2SD879

JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD TO-92 Plastic-Encapsulate Transistors 2SD879 TRANSISTOR (NPN) TO-92 FEATURES z In Applications Where Two NiCd Batteries are Used to rovide 2.4V, two 2SD879s are used. z The charge time is appro ximately 1 s econd faster Than that of germanium transistors. z Less power dissip ation because o f low Collector-to-Emitter Voltage VCE(sat), permitting more flashes of light to be emitted. z Small package and large allowable collector dissipation (TO-92, PC= 750mW). z Large current capacity and highly resistant to break-down. z Excellent linearity of hFE in the region from low current to high current.
