Like all transistors, a high voltage transistor is also used for amplifying or switching electronic signals and electrical power. These are widely used in the telecom industry, networking, data storage and many more. High Voltage transistors can be packaged and used individually as well as embedded with other high voltage transistors in integrated circuits. These are the fundamental building blocks of modern electronic devices and also of prevalent electrical circuits. Various High Voltage Transistors include NPN high voltage transistor, PNP high voltage transistor and Double high voltage transistor. These are available with various technical specifications & features and at market leading rates.
Construction of High Voltage Transistors
Unlike other transistors that are usually made from silicon, high voltage transistors are constructed from the compound semiconductor material gallium arsenide and the semiconductor alloy silicon germanium. Usage of the aforesaid materials is necessary owing to the fact that high voltage transistors have to withstand higher temperatures along with consistently giving optimal performance. Also, high voltage transistors should have a much improved electron mobility which can only be achieved by using gallium arsenide and silicon germanium as their manufacturing materials.
Features of High Voltage Transistors
These are fit to be used in application areas ranging from as half bridge switch in CFL lightning, HID front lightning to use in switched mode power supply.
These are small in size and weight. Furthermore, high voltage transistors are very long lasting.
These have no cathode heaters, thus reducing the overall power consumption and also providing immunity from cathode poisoning and it's depletion.
These are resistant to breakage, leakage and wear.
High voltage transistors have a very high switching speed.
These generally also have an integrated anti parallel collector emitter diode.
