  • Technical Article: Bipolar Transistor Tutorial

    Bipolar transistors, having 2 junctions, are 3 terminal semiconductor devices. The three terminals are emitter, collector, and base. A transistor can be either NPN or PNP. See the schematic... American Micro Semiconductor -- Semiconductor Tutorials. Home. Online Store. Diodes. Transistors

  • Transistor-Transistor Logic (TTL)

    Transistor-transistor logic (TTL) is a class of digital circuits built from bipolar junction transistors (BJT), diodes and resistors. It is notable, as it was the base for the first widespread semiconductor integrated circuit (IC) technology. All TTL circuits operate with a 5 V power supply. TTL

  • JFET Application Note: Reset Transistor

    In JFETs designed primarily for silicon drift detectors and Si(Li) detectors,. the reset transistor is configured as shown in Figure 1, with the base. shorted to the source, the collector shorted to the gate, and the emitter. connected to the reset pad. Since the gate-source JFET junction

  • Bipolar Junction Transistors

    transistors come in a wide variety of physical packages. Package type is primarily dependent upon the power dissipation of the transistor, much like resistors: the greater the maximum power dissipation, the larger the device has to be to stay cool. There are several standardized package types

  • Re: Baldwin Model 4 Church Organ

    GA But, those circuit diagrams are full of transistors so, this may not be the manual for DCaD's organ.

  • Re: 555 timer to control motors

    Keep them coming, I love this sort of thing! This sounds like you have the motor connected to the timing inputs rather than the output of the 555. 1. How are you using the 2N3055 to drive the motor? 2. Can you post a diagram of the circuit you used? 3. Do you know how much cu...

  • Consistent Blown Fuses

    CONSISTENT BLOWN FUSES I am tasked to repair a PCB card for an old transducer box without the schematic diagram. Problem: The fast blow 1A fuse in the card keeps blowing off. After tracing part of the circuitry on the card, I deduced that it was a power supply card with two dc outputs,...

  • Re: how to check pcb

    Guest Like Del pointed out , it is indeed patience testing workout , it is ahuge task and to the best satisfying if you make it to work . you gota know circuit diagrams for transistors , mosfets , diodes and other components with there specs , have acircuit diagram at hand , make primary obes...

  • Re: Favourite constructional toys

    Out of the construction toys.... I reckon the early ones were Lego then Meccano, but my favourite was Philips Electronic Engineer kit with the then new transistors in it (OC71)... It had a bread board style and you fitted the template showing the circuit diagram to it using binding posts, so...

  • Re: DC control systems and polarity

    Its only a standard because engineers draw the circuit that way now... its not 'illegal' to draw a positive earthed circuit with the negative at the top of the drawing, in fact it makes perfect sense to do so. As I said when transistors first came out they were mostly PNP devices and so the p...

Bipolar Junction Transistor (BJT)

Description of bipolar transistor. The transistor is primarily used as a current amplifier. When a small current signal is applied to the base terminal of a bipolar transistor, it is amplified in the collector circuit. This current amplification is referred to as hfe or beta and equals Ic/Ib. As with all semiconductors, breakdown voltage of a transistor is also a design limitation. There are breakdown voltages that must be taken into account for each combination of terminals of a transistor...
