplification. |
| dV/dt (min) | 1000 V/µs - prevents false triggering during rapid voltage transients on inductive loads. |
| Rth(j-c) | 2.4 °C/W - enables 10 A operation at Tc ≤ 95 °C with minimal heatsinking. |
| Isolation Rating | 2500 VRMS - meets reinforced insulation requirements for Class I appliances per UL1557. |
| (dI/dt)c | 9 A/ms - sustains high-current turn-on without commutation failure in motor-start circuits. |
Pinout & Package
BTB10-600BWRG uses the TO-220AB insulated package with electrically isolated metal tab. The tab is internally connected to MT2 and rated for 2500 VRMS isolation from circuit ground - enabling direct mounting to heatsinks without insulating washers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MT1 | Main Terminal 1 | AC line input or load return path; referenced to gate for triggering. |
| MT2 | Main Terminal 2 | Connected to insulated metal tab; serves as common AC output or neutral-side connection. |
| G | Gate | Low-power control input; triggers conduction when IGT ≥ 50 mA applied between G and MT1. |
Key Features
| Feature | Design Value |
|---|---|
| Snubberless™ 3Q operation | Enables reliable commutation on inductive loads (e.g., motors, transformers) without external RC snubbers. |
| UL1557-certified insulation | 2500 VRMS isolation between MT2/tab and PCB ground satisfies safety standards for Class I equipment. |
| Low Rth(j-c) | 2.4 °C/W allows full 10 A RMS current handling at case temperature ≤95 °C with modest heatsinking. |
| High dV/dt immunity | 1000 V/µs minimum ensures immunity to line-edge transients in 50/60 Hz AC environments. |
| 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 |
|---|---|---|---|
| BTA10-600BWRG | Same IT(RMS), VDRM, IGT, and Snubberless™ spec; non-insulated TO-220AB package (tab connected to MT2). | Requires insulating hardware for heatsink mounting; lower Rth(j-c) = 1.5 °C/W but no isolation. | Select when isolation is unnecessary and thermal performance is prioritized over safety certification. |
| T1050-6G | D²PAK surface-mount package; identical 10 A/600 V/50 mA Snubberless™ specs; Rth(j-c) = 1.5 °C/W. | Suitable for automated assembly; lacks insulated tab - requires PCB-level isolation for safety-critical designs. | Select for space-constrained, high-volume SMT production where board-level isolation can be engineered. |
Compared with BTA10-600BWRG and T1050-6G, BTB10-600BWRG uniquely combines UL-certified 2500 VRMS insulation, TO-220AB through-hole reliability, and Snubberless™ inductive-load robustness - making it optimal for safety-regulated, thermally demanding, and serviceable AC power modules.

FAQ
What is the isolation voltage rating of BTB10-600BWRG, and how is it certified?
BTB10-600BWRG provides 2500 VRMS reinforced insulation between MT2 and the metal tab, verified per UL1557 (file E81734). This rating is achieved via an internal alumina ceramic pad and enables direct heatsink mounting without additional insulation hardware in Class I appliances.
Can BTB10-600BWRG replace a standard 4-quadrant triac in existing designs?
Yes, but only if the application operates exclusively in quadrants I–III and does not rely on quadrant IV triggering. BTB10-600BWRG is a 3-quadrant Snubberless™ device - its quadrant IV blocking improves noise immunity but removes one trigger path; verify gate drive polarity and load characteristics before substitution.
What is the maximum allowable case temperature for continuous 10 A RMS operation?
The datasheet specifies IT(RMS) = 10 A at Tc = 95 °C for the insulated TO-220AB package. Exceeding this temperature reduces safe operating current - derating curves in Figure 3 confirm 7.5 A RMS at Tc = 110 °C, requiring thermal design validation for ambient/heatsink conditions.
Does BTB10-600BWRG require a snubber network when driving inductive loads?
No. Its Snubberless™ design guarantees commutation capability up to 9 A/ms (dI/dt)c at 125 °C, eliminating the need for external RC snubbers in typical motor and transformer applications - reducing BOM count, board space, and failure points in AC power stages.
