Silicon Diodes Manufacturer are electronic components that conduct current in only one direction.  In function, they are similar to one-way valves. Silicon Diodes Manufacturer using semiconductor materials such as silicon, germanium or selenium and are used as voltage regulators, signal rectifiers, oscillators and signal modulators / demodulators. Semiconductor diodes consist of a PN junction having two terminals, an anode (+) and a cathode (-). Current flows from the anode to the cathode within the diode .  Diodes can be used as voltage regulators, tuning devices in RF tuned circuits, frequency multiplying devices in RF circuits, mixers in RF circuits, switching applications, or can be used to make logic decisions in digital circuits. Diodes can be sub-divided into six major categories: General purpose diodes Manufacturer (or PN junction diodes) PIN diodes manufacturer Schottky barrier diodes manufacturer Step-recovery diodes manufacturer Varactor diodes manufacturer Zener diodes manufacturer PIN diodes Manufacturer are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies. This resistance typically ranges from kilo ohms to less than 1 ohm for a given diode. PIN diodes are typically used as switches or attenuator elements Step-recovery diodes employ graded doping where the doping level of the semi conductive materials is reduced as the PN junction is approached. This produces an abrupt turn-off time by allowing a very fast release of stored charge when switching from forward to reverse bias. It also allows a rapid re-establishment of forward current when switching from reverse to forward bias. These diodes are used in very high frequency (VHF) and fast switching applications. Varactor diodes are p-n junction diodes that are designed to act as a voltage-controlled capacitance when operated under reverse bias. One characteristic of PN junctions is inherent capacitance. When the junction is reverse biased, increasing the applied voltage will cause the depletion region to widen, thus increasing the effective distance between the two “plates” of the capacitor and decreasing the effective capacitance. By adjusting the doping gradient and junction width, the capacitance range can be controlled and changes can be applied using reverse voltage. A four-to-one capacitance range is not unusual; a typical varactor diode (sometimes called a “varicap diode”) might vary from Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other). Schottky diodes are used primarily in high frequency, fast-switching applications, and in many digital circuits to decrease switching times.

INSEL Rectifiers India manufactures high quality and cost-effective bridge rectifier, which provides full wave rectification from an AC power source for electronic equipment. Our line of bridge rectifiers can complete your electronic equipment’s power and case style requirements. Rectifiers An electrical circuit used to convert AC into DC current. A rectifier is a diode that causes the current to flow in only one direction. The output of the rectifier is essentially half-AC current, which is then filtered into DC. Bridge Rectifier A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This is a widely used configuration, both with individual diodes wired as shown and with single component bridges where the diode bridge is wired internally. Bridge Rectifier Advantage The main benefit of bridge rectifier over conventional full-wave rectifiers is that with a given transformer, the bridge rectifier generate a voltage output that is nearly twice that of conventional full-wave circuit. Another benefit of bridge rectifier is the low ratio of peak inverse voltage to average output voltage. A half-wave rectifier is a circuit that allows only one half-cycle of the AC voltage waveform to be applied to the load, resulting in one non-alternating polarity across it. The resulting DC delivered to the load “pulsates” significantly.
