Schottky Diode➤ ➨It is used to suppress voltage spikes. FDMA vs TDMA vs CDMA CDMA vs GSM, ©RF Wireless World 2012, RF & Wireless Vendors and Resources, Free HTML5 Templates, Impatt Diode vs Trapatt Diode vs Baritt Diode➤. Semiconductor diode does not produce any current in the absence of applied voltage. It is basically similar to the UTP. The diode (reverse) voltage seems to have been pinned, regardless of the current henceforth, hence a voltage reference. PN diode type is used for discussion on working operation, applications etc. Impatt Diode vs Trapatt Diode vs Baritt Diode➤ The high resistive layer of the intrinsic region provides the large electric field between the P and N-region. It is economical. Following are the drawbacks or disadvantages of Diode: ➨Semiconductor diode can not withstand very high reverse voltage. At higher frequencies, PIN diode appears like an approximately perfect resistor. ➨It operates at low voltage and hence it consumes less power.
This state of diode is known as forward biased state. Some disadvantages are reverse-biased operated so no current flows. Gunn Diode | Advantages and Disadvantages Sreejith Hrishikesan September 17, 2019. It was first used in 1952 as a … The cell with low traffic speed is called as micro-cells and large high-speed traffic called macro-cells. ➨It has reverse saturation current. • There are various types of diodes. The diode has a reduced reverse recovery time. Semiconductor diode is cheaper as compared to vacuum tubes. PIN Diode➤ Advantages and Disadvantages of PIN Photodiode The advantage is its high-frequency response and its frequency response is also greater than Cadmium – Sulphide photodetector. At higher frequencies, there is not sufficient time to eliminate the charge, so the PIN diode never switched OFF. ➨It has reverse saturation current. High voltage rectifier: The PIN diode can be used as a high voltage rectifier. ➨It has long life. IMPATT diodes are economical. It provides high operating range. The power loss due to noise is low.
