DCA55 semiconductor component analyser peak electronics
Semiconductor Component Analyser
A fresh approach to component analysis has resulted in the fantastic Peak Atlas DCA, an intelligent, slim and invaluable tool. A world of detailed component data has never been so accessible.
Just connect your component any way round and press the test button. The Atlas DCA will then present you with detailed component information in concise, easy to read, scrollable pages. The displayed information will include: the component type, special component features, component pinout, and measured parameters (such as gain, leakage current, gate threshold voltages, volt drops etc...). No more searching through data books and catalogues in order to identify components and pinouts, the Atlas does it all.
It doesn't matter how you connect the test clips to the component, the Atlas can analyse a vast number of different component types including bipolar transistors, enhancement mode MOSFETs, depletion mode MOSFETs, Junction FETs, low power thyristors and triacs (less than 5mA trigger and hold), diodes, multiple diode networks, LEDs, bi-colour and tri-colour LEDs. It will even identify special component features such as diode protection and shunt resistors in transistors. For two-leaded components such as diodes and LEDs, any pair of test clips can be applied to the component any way round, the Atlas DCA sorts it all out for you.
There is no on/off switch, power is automatically turned on at the start of an analysis and then automatically turned off if inactive for more than 30 seconds. Each page of displayed information is presented in manageable amounts, with each page being displayed when you want it. If you want to concentrate on the "pinout" page then just select that page, you don't have to see information that you don't need.
The Peak Atlas DCA is supplied complete with a long life battery, universal test probes and a comprehensive illustrated user guide.
