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.
