JANSR2N2484UB

The JANSR2N2484UB is a general purpose silicon NPN transistor that belongs to the family of Bipolar Junction Transistors (BJT). First introduced by Signetics in 1975, it has achieved widespread popularity since due to its characteristic high breakdown voltage, high switching speed, and its general applicability.

The device is composed of three layers - emitter, base, and collector. Under small base current, the NPN transistor acts as a circuit open switch, and under large base current, it acts as a closed switch.

Under normal usage, the JANSR2N2484UB is subjected to a base current at the input, and the transistor amplifies this base current so that a larger current of the same polarity at the output. This is known as current amplification. However, when the input current is smaller than the input resistance, the transistor then acts as a resistor to dissipate the input energy.

The JANSR2N2484UB application fields are very diverse. They are used in switching, amplifier, and as general components in instrumentation, digital logic, robotics and communications industry. They can be used as parts in digital logic gates and circuits, as current amplifiers and control devices, as linear amplifiers with feedback, and in microcontroller-based systems. In addition, they can also be used in radio frequency amplifiers, power supplies and automotive applications.

In short, the JANSR2N2484UB comes in a standard TO-220 form factor and has wide operating temperatures ranging from -65°C to 175°C. Thanks to its excellent current gain, diverse application fields and its long-term stability, the JANSR2N2484UB is one of the most popular transistors used in industry today.
