Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits.
Note 2:
Parameters identified with
boldface type
apply at temp. extremes. All other numbers, unless noted apply at +25C.
Note 3:
Guaranteed and 100% production tested.
Note 4:
Guaranteed (but not 100% production tested) over the operating temperature and supply voltage ranges. These limits are not used to calculate outgoing
quality levels.
Note 5:
These numbers apply for pulse testing with a low duty cycle.
Note 6:
Base positive with respect to emitter.
Simplified Circuit
Applications Information
One failure mode incandescent lamps may experience is
one in which the filament resistance drops to a very low
value before it actually blows out. This is especially rough on
most solid-state lamp drivers and in most cases a lamp fail-
ure of this type will also cause the lamp driver to fail. Be-
cause of its high gain and blowout-proof design, the LP395 is
an ideal candidate for reliably driving small incandescent
lamps. Additionally, the current limiting characteristics of the
LP395 are advantageous as it serves to limit the cold fila-
ment inrush current, thus increasing lamp life.
