Product details
Overview
BTA202X-800E from NXP Semiconductors is a planar passivated 3-quadrant high-commutation triac in TO-220F (SOT186A) package, rated for 800 V repetitive peak off-state voltage and 2 A RMS on-state current. It features sensitive gate triggering (0.5–10 mA), 500 V/µs dV/dt immunity, and isolated mounting base - designed for direct interfacing with microcontrollers in AC load switching applications such as appliance motor controls.
For engineers reviewing the BTA202X-800E datasheet, BTA202X-800E pinout, BTA202X-800E application, or BTA202X-800E equivalent, this page delivers verified triac specifications, three-quadrant triggering behavior, snubberless commutation capability, thermal resistance data (Rth(j-h) = 5.5 K/W), and isolation voltage (2500 VRMS) - all critical for reliable AC power control design.
Technical Context
The BTA202X-800E employs 3Q (three-quadrant) triggering architecture, enabling gate control only in quadrants I, II, and III - eliminating false turn-on from quadrant IV noise. Its planar passivation ensures voltage ruggedness up to 800 VDRM, while the isolated heatsink-mountable TO-220F package supports safe operation in grounded-chassis systems.
It delivers snubberless commutation performance with dIcom/dt ≥ 2 A/ms at 125 °C and 400 V, and maintains stable gate trigger current (IGT) across –50 °C to 125 °C junction temperature range. The device operates without external snubbers in highly inductive loads when used within its IT(RMS) = 2 A and Tj ≤ 125 °C limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM | 800 V - maximum repetitive blocking voltage; enables use in 230 V AC mains with safety margin. |
| IT(RMS) | 2 A - continuous RMS current rating at heatsink temperature ≤ 110 °C; defines steady-state load capacity. |
| IGT | 0.5–10 mA - gate trigger current range at 25 °C; ensures compatibility with 3.3 V/5 V microcontroller GPIOs. |
| dV/dt | 500 V/µs - minimum rate-of-rise immunity at 125 °C; prevents spurious turn-on in noisy industrial environments. |
| Rth(j-h) | 5.5 K/W - thermal resistance junction-to-heatsink with compound; determines heatsink sizing for 2 A operation. |
| Visol(RMS) | 2500 V - isolation voltage between terminals and heatsink; satisfies reinforced insulation requirements per IEC 60730. |
| ITSM | 14 A - non-repetitive peak on-state current for 20 ms; supports motor startup surge currents. |
Pinout & Package
Package: TO-220F (SOT186A), plastic single-ended full-pack housing with isolated mounting base and one mounting hole. Thermally optimized for heatsink attachment; base electrically isolated from all terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Main Terminal 1 (T1) | AC line or load return path; carries full load current during conduction. |
| 2 | Main Terminal 2 (T2) | AC line or load hot path; referenced for gate triggering in QI/QII/QIII. |
| 3 | Gate (G) | Control input for triac turn-on; requires ≤10 mA pulse to trigger at 25 °C. |
| mb | Mounting Base | Electrically isolated heatsink interface; enables chassis-grounded mounting without shorting T1/T2. |
Key Features
| Feature | Design Value |
|---|---|
| 3Q triggering only | Eliminates quadrant IV sensitivity - improves EMI noise immunity in shared-control environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triac switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STMicroelectronics BTB20-800CW | 4Q triac; higher IT(RMS) = 20 A; same 800 VDRM; TO-220AB (non-isolated base). | Requires insulating washer for chassis mounting; suitable for higher-current motor drives where 4Q control is needed. | Select when full-quadrant triggering is required and heatsink isolation is managed externally. |
| ON Semiconductor MAC220A | 3Q triac; lower VDRM = 200 V; IT(RMS) = 2 A; TO-220AB; non-isolated base. | Limited to low-voltage AC systems (e.g., 24–48 VAC control circuits); not suitable for mains-connected appliances. | Choose only for low-voltage isolated control subsystems where 800 V blocking is unnecessary. |
Compared with BTB20-800CW and MAC220A, the BTA202X-800E uniquely combines 3Q noise immunity, 800 V blocking, 2 A RMS rating, and factory-isolated mounting base - making it optimal for cost-sensitive, safety-critical 230 V AC appliance designs requiring minimal external components.

FAQ
What is the maximum junction temperature specification for the BTA202X-800E?
The BTA202X-800E has a maximum junction temperature (Tj) of 125 °C, as defined in its limiting values table. This rating must be maintained through proper heatsinking - with Rth(j-h) = 5.5 K/W - to ensure reliable operation at its full 2 A RMS current rating. Exceeding 125 °C risks permanent degradation of the planar passivated structure.
Does the BTA202X-800E support four-quadrant triggering?
No, the BTA202X-800E is a three-quadrant (3Q) triac and triggers only in quadrants I (T2+, G+), II (T2+, G−), and III (T2−, G−). It does not support quadrant IV (T2−, G+) triggering - a deliberate design choice to improve noise immunity and prevent false turn-on from negative gate transients, as confirmed in Section 1 and Figure 7 of the datasheet.
Can the BTA202X-800E be used without a snubber circuit?
Yes, the BTA202X-800E is explicitly characterized for snubberless operation in inductive loads, with dIcom/dt ≥ 2 A/ms at 125 °C and 400 V under snubberless conditions (gate open circuit). This capability is validated in Table 1 and Section 4 of the datasheet, enabling simplified PCB layout for motor and solenoid control.
What is the isolation voltage rating between terminals and heatsink for the BTA202X-800E?
The BTA202X-800E provides 2500 VRMS isolation voltage (Visol(RMS)) between all main terminals (T1, T2, G) and the mounting base, tested per IEC 60730 at 50–60 Hz. This reinforced insulation rating allows direct mechanical mounting to grounded metal chassis without additional insulation hardware.
What gate trigger current range must be provided to reliably turn on the BTA202X-800E?
The BTA202X-800E requires a gate trigger current (IGT) between 0.5 mA and 10 mA at 25 °C, depending on quadrant (T2+/G+, T2+/G−, or T2−/G−), as specified in Table 1 and Table 7. At elevated temperatures (125 °C), IGT increases - design margins should target ≥5 mA to ensure robust triggering across the full –40 °C to 125 °C operating range.
