rectifier diode การใช้

• Before the development of silicon power rectifier diodes, cuprous oxide and later selenium was used.
• The circuit is similar to the one above, except that the rectifier diode is now moved into the doorbell button housing.
• It used a DC signalling system comprising a number of rectifier diodes arranged in different polarity configuration according to the button pressed.
• The rectifier diodes in an alternator automatically perform this function so that a specific relay is not required; this appreciably simplified the regulator design.
• For simple single-pole, single-throw doorbell buttons, the chime device employs a rectifier diode and ballast capacitor at the voltage input stage of the circuit.
• Popular makeshift varicaps include LEDs, 1N400X series rectifier diodes, Schottky rectifiers and various transistors used with their collector-base junctions reverse biased, particularly the 2N2222 and BC547.
• You can purchase matched rectifier diodes, which should have similar characteristics and be less prone to the problem . talk ) 08 : 16, 28 July 2012 ( UTC)
• Upon pressing the doorbell button, power is connected through the rectifier diode or series of rectifier diodes called a full wave rectifier, which allows the current to flow in only one direction, into the ballast capacitor.
• Upon pressing the doorbell button, power is connected through the rectifier diode or series of rectifier diodes called a full wave rectifier, which allows the current to flow in only one direction, into the ballast capacitor.
• Electrolytic capacitors suffer from self-degradation if unused for a period ( around a year ), and when full power is applied may short circuit, permanently damaging the capacitor and usually blowing a fuse or causing failure of rectifier diodes.
• The "'1N4001 series "'( or "'1N4000 series "') is a family of popular 1 A ( ampere ) general-purpose silicon rectifier diodes commonly used in MELF surface mount packages.
• For example, in some battery charging applications it is possible to implement a mains-powered DC power supply with nothing more than a transformer and a single rectifier diode, with a resistor in series with the output to limit charging current.
• I concluded after the fact that the " 115 VAC " shaver outlet probably just had a rectifier diode in series with the line; this would have worked with the motor of an electric razor but was death to the transformer in my charger.
• The first RMA digit thus was re-allocated from " heater power " to " p-n junction count " to form the new EIA / JEDEC " EIA-370 " standard; for example, the 1N4001 rectifier diode and packaged version.
• Reverse current / voltage behaviour is properly characterized for Zener diodes which we are not using while manufacturers of power rectifier diodes do only a pass / fail test of PIV . So they can legitimately set up a production line for 1N4007 diodes and mark them all as 1N4001, etc.
• The classic example of a non-linear load is a rectifier with a capacitor input filter, where the rectifier diode only allows current to pass to the load during the time that the applied voltage exceeds the voltage stored in the capacitor, which might be a relatively small portion of the incoming voltage cycle.
• The Philips BA 102 varicap and a common rectifier diode, the 1N5408, exhibit similar changes in junction capacitance, with the exception that the BA 102 possesses a " specified " set of characteristics in relation to junction capacitance ( whereas the 1N5408 does not ) and the " Q " of the 1N5408 is less.
