What the Fire Lighting Circuit does on a board
The FLC01-200B-TR is a Fire Lighting Circuit from STMicroelectronics, a discrete semiconductor that provides ignition control in gas burner systems, ovens, and industrial flame-safeguard controllers. It sits in the Discrete Semiconductors category and delivers a controlled spark sequence when the control loop calls for ignition. Packaged in a DPAK (TO-252-3) with a surface-mount footprint, this part is designed for automated assembly on reflow lines. The exposed tab on the DPAK carries the thermal path to the PCB copper pour — a solid thermal connection under the tab keeps the junction temperature within limits during repeated ignition cycles.
The part is ROHS3 Compliant, so it meets the European RoHS directive without exemptions — no lead, mercury, cadmium, or restricted phthalates in the package or die attach.
Sourcing and supply posture
The tape-and-reel packaging (Cut Tape also available) suits both prototype builds and production reels. The DPAK footprint is common across ST's discrete line, so the same solder paste stencil and pick-and-place nozzle work for this part and other TO-252 devices on the same board.
