MJE243 - NPN,
MJE253 - PNP
Complementary Silicon
Power Plastic Transistors
These devices are designed for low power audio amplifier and
low−current, high−speed switching applications.
Features
• High Collector−Emitter Sustaining Voltage −
VCEO(sus) = 100 Vdc (Min)
• High DC Current Gain @ IC = 200 mAdc
hFE = 40 −200
= 40 −120
• Low Collector−Emitter Saturation Voltage −
VCE(sat) = 0.3 Vdc (Max) @ IC = 500 mAdc
• High Current Gain Bandwidth Product −
fT = 40 MHz (Min) @ IC = 100 mAdc
• Annular Construction for Low Leakages
ICBO = 100 nAdc (Max) @ Rated VCB
• Pb−Free Packages are Available*

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
