Datasheet C3198 refers to the specifications document for the 2SC3198 NPN silicon epitaxial transistor. This datasheet provides crucial information regarding the electrical characteristics, performance parameters, and application guidelines for this particular transistor. It is an essential resource for engineers, hobbyists, and anyone involved in electronics design and repair who intends to use this component.
Understanding the 2SC3198 Transistor and Its Applications
The 2SC3198 is a widely used NPN transistor known for its good amplification capabilities and relatively low noise. It’s often found in audio amplifiers, switching circuits, and general-purpose amplification stages. The datasheet details important parameters such as voltage ratings (collector-emitter, collector-base, emitter-base), current ratings (collector current, base current), and power dissipation limits. These parameters are critical for ensuring the transistor operates within its safe operating area and avoids damage. Understanding these limits is paramount for reliable circuit design. Here are some of the parameters detailed in the datasheet:
- Collector-Emitter Voltage (Vceo): This specifies the maximum voltage that can be applied between the collector and emitter without causing breakdown.
- Collector Current (Ic): This specifies the maximum continuous current that can flow through the collector.
- Power Dissipation (Pd): This specifies the maximum amount of power the transistor can dissipate as heat. Exceeding this limit can lead to overheating and failure.
Datasheet C3198 also offers information about the transistor’s electrical characteristics, such as its current gain (hFE), saturation voltages, and cutoff frequencies. The current gain (hFE) is a measure of the transistor’s amplification capability - how much the collector current increases for a given increase in base current. These characteristics help designers predict the transistor’s behavior in different circuit configurations and optimize its performance. Consider a simple example:
- You want to design an amplifier with a specific gain.
- Consult the datasheet to find the hFE range for the 2SC3198.
- Choose biasing resistors that will provide the desired operating point and achieve the target gain, considering the typical hFE value.
Furthermore, Datasheet C3198 provides information about the transistor’s physical characteristics, such as its package type and pinout configuration. This helps designers properly mount the transistor on a circuit board and connect it to other components. A typical datasheet will provide dimensional drawings and terminal assignments. A simplified example can be represented as follows:
