Ujt Pin Diagram. The emitter is heavily doped having many holes. When the circuit is powered the capacitor keeps pin 2 positive until the cap reaches a point and stops transferring to pin 2.
The connections at the ends of the bar are known as bases b1 and b2. For this reason the resistance between the bases is relatively high. The emitter is heavily doped having many holes.
A 47k resistor is connected from pin 6 or pin 2 to ground.
Pin 3 is connected to the base of a bc548 with a 1k resistor. The pinout details is also included in the above datasheet. R a p j l b k g h section x x v c d n n xx seating plane dim min max min max inches. It is a pulse generator with the trigger or control signal applied at the emitter.
