FUNCTIONAL DIAGRAM DESCRIPTION The FLC21 series have been developed especially for capacitance discharge operation. The main applications are: fuel ignitor, fuel or gas heater, gas range, cook top, barbecue, water heater, HVAC, portable ignitor, insect killers. It uses a high performance planar diffused technology device adapted to high temperature in rugged environmental conditions. The typical supply of the FLC21 fire lighter circuit is a DC battery or the AC mains. Th: Thyristor for the switching operation. Z: Zener diode to set the igniting threshold voltage. D: Diode for the reverse conduction. R: 2 kΩ resistor. DEVICE TYPE FLC21-135A FLC21-65A
