Advanced Semiconductor Tester with Curve Tracing

Analyze semiconductors easily with the Peak DCA75: Atlas DCA Pro Semiconductor Tester with Curve Tracing. The new Atlas DCA75 Pro transistor tester offers superb functionality and style. The analysis portfolio is even bigger than the DCA55 while offering enhanced message display and intelligent component identification. This instrument displays incredibly detailed information in fully scrollable pages. The Peak Atlas DCA Pro combines an impressive analysis portfolio that is user-friendly. It will measure the gain of transistors, the threshold voltage of MOSFETs, and semiconductor voltage drops. The Atlas DCA75 has more component testing capabilities than the DCA55, but also offers full curve tracking which is downloadable to an Excel file (via USB).


Features

  • Stand-alone or with a PC
  • Automatic component type identification
  • Automatic pinout identification
  • Special feature identification such as protection diodes and resistor shunts
  • Bipolar transistors: gain and leakage current measurements, silicon and germanium detection
  • Gate threshold measurement foreEnhancement Mode MOSFETs
  • Semiconductor forward voltage measurement for diodes, LEDs and transistor base-emitter junctions
  • Automatic and manual power-off

    Amazing piece of gear for a fantastic price.

    After checking everywhere, Velleman store is the cheapest place in the USA to buy this unit. With the free ground shipping it was $150 to my door. The UPS ground took around 3 days to arrive.

    As far as the unit, you can find plenty of reviews on eevblog and other various sites. They are all universally positive. The company which produces the unit responds to user concerns personally, and all manufacturing is done in the UK. Firmware is updates constantly as new features are added, some due to end user input.

    It takes a AAA battery (included), and also includes a USB stick with the Windows software which allows you to use it with basic functionality as well as basic curve tracing features, which are:

    BJT
    * Ic / Vce
    * HFE / Vce
    * HFE / Ic

    MOSFET
    * Id / Vds
    * Id / Vgs

    IGBT
    * Ic / Vce
    * Ic / Vge

    JFET
    * Id / Vds
    * Id / Vgs

    Voltage reg (up to 12V)
    * Vout & Iq / Vin

    The unit works off of USB power when plugged in to a computer (no batt needed).

    I created a basic breakout board to easily pop in an out transistors for test and comparison. To-92, To-18, To- 220, To-3, etc. You can see a picture of it here:
