The Datasheet BD140 unveils the characteristics of a popular PNP bipolar junction transistor (BJT). It’s a crucial resource for electronics hobbyists, students, and professionals who design and build circuits. Understanding the specifications outlined in the Datasheet BD140 allows users to effectively incorporate the transistor into various applications.
Understanding the BD140 Transistor
The Datasheet BD140 details a general-purpose PNP transistor, meaning it controls current flow between the collector and emitter terminals based on the current applied to its base. Think of it like a switch, but instead of flipping a lever, a small current at the base controls a larger current flowing through the other two terminals. These transistors are commonly used for amplification or switching purposes in electronic circuits. Understanding its parameters is fundamental for successfully implementing the BD140 into your projects.
The data sheet provides crucial parameters which can be highlighted as follows:
- VCEO: Collector-Emitter Voltage (Maximum).
- IC: Collector Current (Maximum).
- PD: Total Device Dissipation.
- hFE: DC Current Gain (β). This parameter is super important for amplification application.
BD140 is usually selected when it can meet certain design requirements. Applications include:
- Audio Amplifiers: Used in pre-amplifiers or output stages for sound amplification.
- Switching Circuits: To control LEDs, relays, or other components based on a control signal.
- Linear Regulators: For maintaining a stable voltage output.
| Parameter | Typical Value |
|---|---|
| Vceo (V) | -80 |
| Ic (A) | -1.5 |
| hFE | 40-160 |
When implementing this transistor, you should keep in mind the maximum voltage rating, maxium collector current, and power dissipation limitations as defined in the datasheet. Exceeding these limits can damage the component, rendering it useless. Always use the Datasheet BD140 to guarantee your design operates inside the safe operating area for your circuit.
