Peak Electronics Atlas DCA75 Pro Advanced Semiconductor Analyser
Use this compact tool to quickly analyse various types of component. A quick and simple method of carrying out competent analysis without extensive research.
Although it's tiny in size, the Atlas DCA Pro is an incredibly versatile instrument that can be used to connect to and analyse a large selection of components. This tester can be used in combination with transistors (including darlingtons and digital as well as silicon and germanium, MOSFETs, JFETs, IGBTs, diodes and diode networks, LEDs and bicolour LEDs, zener diodes, voltage regulators and triacs/thyristors.
Upon connection to the component the DCA Pro will automatically identify the type of component, identify the pinout and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and more. The DCA Pro can also be directly connected to a PC via the supplied USB to carry out curve tracing with various different graph possibilities.
