2SC4574

The 2SC4574 is designed as one kind of medium power transistor (motor, relay or solenoid drive) (60+/-10 V, 4 A) that has four points of features:(1)built-in zener diode between collector and base;(2)storage protection against reverse surges due to "L" loads;(3)built-in resistor between base and emitter;(4)built-in damper diode. The absolute maximum ratings of the 2SC4574 can be summarized as:(1)collector-base voltage: 60+/-10 V;(2)collector-emitter voltage: 60+/-10 V;(3)emitter-base voltage: 6 V;(4)collector current: 4 A or 6 A;(4)junction temperature:150;(5)storage temperature:-55 to +150.

And the electrical characteristics of the 2SC4574 can be summarized as:(1)collector-base breakdown voltage: 50 to 70 V;(2)collector-emitter breakdown voltage: 50 to 70 V;(3)emitter cutoff current: 3 mA;(4)collector-emitter saturation voltage: 1.5 V;(5)DC current transfer ratio: 2000 to 10000;(6)transition frequency: 80 MHz;(7)output capacitance: 30 pF.
