Applications of UJT

There are some important applications of UJT (uni-junction transistor) which are given below.

• The UJT is used in timing circuit.
• The uni-junction transistor (UJT) used as relaxation oscillator.
• It is used as voltage detector.
• The UJT is used for switching.
• It is widely used as triggering device for silicon control rectifier (SCR) and TRIAC.
• UJTs can also be used to measure magnetic flux.
• The UJT is used in phase control circuit.
• The UJT is used as saw tooth generator.
