Product details
Overview
FLC01-200B-TR from STMicroelectronics is a monolithic fire lighter circuit integrating a thyristor, zener diode, rectifier diode, and 2 kΩ resistor in a single DPAK package. It delivers 190 A pulse current (tp = 10 µs), operates up to +120 °C ambient, and features 600 V VDRM/VRRM for capacitance discharge ignition in gas cookers and boilers.
For engineers reviewing the FLC01-200B-TR datasheet, FLC01-200B-TR pinout, FLC01-200B-TR application, or FLC01-200B-TR equivalent, this page provides verified functional architecture, thermal limits, breakover voltage tolerance (206–233 V), gate trigger current (5 mA), and DPAK mechanical dimensions per DocID3616 Rev 7.
Technical Context
The FLC01-200B-TR implements a self-triggering capacitance discharge ignition topology: mains AC charges capacitor C via external rectifier Ds; when voltage reaches zener threshold (VBO = 206–233 V), current flows into thyristor gate, firing it to discharge C through HV transformer primary.
Its planar silicon structure supports repetitive 190 A surge pulses at 120 °C junction temperature, with critical di/dt rating of 120 A/µs and thermal resistance Rth(j-a) = 100 °C/W - enabling reliable operation in sealed, high-temperature appliance enclosures without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(rms) | 4 A RMS current handling capability for continuous conduction mode in ignition control circuits |
| VDRM / VRRM | 600 V maximum blocking voltage - ensures safe operation across 230 VAC mains with margin against transients |
| IGT | 5 mA gate trigger current - enables low-power zener-based triggering without auxiliary driver circuitry |
| ITRM (tp = 10 µs) | 190 A peak repetitive surge current - sustains spark energy delivery over product lifetime in gas ignitors |
| Toper | −30 °C to +120 °C operating range - validated for embedded use inside hot appliance housings (e.g., gas boiler combustion chambers) |
| Rth(j-a) | 100 °C/W junction-to-ambient thermal resistance - defines maximum power dissipation (≤0.36 W at 120 °C ambient) without heatsink |
Pinout & Package
FLC01-200B-TR uses the DPAK (TO-252) surface-mount package with exposed thermal tab (pin 2). Pin 3 is internally unconnected per datasheet Figure 1 and Table 8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of integrated diode (D) | Connects to capacitor negative terminal and HV transformer primary return path during negative half-cycle discharge |
| Pin 2 | Cathode of thyristor (Th) & Anode of zener (Z) & Thermal tab | Main current return path; electrically common node for switching, threshold sensing, and heat dissipation |
| Pin 3 | No internal connection | Must be left floating - no routing or soldering required; confirmed unconnected in functional diagram and ordering table |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated thyristor-diode-zener-resistor integration | Reduces BOM count by 4 discrete components and eliminates layout sensitivity in spark timing circuits |
| 190 A pulse current capability (tp = 10 µs) | Enables consistent spark generation across >100,000 ignition cycles under worst-case mains voltage and temperature |
| Breakover voltage tolerance (206–233 V) | Guarantees reliable firing across production lot variation and aging drift without recalibration |
| Planar silicon technology | Delivers stable leakage current (<10 µA at 125 °C) and avoids parameter shift in humid, high-temp environments |
| Lead-free DPAK package | Meets RoHS and UL94 V0 flammability requirements for direct mounting on appliance PCBs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitance discharge ignition applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FLC01-200H | Same die, IPAK package with larger thermal pad (L = 9.6 mm vs DPAK's 1.78 mm); Rth(j-a) ≈ 75 °C/W | Better thermal performance in forced-air or heatsink-mounted designs; higher mechanical torque tolerance (0.4–0.6 N·m) | Select when board space allows larger footprint and thermal management requires <100 °C/W Rth(j-a) |
| STTH1L06 | Standalone 600 V, 1 A fast recovery diode - lacks thyristor, zener, and resistor integration | Requires external SCR, zener, and gate resistor; increases component count and layout complexity | Only viable if redesign permits discrete implementation and cost sensitivity outweighs reliability/size benefits |
Compared with FLC01-200H, the -200B-TR offers smaller DPAK footprint and tape-and-reel packaging for automated SMT assembly, while STTH1L06 demands full external circuit design and forfeits monolithic timing precision and thermal robustness.

FAQ
What is the function of pin 3 on FLC01-200B-TR?
Pin 3 is internally unconnected per STMicroelectronics DocID3616 Rev 7 Figure 1 and Table 8. It must remain floating - no electrical connection or soldering is permitted. This is a structural pin in the DPAK mold compound, not an active terminal.
Can FLC01-200B-TR operate directly from 115 VAC mains?
Yes, but requires recalculation of Rs and C values per Equation (1) in the datasheet. At 115 VAC RMS, the maximum Rs must be reduced to ensure firing occurs even at minimum line voltage and maximum VBO (233 V), maintaining reliable spark generation across voltage tolerances.
How does temperature affect breakover voltage stability?
VBO varies linearly with junction temperature at αT = 0.27 V/°C (Table 5). From 25 °C to 125 °C, VBO shifts +27 V - fully characterized and accounted for in the 206–233 V min/max specification. No external compensation is needed for stable operation.
Is FLC01-200B-TR qualified for automotive use?
No. ST explicitly states in DocID3616 Rev 7 page 11 that its products "are not designed or authorized for use in automotive applications or environments." The FLC01 series targets domestic/commercial gas appliances only, with no AEC-Q100 qualification or automotive-grade screening.
