UJT Relaxation Oscillator 


  • Study of zener diode as voltage regulator.
  • Study of static emitter characteristics of UJT- uni-junction transistor on oscilloscope.
  • Study of effect of V on peak point and valley point voltage and valley point current.
  • Operation of UJT relaxation oscillator and its use as SCR trigger circuit.
  • Control of UJT trigger pulses with shunt transistor.
  • Study of variations in gate resistance & capacitance, resistance of source & drain and their effect on trigger pulse characteristics of UJT relaxation oscillator.
  • Various configurations of UJT relaxation oscillator type 1(low output impedance), type 2 (moderate output impedance) and type 3 (high output impedance).

In built parts:

  • An isolation transformer 230 V A.C. At 100 mA.
  • This protects external instruments from damage if they are not isolated.
  • 20V D.C. at 100mA, IC regulated power supply internally connected.
  • Bridge rectifier and zener regulator.
  • Potentiometer for frequency control.
  • Two band switches for selecting different value of resistance and capacitance.
  • Pulse transformer 1:1:1.
  • UJT 2N 2646 under experiment.
  • Adequate no. of other electronic components.
  • Mains ON/OFF switch, fuse and jewel light.


  • The unit is operative on 230 V ±10% at 50 Hz A.C. mains.
  • Adequate no. of patch cords stackable 4 mm spring loaded plug length ½ meter.
  • Good quality, reliable terminal/sockets are provided at appropriate places on panel for connections/observation of waveforms.
  • Strongly supported by detailed operating instructions, giving details of object theory, design procedures, report suggestions and book references.


  • 3 kg. (approx.)


  • W 340 x H 110 x D 210

Other apparatus required:
