Product details
Overview
BTA208X-600B from NXP Semiconductors is a planar passivated 3-quadrant high-commutation triac in TO-220F (SOT186A) package, rated for 600 V repetitive peak off-state voltage, 8 A RMS on-state current, and 65 A non-repetitive peak on-state current. It operates up to 125 °C junction temperature and commutates full rated current at max Tj without snubber, enabling robust AC switching in motor controls and thermostats.
For engineers reviewing the BTA208X-600B datasheet, BTA208X-600B pinout, BTA208X-600B application, or BTA208X-600B equivalent, key selection criteria include dV/dt immunity (4000 V/µs), gate trigger current range (2–50 mA across quadrants), isolated mounting base, snubberless commutation capability, and thermal resistance to heatsink (4.5 K/W with compound).
Technical Context
This 3Q Hi-Com triac uses planar passivation for voltage ruggedness and supports triggering only in quadrants I, II, and III-excluding QIV-to improve noise immunity and eliminate false turn-on. Its structure enables stable operation under high dV/dt (up to 4000 V/µs at 125 °C) and high dI/dt (100 A/µs), critical for inductive load switching.
The device features an isolated mounting base (2500 V RMS isolation voltage) and achieves snubberless commutation of 8 A RMS at 125 °C junction temperature. Gate trigger thresholds vary by quadrant: T2+G+ (2–50 mA), T2+G− (2–50 mA), and T2−G− (2–50 mA), ensuring predictable firing behavior in phase-control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 600 V - blocks 600 V peak AC line voltage, suitable for 230 V mains applications with safety margin |
| IT(RMS) | 8 A - delivers continuous 8 A RMS current into resistive or inductive loads with heatsink at ≤73 °C |
| ITSM | 65 A - withstands 65 A non-repetitive surge (20 ms, 50 Hz sine), sufficient for motor startup currents |
| dV/dt | 4000 V/µs - prevents false triggering during fast transients in noisy industrial environments |
| Rth(j-h) | 4.5 K/W - thermal resistance from junction to heatsink with thermal compound, enabling efficient heat transfer |
| VGT | 0.4 V typical - low gate trigger voltage ensures reliable firing even with weak drive sources |
| IGT | 2–50 mA - quadrant-dependent gate current requirement, defining minimum driver strength needed |
| VISO(RMS) | 2500 V - isolates terminals from heatsink, allowing safe chassis-mounting in grounded systems |
Pinout & Package
Package: TO-220F (SOT186A), plastic single-ended package with isolated mounting base, 1 mounting hole, and 3 leads. Mounting base is electrically isolated (2500 V RMS) and thermally conductive.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | T1 | Main terminal 1 - connects to load side of AC circuit; current path entry/exit depending on conduction quadrant |
| 2 | T2 | Main terminal 2 - connects to AC line side; forms primary current path with T1 during conduction |
| 3 | G | Gate - controls turn-on; requires quadrant-specific trigger pulse (T2+/T2−, G+/G−) per application |
| mb | Mounting base | Electrically isolated heatsink interface; provides thermal path without electrical connection to terminals |
Key Features
| Feature | Design Value |
|---|---|
| 3Q triggering only | Eliminates QIV sensitivity, improving EMI immunity and reducing false turn-on in noisy environments |
| Snubberless commutation | Commutes full 8 A RMS at 125 °C junction temperature without external RC snubber network |
| Isolated mounting base | 2500 V RMS isolation enables direct chassis mounting without insulating hardware or thermal pads |
| High dV/dt immunity | 4000 V/µs rating ensures stable blocking during fast line transients common in motor control and solenoid drive |
| Planar passivation | Enhances voltage ruggedness and long-term reliability under repeated overvoltage stress |
| High dI/dt capability | 100 A/µs rate-of-rise tolerance supports rapid turn-on into highly inductive DC motor loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB16-600BW | 16 A RMS rating, 4-pin TO-220 package (T1/T2/G/NC), higher IT(RMS), no isolated base | Requires insulating washer for heatsink mounting; suited for higher-current but less space-constrained designs | Select when >8 A RMS load current is required and mechanical isolation can be added externally |
| ON Semiconductor MAC15A8YG | 15 A RMS, 600 V, 3Q, TO-220AB package with non-isolated base, lower dV/dt (2000 V/µs) | Lacks 2500 V isolation; needs thermal pad for grounded heatsinks; reduced noise immunity in EMI-heavy settings | Choose for cost-sensitive, non-safety-critical 230 VAC switching where isolation is managed at system level |
Compared with BTA208X-600B, BTB16-600BW offers higher current capacity but requires external isolation, while MAC15A8YG trades isolation and dV/dt performance for cost and availability-making BTA208X-600B optimal for compact, safety-conscious, snubberless 8 A designs.

FAQ
What is the maximum junction temperature rating for the BTA208X-600B?
The BTA208X-600B has a maximum junction temperature (Tj) of 125 °C, validated for continuous operation at full 8 A RMS current when heatsink temperature remains ≤73 °C. This rating enables reliable use in enclosed, thermally constrained enclosures typical of thermostats and motor controllers.
Does the BTA208X-600B require a snubber circuit for commutation?
No-the BTA208X-600B is explicitly designed for snubberless commutation of its full rated 8 A RMS current at 125 °C junction temperature. Its high dIcom/dt (14 A/ms) and dV/dt (4000 V/µs) ratings eliminate the need for external RC networks in properly designed phase-control circuits.
What does "3Q" mean for the BTA208X-600B, and why does it matter?
"3Q" means the BTA208X-600B triggers only in quadrants I (T2+, G+), II (T2+, G−), and III (T2−, G−), excluding quadrant IV. This eliminates false turn-on caused by negative gate pulses during noise events, significantly improving noise immunity in industrial motor and solenoid applications.
Can the mounting base of the BTA208X-600B be directly connected to chassis ground?
Yes-the mounting base of the BTA208X-600B provides 2500 V RMS isolation from all terminals, allowing direct mechanical attachment to a grounded metal chassis without electrical isolation hardware. This simplifies thermal design and improves EMI shielding in compact enclosures.
What is the gate trigger current range for the BTA208X-600B across operating conditions?
The BTA208X-600B specifies gate trigger current (IGT) from 2 mA minimum to 50 mA maximum across all three quadrants at 25 °C, with typical values of 18 mA (T2+G+), 21 mA (T2+G−), and 34 mA (T2−G−). At 125 °C, normalized curves show IGT increases ~2×, requiring driver design to accommodate worst-case conditions.
