The DCA75 by Peak Electronics is an analysis device for semiconductors. The measurement device can, amongst others analyse bipolar and Darlington transistors, various MOSFETs, FETs, triac's thyrisistors and multiple diodes like for example single color LEDs.
Once a transistor is connected to the DCA75 it automatically initiates the analysis. It determines the type of semiconductor that is connected and measures the data specific to the type, for example characteristic voltages or Pinout of the device. The user can browse through this data by pressing a button.

The DCA75 comes bundled with 3 test wires that can be connected to any pin of any semiconductor. The DCA75 recognizes the type of semiconductor and which pin each of the wires are connected to. A demo-video can be viewed to explain the possibilities of the DCA75 even further.

Differences between the DCA55 and the DCA75

The DCA75 is capable of measuring more types of semiconductors than the DCA55. Apart from that the DCA75 can be connected to a pc via USB. With the supplied software one can for example make U-I plots from components. These plots can then be exported to be used for other purposes. The screen of the DCA55 is alphanumeric, where the screen of the DCA75 is graphical. For comparison a table can be found here.
