For comparison a table can be found here. The screen of the DCA55 is alphanumeric, where the screen of the DCA75 is graphical. These plots can then be exported to be used for other purposes. The Atlas DCA55 Semiconductor Tester is a handy device for testing diodes and transistors that not only identifies the type of transistor but gives you key. ![]() With the supplied software one can for example make U-I plots from components. Apart from that the DCA75 can be connected to a pc via USB. The Peak Atlas DCA is an intelligent semiconductor analyser that offers great features together with refreshing simplicity. The B&K DCA55 do not test IGBT, only the DCA75 Pro. Using the DCA75 on the PC it is possible to derive small signal gain (hfe) by grabbing some Ic graphs for various base currents and calculating slopes at various points in Excel. The 530 has worked well for some in-circuit testing that gave inconsistent results with my multimeter. The 2n404s I have test as follows: hFE 127 - leakage 0.27mA. Im fairly new to this and dont have much electronics know how beyond the basics. ![]() The DCA75 is capable of measuring more types of semiconductors than the 55. On the subject of HFE (and hfe), the main measurement parameter for gain that the DCA55 and DCA75 show is for HFE (DC current gain). Im building some fuzzes and am unsure really how to select my transistors using the Peak Atlas DCA55. A demo-video can be viewed to explain the possibilities of the DCA55 even furtherĭifferences between the DCA55 and the DCA75 The DCA55 recognizes the type of device and which pin the wires are connected to. The DCA55 comes bundled with 3 test wires that can be connected to any pin of any semiconductor. The user can browse through this data by pressing a button. The DCA55 tester can analyse a vast number of different component types including bipolar transistors, MOSFETs, thyristors, triacs, diodes, LEDs and others. 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. Once a transistor is connected to the DCA55 it automatically initiates the analysis. 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. The DCA55 by Peak Electronics is an analysis device for semiconductors. ![]()
