Product details
Overview
FLC10-200H from STMicroelectronics is a monolithic fire lighter circuit integrating a thyristor, zener diode, diode, and 2 kΩ resistor in a single IPAK package. It delivers 240 A pulse current (tp = 10 µs), operates up to +120 °C ambient, and provides capacitance discharge ignition for gas cookers, boilers, and hobs.
For engineers reviewing the FLC10-200H datasheet, FLC10-200H pinout, FLC10-200H application, or FLC10-200H equivalent, key selection criteria include breakover voltage (200–250 V), peak surge current capability, thermal resistance (Rth(j-a) = 100 °C/W), and high-temperature reliability in flame ignition systems.
Technical Context
The FLC10-200H implements a self-triggering capacitance discharge ignition topology: mains AC is rectified, charges a capacitor via Ds, and fires the integrated thyristor when the zener (VBO = 200–250 V) reaches breakdown, initiating HV spark generation.
Its planar silicon structure enables fast turn-on, high dl/dt tolerance (200 A/µs), and stable operation across −30 °C to +120 °C ambient. The integrated 2 kΩ resistor sets gate sensitivity and works with external Rs/C to control spark frequency and ensure firing under worst-case low-VAC conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakover Voltage (VBO) | 200–250 V at 25 °C - defines capacitor charge threshold for reliable thyristor triggering |
| Peak Surge Current (ITRM) | 240 A (tp = 10 µs, Tamb ≤ 120 °C) - sustains repetitive HV spark pulses without degradation |
| Thermal Resistance (Rth(j-a)) | 100 °C/W (IPAK) - determines junction temperature rise under pulsed load in enclosed ignitor housings |
| Operating Temperature | −30 °C to +120 °C - validated for mounting near gas burners and in unventilated appliance enclosures |
| Integrated Resistor | 2 kΩ - provides fixed gate bias path, eliminating external component for basic ignition circuits |
| Diode Forward Voltage (VF) | ≤1.7 V at IF = 2 A - minimizes conduction loss during negative half-cycle capacitor discharge |
Pinout & Package
FLC10-200H uses the IPAK (TO-251AA) package with exposed metal tab for thermal dissipation and electrical connection. Pin 1 and Pin 3 are internally shorted and must be externally connected together in PCB layout; Pin 2 (and tab) serves as common cathode/anode return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 / Pin 3 (shorted) | Anode of thyristor & cathode of zener | Primary high-voltage input node - connects to charged capacitor and zener anode |
| Pin 2 / Tab | Cathode of thyristor & anode of diode | Common return path - ties thyristor cathode, diode anode, and heatsink ground |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated thyristor-diode-zener-resistor integration | Reduces BOM count by 4 discrete components and eliminates layout-sensitive gate drive routing |
| 240 A pulse current rating | Enables robust spark generation across 50–60 Hz mains cycles without derating at 120 °C ambient |
| Planar silicon technology | Ensures long-term reliability under thermal cycling in gas appliance environments |
| UL94 V0 epoxy package | Meets flammability requirements for internal placement in consumer gas equipment housings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar capacitance discharge ignition applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FLC10-200B | DPAK package (Rth(j-a) = 70 °C/W @ S = 0.5 cm²), 0.3 g weight, tape-and-reel packaging | Better thermal performance on small PCB pads; lower mass suits vibration-prone installations | Select for space-constrained designs requiring higher power density and automated assembly |
| STF10N65M2 | Standalone 650 V N-channel MOSFET (no integrated zener/diode/resistor); requires external trigger network | Greater design flexibility but increases component count, layout complexity, and validation effort | Select only when custom timing, adjustable VBO, or multi-stage discharge control is required |
Compared with FLC10-200B, the FLC10-200H offers superior mechanical robustness and higher torque tolerance (0.4–0.6 N·m) for screw-mount applications, while STF10N65M2 shifts system-level responsibility to the designer for gate drive, protection, and thermal management - increasing time-to-market and qualification burden.

FAQ
What is the function of the integrated 2 kΩ resistor in FLC10-200H?
The integrated 2 kΩ resistor provides a fixed gate current path from the zener diode to the thyristor gate. It ensures reliable triggering even under minimum mains voltage conditions by setting a defined gate sensitivity threshold, eliminating the need for an external resistor in basic ignition circuits.
Can FLC10-200H operate directly from 110 V AC mains?
Yes - the FLC10-200H's breakover voltage range (200–250 V) and internal Rs/C design methodology support both 110 V and 220 V AC mains. For 110 V systems, external Rs must be reduced (per Equation 1 in datasheet) to maintain sufficient gate current at lower peak capacitor voltage.
Is the metal tab electrically isolated in FLC10-200H?
No - the metal tab is electrically connected to Pin 2 and serves as the common cathode/anode return terminal. It must be mounted to a grounded or referenced heatsink; isolation requires insulating hardware and dielectric thermal interface material per ST's mounting recommendations.
How does FLC10-200H handle repeated spark events in rapid succession?
It supports repetitive operation at up to 3 Hz (per Figure 6) with appropriate Rs/C selection. Thermal limits are governed by Rth(j-a) = 100 °C/W and average power dissipation equations for thyristor and diode - sustained >5 Hz requires forced cooling or derating per Figure 8's ITRM vs. tp curve.
