Ordering number:EN550F
NPN Epitaxial Planar Silicon Transistor
2SD879
1.5V, 3V Strobe Applications
Features
· In applications where two NiCd batteries are used to provide 2.4V, two 2SD879s are used.
· The charge time is approximately 1 second faster than that of germanium transistors.
· Less power dissipation because of low Collector-toEmitter Voltage VCE(sat), permitting more flashes of light to be emitted.
· Small package and large allowable collector dissipation (TO-92, PC=750mW).
· Large current capacity and highly resistant to breakdown.
· Excellent linearity of hFE in the region from low current to high current.
