STTH6004W Datasheet

STTH6004W Manufacturer

STMicroelectronics is a French-Italian multinational electronics and semiconductors manufacturer headquartered in Plan-les-Ouates near Geneva, Switzerland. The company resulted from the merger of two government-owned semiconductor companies in 1987: "Thomson Semiconducteurs" of France and "SGS Microelettronica" of Italy. It is commonly called "ST", and it is Europe's largest semiconductor chip maker based on revenue. While STMicroelectronics corporate headquarters and the headquarters for EMEA region are based in the Canton of Geneva, the holding company  , STMicroelectronics N.V. is incorporated in the Netherlands.

Note: Please check their parameters and pin configuration before replacing them in your circuit.



What is a Ultrafast rectifier?

A fast diode is a faster-than-standard current rectifier. A “fast” rectifier typically recovers ten times faster than a standard rectifier, and an “ultrafast” designation is usually applied to rectifiers designed to beat the standard rectifier recovery by being more than fifty times faster.


What is high voltage rectifier?

Generation of high d.c. voltages

Normally, for the generation of d.c. voltages of up to 100 kV, electronic valve rectifiers are used and the output currents are about 100 mA. The a.c. supply to the rectifier tubes may be of power frequency or may be of audio frequency from an oscillator.


What is diode rectifier?

A rectifier is a special type of diode that converts alternating current (AC) into direct current (DC). This is an important process, as alternating current is able to reverse direction periodically, while direct current consistently flows in a single direction, making it simple to control.


Which type of rectifier is mostly used?

Bridge rectifier is the most commonly used rectifier in electronics and this report will deal with the working and making of one. Simple bridge rectifier circuit is the most popular method for full wave rectification.


What is the difference between a voltage regulator and a rectifier?

A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). A Regulator is an electrical or electronic device that maintains the voltage of a power source within acceptable limits.
