The S6521BF is a two-terminal, low-leakage bipolar transistor that can handle continuous currents of up to 30mA. It is constructed with a NPN architecture and has an emitter-base voltage rating of 30V. The S6521BF features a collector-emitter saturation voltage of 0.35V, a low base-emitter saturation voltage of 0.9V, and a base-emitter leak current of 5μA. This device has a maximum collector-emitter voltage rating of 80V and it has a maximum power dissipation of 250mW. In addition to this, the S6521BF has a low on-state resistance of 90Ω.

The S6521BF has various applications. It can be used as a switching transistor in power supplies and variable frequency drives. It can also be used in medical equipment and industrial motor control systems. Additionally, the S6521BF can be used as a driver in audio amplifiers and relatively high frequency amplifiers. It can also be used in motor control circuits, clock circuits, and other timing circuits.

Regarding the working principle of the S6521BF, we can say that when it is in the off-state, the base-emitter junction of the transistor is reverse-biased. This means that the base-emitter loop is disconnected and no current flows between the collector and the emitter. However, when the transistor is switched on, current starts flowing through the base-emitter junction and the collector-base junction is forward-biased. This causes current to flow through the collector and emitter of the device. When this occurs, the base current also increases, and this further increases the current flowing through the transistor.

In conclusion, the S6521BF is a semiconductor device that is used in various applications such as power supplies, variable frequency drives, medical equipment, and industrial motor control systems. This device has a maximum collector-emitter voltage rating of 80V and it has a maximum power dissipation of 250mW. Working principle wise, when it is switched on, current starts flowing through the base-emitter junction and the collector-base junction is forward-biased, allowing current to flow through the collector and emitter of the device.
