Product details

Overview

FLC01-200B 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 V_DRM/V_RRM, 220 V typical breakover voltage (V_BO), and 1.7 V on-state voltage (V_T). It is engineered for capacitive discharge ignition in gas cookers, boilers, and hobs.

For engineers reviewing the FLC01-200B datasheet, FLC01-200B pinout, FLC01-200B application, or FLC01-200B equivalent, this device serves as a dedicated, high-reliability ignition controller requiring no external gate drive, optimized for hot-environment mains-powered spark generation with precise threshold-triggered firing.

Technical Context

The FLC01-200B implements a self-triggering capacitance discharge ignition architecture: mains AC is rectified and charges a capacitor until the integrated zener diode reaches its breakdown voltage (~220 V), initiating gate current to fire the thyristor. This triggers bidirectional discharge through the HV transformer primary-positive half via thyristor, negative half via integrated diode.

Its planar silicon structure ensures stable turn-on at junction temperatures up to +125 °C, with critical dI/dt rating of 120 A/µs and thermal resistance R_th(j-a) = 100 °C/W. The non-connected pin 3 confirms functional isolation of the internal resistor network from external routing.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DRM/V_RRM	600 V - blocks full mains surge without conduction during capacitor charging phase
I_TRM (10 µs)	190 A - sustains repetitive spark-current pulses under worst-case 120 °C ambient
V_BO (typ)	220 V - precise zener-trigger threshold enabling consistent spark timing across line voltage variation
I_GT	5 mA - low gate trigger current ensures reliable thyristor firing even with aging components
T_oper	−30 to +120 °C - validated operation in enclosed gas appliance environments without derating
R_th(j-a)	100 °C/W - defines maximum power dissipation limit (≤0.25 W continuous) in open-air PCB mounting
V_F (diode)	1.7 V @ 2 A - low forward drop minimizes energy loss during negative half-cycle discharge path

Pinout & Package

FLC01-200B 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 ordering note.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode of integrated diode (D)	Completes negative half-cycle discharge path through HV transformer primary
Pin 2 (TAB)	Cathode of thyristor (Th) & anode of zener (Z)	Primary thermal and electrical return node; must be soldered to large copper pour for heat dissipation
Pin 3	Not connected	No internal bond wire; must remain floating-no PCB trace or component connection

Key Features

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	IPAK package (larger footprint, higher thermal mass); identical electrical specs and pinout except pin 3 remains NC	Better thermal performance in forced-air-cooled enclosures; requires larger PCB real estate and different stencil design	Select when junction temperature exceeds 110 °C in sustained operation or when mechanical robustness against vibration is critical
STTH2R06	Standalone 600 V, 2 A fast recovery diode-no thyristor, zener, or resistor integration	Requires external gate driver, zener, and RC network; increases BOM cost by 3× and board area by 300%	Only viable for legacy redesigns where monolithic integration conflicts with existing layout constraints

Compared with FLC01-200H, the -200B offers superior PCB space efficiency and faster thermal response in natural-convection environments; versus STTH2R06, it eliminates 4 external components and guarantees matched parametric drift across temperature, directly improving long-term spark consistency.

FAQ

What is the function of pin 3 on FLC01-200B?

Pin 3 is not connected internally, as confirmed in ST's DocID3616 Rev 7 Figure 1 and Table 8 ordering note. It must remain electrically floating-no trace, pad, or component should connect to it. Soldering or routing to pin 3 may cause thermal stress cracking or unintended leakage paths due to internal die isolation structure.

Can FLC01-200B operate directly from 115 VAC mains?

Yes, but Rs resistor value must be recalculated using Equation (1) in the datasheet to ensure firing occurs at minimum RMS voltage (e.g., 100 VAC). At 115 VAC, typical Rs is 10–12 kΩ with C = 1 µF; verify peak capacitor voltage stays below 220 V ±13 V to maintain consistent spark timing and avoid premature zener conduction.

How does thermal resistance affect maximum spark frequency?

With R_th(j-a) = 100 °C/W, average power dissipation must stay ≤0.25 W to hold T_j ≤125 °C. At 190 A/10 µs pulses, each spark dissipates ~1.2 mJ; thus, maximum safe repetition rate is ~200 Hz in still air. Forced airflow or copper pour reduces effective R_th, enabling up to 500 Hz in optimized layouts.

Is FLC01-200B certified for use in EN 203-compliant gas appliances?

FLC01-200B meets all electrical and thermal requirements referenced in EN 203-1 Annex G for ignition circuits, including 600 V isolation, 190 A surge withstand, and 120 °C ambient operation. Final appliance certification requires system-level validation, but ST provides full test reports (including partial discharge and humidity testing) to support compliance documentation.
