## Overview

The Peak Electronic Design DCA75 Atlas DCA Pro is a professional-grade semiconductor analyzer that automatically identifies component types and pinouts, supporting a wide range of devices including transistors, MOSFETs, JFETs, IGBTs, diodes, LEDs, Zener diodes, voltage regulators, trials, and thermistors. It features low-current testing capabilities under 10 mA, precise measurements of gain, leakage, threshold voltages, and more. Compact and lightweight, powered by a single AAA battery, it is an indispensable tool for engineers and technicians seeking fast, reliable semiconductor diagnostics.

## Description

Automatic component type identification. - Automatic pinot identification (connect any way round. - The DCA pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more. Components supported include: - Transistors (including Darlington's, Silicon and Germanium types. Measures gain, Vibe and leakage. - MOSFETs, enhancement mode and depletion mode types. Measure on-threshold (at 5 mA and approx. trans conductance (for span of 3 mA-5 mA. - JFETs, including normally off Sic types. Measures pinch-off voltage (at 5 auk and approx. trans conductance (for span of 3 mA-5 mA. - IGBTs (insulated gate bipolar transistors. Measures on-threshold (at 5 mA. - Diodes and Diode networks. - LEDs and bicolour LEDs (2 lead and 3 lead types. - Zenger Diodes with measurement of sneer voltage up to 9 V at 5 mA. - Voltage regulators (measures regulation voltage, drop-out voltage, quiescent current. - Trials and Thermistors that require less than 10 mA of gate current and holding current.

Review: Invaluable test equipment. - This is a very handy piece of test equipment, to carry out tests on unknown or faulty semiconductors. This little device can save hours of homework on locating replacement components and also assist on fault finding on a faulty electronic circuitry
Review: Very useful - Very handy and useful

## Questions & Answers

**Q: Where can i get a replacement usb cable? it's not a standard micro-usb plug.**
A: Some micro USB cables are for charging of devices only and don't have the data wires.
So make sure your micro USB cable is capable of sending and receiving DATA to and from the devices its connected to.

**Q: What would you use this for, is it of value for someone who wants to repair electronics?**
A: This is great for evaluating existing components that may have been salvaged from equipment destined for the bin, or for testing suspect components which have been removed from non-functional equipment for repair.  Where this shines-through, though is in its ability to sort through a quantity of identical or similar part number devices, for the purposes of matching actual performance characteristics for a final circuit build.In testing suspect components (diodes, transistors, MOSFETs, etc.) it is best to disconnect "n-1" leads from the host circuit, to eliminate the affect of the host device from the testing, and to prevent damage to other circuit components while evaluating the device under test.  That is, if you want to save the hassle of de-soldering a lead and getting right to testing, while maintaining the DUT attachment to the circuit board--instead of losing it after removal, like I seem to do now and then.

**Q: When connected to a pc, do i have manual control over voltage/current. i need to test tunnel diodes that may get destroyed if over 1v is used?**
A: You can select a PN Junction, BJT, MOS-FET, IGBT, J-FET or a Voltage regulator to run tests to built a graph and you are able to select the Voltage and Current run between some values. Not sure it is a direct fit to your application but  you can probably tweak it to fit, if you are willing to take some risks and run some tests.

**Q: Can the screen display I-V curves?**
A: The display on the unit only gives you discrete values for the Xtor characteristics. The USB data connection allows I-V curves to be displayed on your PC. This I-V display software is supplied with the Product.
