The 2SB09490Q is an NPN bipolar junction transistor (BJT) used in many electronic applications. It is typically used to amplify or switch signals in circuits like radio receivers and television sets. This type of transistor has two terminals and is mainly used for switching and amplifying electrical signals.

The 2SB09490Q has a collector-base breakdown voltage of 80V, a collector-emitter breakdown voltage of 45V and an emitter-base breakdown voltage of 5V. It is capable of handling a maximum current of 0.15 amperes, and has a power dissipation of 0.25 watts. It features forward current gain over a wide frequency range, from dc to high frequencies, with a minimum current gain of 15. The device also has a wide temperature range, from -55 degrees Celsius to +150 degrees Celsius, and a storage temperature ranging from -65 degrees Celsius to +150 degrees Celsius.

The 2SB09490Q transistor works by transmitting current through the base and emitter terminals. The emitter-base junction is forward biased, meaning it accepts and sends electrical current. This allows the current to be transferred to the collector and out of the device. The current gain of the device is determined by the ratio of base-collector current to the base-emitter current. A higher current gain is achieved when the base current is low. This allows the current through the device to be amplified. The current gain of the device can be adjusted by changing the value of the base current.

The 2SB09490Q can be used in a variety of applications, such as amplifier circuits, logic circuits and power supplies. It can be used as an amplifier for radio and TV receivers, as well as for common audio systems. It can also be used as a switch in small appliances, such as fans and kitchen appliances. The transistor can also be used in linear voltage regulators and current source circuits.

The 2SB09490Q is a versatile transistor and can be used in many circuits. Its wide frequency range and high current gain makes it suitable for many applications, and its high temperature range makes it suitable for use in high-temperature environments. The device is also very reliable and is able to operate reliably in harsh conditions. It is an ideal choice for many different applications.
