DCA55 Semiconductor Analyzer

I have really wanted one of these for a long time but it was hard to justify it as a need. Now that I have one I see how much of a value it is! Sure it's quick and accurate and enables you to test not guess if components need replaced but that also enables you to fix previously unfixable things. This item does feel very delicate and while it's likely plenty durable it did not come with a case so I do want to find a proper case to keep it safe yet readily available. I am impressed with how many components it can identify, it is very versatile with anything 2/3 wire. This is the kind of item that doesn't cost you money it saves it if you actually need it.

This thing is pretty handy. Its a little pricey but if you use a lot of transistors like me its will be invaluable. The DCA55 is quick to determine if its a silicon or germanium, PNP or NPN transistor and gives you pinout, HFE, VBE, leakage and test current. For diodes its more straightforward giving you forward voltage, anode and cathode. For JFETs it essentially just gives you the pin out. I have not tested MOSFETs yet. One point of advice is to not hold the transistor or diode in your hands or fingers when testing because the heat will cause the transistor or diode to read higher than actual test values.

seriously good tool, evaluates transistors and diodes nicely, also gives parameters for transistors, very helpful

As usual their products are impeccable. High quality and they perform as advertised. The build quality is exceptional and the manual, yes an actual paper manual comes with it is fantastic too!

This makes screening semiconductors so easy. It is a great device for the diy and would save pros much time in selecting and evaluating devices.

I debated purchasing one of these due to the cost but finally did and it has been worth it so far. Very easy to use and great for finding the transistor pinout and hFE for my DIY guitar pedals.

Great transistor analyzer. Gives readout for type, lead connection, gain ,voltage and leakage. Very handy instrument for making quick checks of semiconductors. Just what I needed for quick diagnostics.

This is my second DCA55. I bought my first one four years ago and recently one of the mini-grabber wires broke off. I was able to solder it back on but I don't know how long that connection will last so I ordered this one. The DCA55 is fast and convenient to determine all the specifications, gain, pin out, voltage check, leakage, etc. of transistors. Connections are able to be done quick and easy with mini-grabbers.

J'ai mesuré quelques composants dont les JFET. La réponse de l'appareil : c'est un JFET et indique la Gate, c'est totalement insuffisant comme indication ! J'avais utilisé auparavant un DCA75 qui me donnait entièrement satisfaction. Je pensais que seul le transfert vers un PC faisait la différence. La notice est mensongère.

Si te dedicas a la electrónica debes tener varios comprobadores y tésters, incluso un osciloscopio, pero si no tienes un MUY BUEN comprobador de transistores, tienes un problema. El analizador de semiconductores Peak DCA55 analiza transistores de germanio y silicio, diodos, LEDs, MOSFETs, JFETs, etc... En electrónica es importantísimo obtener la ganancia y fuga de un transistor, ya que cuando se compran, aunque tengan la misma referencia, los valores son distintos y pueden variar mucho entre unos y otros, por eso es tan importante un analizador como éste.

Strumentino che consente di valutare i parametri dei semiconduttori non tutti esiste un modello superiore , avevo un modello ormai vecchio e un poco ingombrante questo è eccezionale lo uso nelle riparazioni su amplificatori lo consiglio

Item as described, fast shipping thank you.

Nice getting a user manual, makes things much easier, this one does a little more though. The unit itself is very well made, good solid plastic and clear legible print. Make sure you discharge anything, especially capacitors, before connecting. The more I have used it the more I enjoy it.
