2N3055

transistor-2n3055

The power is a 2N3055 NPN silicon transistor, low frequency, intended for general purpose applications. Its manufacture was initiated in the late 1960 by RCA, It was initially used the power transistor process hometaxial, but since the beginning of the decade 1970 It was modified for epitaxial base. commercially, the 2N3055 was used in linear power supplies, amplifiers ...

Audio transformer

transformador de audio

The speaker transformer, AF audio or transformers are transformers working at low frequencies that lie between 20Hz to 20kHz and are used primarily in audio amplifier circuits. These transformers were instrumental in the days of vacuum tubes to match the high impedance amplifier outputs with low impedance speakers. audio transformer is a transformer ...

TRIAC

TRIAC

O TRIAC faz parte da família dos tiristores, and is closely related silicon controlled rectifiers (SCR), seu nome vem do inglês Triode for Alternating Current . O TRIAC é formado por dois SCR ligados em antiparalelo, c ie, one contrary to another, but in parallel and with the gates (triggers) linked together. Com esse tipo de configuração ...

DIAC

DIAC

A DIAC, acronym of the English Diode for Alternating Current, it is a diode that conducts current only when a certain trigger voltage is reached, and driving when the electric current falls below a certain value, this value is called power failure. This occurs in both the current driving directions DIAC, this behavior is bidirectional, ...

Filtro Sallen-Key

Filtro Sallen-Key

Sallen-Key é um tipo de filtro eletrônico usado para implementar a segunda ordem de filtros ativos , que é particularmente valorizado pela sua simplicidade. O circuito produz um passa-baixa ou filtro passa-alta de dois pólos usando duas resistências, dois capacitores e um amplificador .   Para obter um filtro maior podem ser colocados varias etapas em cascata. Esses filtros são relativamente flexível ...

Tipos-de-reles

What is a DPDT relay? A DPDT relay is a relay has two separate switches that operate at the same time, each with one normally open contact or closed through a common entry. We can define the acronym as a DPDT relay two two-position switches. DPDT refers only to contacts and relay switches, não sendo relativo a sua impedância de ...

O que são Componentes Passivos

componentes passivos

Os componentes eletrônicos podem ser passivos ou ativos, os componentes passivos são os componentes eletrônicos que não aumentam a intensidade de uma corrente ou tensão de um circuito. Eles são também chamados de componentes básicos. Há quatro grandezas físicas de interesse para a eletrônica que são: voltage, flow, carga e corrente. Duas das grandezas físicas são definidos em termos das outras duas. (Atual é ...

Heatsink

dissipador de calor

As the power transistors deal with a very high current, they always heat up during operation, ie there is a heat dissipation during the process of its operation. Since the semiconductor do not support high temperatures, the heat generated to be dissipated to the environment so as to maintain the temperature within the allowable limits, so ...
