UJT Transistors

UJT (Unijunction Transistor) transistors are essential semiconductor devices widely utilised in various electronic applications for their unique characteristics and capabilities. Made primarily from silicon, UJTs exhibit distinct features that differentiate them from conventional bipolar junction transistors (BJTs). These devices are mainly available in two types: standard and programmable UJTs, each tailored to specific functions. UJTs are known for their ability to handle high voltage and current levels, making them perfect for applications requiring precise timing and triggering. Their low power consumption and compact design enhance their utility in various circuits, particularly in oscillators, pulse generators, and timing devices.
