2N5089 NPN Transistor : Pin Configuration & Its Applications

• 2N5089 NPN TRANSISTOR is used for low-level, low-noise amplifier applications.

Pin Configuration

• Pin 1 – Emitter(emits all the free charges).
• Pin 2 – base (transfers all the charges from emitter to collector without/minimum loss).
• Pin 3 – Collector(collects all the charge carriers) produces collector current Ic.

Voltages:

• Collector to Emitter Voltage VCEO = 25 Vdc
• Collector to Base Voltage VCBO = 30 Vdc
• Emitter to Base Voltage VEBO = 3.0 Vdc

Transfer Parameters:

• hFE – Min hFE = 400 (when, IC = 100 Ampdc, VCE = 5.0 Vdc
  Max hFE = 1200 (when, IC = 100 Ampdc, VCE = 5.0 Vdc)

Gain:

• Current-gain-bandwidth Product = 50 Mhz
  (IC = 500 Adc, VCE = 5.0 Vdc, f = 20 MHz)
  Small−Signal Current Gain = 450(min), 1800(max)

Applications of 2N5089 NPN Transistor

• As a switch

• As a low gain amplifier with noise cutoff.

• Push-pull circuits, sensor circuits, low gain amplifiers.
