TN22_05 Datasheet, PDF (1/9 Pages) STMicroelectronics – STARTLIGHT

®
FEATURES AND BENEFITS
■ High clamping voltage structure (1200 -1500V)
■ Low gate triggering current for direct drive from
line (< 1.5mA)
■ High holding current (> 175mA), ensuring high
striking energy.
DESCRIPTION
The TN22 has been specifically developed for use
in electronic starter circuits. Use in conjunction
with a sensitive SCR and a resistor, it provides
high energy striking characteristics with low trig-
gering power. Thanks to its electronic concept, this
TN22 based starter offers high reliability levels and
extended life time of the fluorescent tubelamps.
