The C4204 is 25V, 0.7A, NPN Epitaxial Planar Silicon Transistor. A NPN transistor is a type of bipolar junction transistor (BJT) that consists of two n-type semiconductor materials separated by a single p-type material.

Characteristics of NPN Transistors

1. Bipolar Junction: NPN transistors are bipolar junction transistors (BJT), meaning they have a structure consisting of three regions of alternating P-type and N-type semiconductors.

2. Current Amplification: NPN transistors are designed to amplify electrical current, and can be used in a wide range of electronic applications such as amplifiers, switches, and oscillators.

3. Forward Biased: In order to operate, the base-emitter junction of an NPN transistor must be forward biased, meaning that the base must be connected to a positive voltage relative to the emitter.

4. High Input Impedance: NPN transistors have a high input impedance, which means that they are less likely to draw current from the input source, and are therefore less likely to cause a drop in voltage across the source.


1. Adoption of MBIT process.
2. High DC current gain (hFE=800 to 3200).
3. Large current capacity (IC=0.7A).
4. Low collector-to-emitter saturation voltage (V CE(sat)≤0.5V).
5. High VEBO(VEBO≥15V)


1. AF amplifier, various drivers
