概要

Description

The BC817 is a popular NPN bipolar junction transistor (BJT) used in various electronic applications, particularly in amplification and switching. It is commonly used in low-power applications due to its compact size and efficient performance. The BC817 typically comes in a SOT-23 package, making it suitable for surface-mount technology (SMT) applications.
Key features of the BC817 include its maximum collector current of 500 mA and a collector-emitter voltage of up to 45 V. It has a DC current gain (hFE) ranging from 100 to 630, which makes it suitable for use as a general-purpose amplifier. Additionally, the transistor operates effectively at frequencies up to several tens of MHz.
The BC817 is widely used in consumer electronics, automotive applications, and other circuits requiring small signal amplification or switching. Its reliability, availability, and cost-effectiveness make it a preferred choice for designers and engineers working on compact electronic devices.

3. Collector Current (Ic): The maximum continuous collector current is 500 mA, enabling it to drive moderate loads.
4. DC Current Gain (hFE): The transistor offers a high DC current gain ranging from 100 to 630, which varies according to specific versions (BC817-16, BC817-25, BC817-40).
5. Transition Frequency (fT): It typically has a high transition frequency of about 100 MHz, suitable for high-frequency applications.
6. Power Dissipation: The device can dissipate up to 250 mW of power at 25°C ambient temperature.
These features make the BC817 suitable for a variety of low to medium power applications in both analog and digital circuits.

Pinout

The BC817 is a NPN bipolar junction transistor (BJT) commonly used in electronic circuits for switching and amplification purposes. It comes in a SOT-23 package, which is a small surface-mount technology package. The BC817 has three pins:
1. Pin 1 (Base): This is the control pin for the transistor. A small current injected into the base allows for a larger current to flow from the collector to the emitter.
2. Pin 2 (Emitter): The emitter is the pin through which current leaves the transistor. In an NPN transistor like the BC817, the emitter emits electrons into the base region.
3. Pin 3 (Collector): The collector is the pin through which current enters the transistor. It collects carriers from the base and emitter regions.
These pin configurations are typical for BJTs and are essential for its function as a switch or an amplifier in various applications.
