The 2SC4420 is a kind of silicon NPN triple diffusion planar type. It is used for high breakdown voltage high-speed switching. It has the following features: (1) high-speed switching; (2) high collector to base voltage; (3) wide area of safe operation; (4) satisfactory linearity of forward current transfer ratio; (5) full-pack package which can be installed to the heat sink with one screw.
What comes next is its absolute maximum ratings at TC is 25 . (1): collector to base voltage (VCBO) is 900 V, collector to emitter voltage (VCEO) is 800 V and emitter to base voltage (VEBO) is 7 V; (2): peak collector current (ICP) is 5 A; (3): collector current (IC) is 3 A; (4): collector power dissipation (PC) is 70 W at TC is 25 and is 3 W at TA is 25 ; (5): junction temperature (Tj) is 150 ; (6): storage temperature (Tstg) is from -55 to 150 . Then is about the electrical characteristics at TC is 25 . (1): the maximum collector cutoff current (ICBO) is 50 A when VCB is 900 V and IE is 0; (2): the maximum base to emitter saturation voltage is 1.5 V at IC is 0.8 A and IB is 0.16 A; (3): the typical transition frequency is 10 MHz at VCE is 5 V, IC is 0.15 A and f is 1 MHz; (4): the typical turn-on time is 0.7 s, storage tome is 2.5 s and fall time is 0.3 s at IC is 0.8 A and VCC is 250 V.
