Atlas DCA Pro - Advanced Semiconductor Analyser with Curve Tracing

by Peak

Identify electronic components such as transistors and diodes and analyse their performance. How good is that reel of stuff you got from the internet?

Building on the continued success of Peak's existing component identification and analysis instruments, the DCA Pro brings an array of exciting new features for the hobbyist and professional alike.

Key Features

The DCA Pro is an advanced new design that features a graphics display, USB communications, PC Software and an enhanced component identification library.

  • Automatically identify part type (eg, Transistor, JFET, IGBT, Regulator, Zener, Diodes, etc)
  • Automatically identify pinout (connect any way round)
  • Measure lots of component data
  • Perform further detailed component analysis with the PC software included on the Peak USB flash drive (suitable for Windows® XP to Windows® 10)
  • Complete with premium gold plated hook probes
  • Online upgradeable
  • Single alkaline AAA battery included (not used when connected by USB)
  • 24 month warranty as standard.

Components supported include:

  • Transistors (including Darlingtons), Silicon and Germanium types. Measures gain, Vbe and leakage.
  • MOSFETs, enhancement mode and depletion mode types. Measure on-threshold (at 5mA) and approx transconductance (for span of 3mA-5mA)
  • JFETs, including normally off SiC types. Measures pinch-off voltage (at 5uA) and approx transconductance (for span of 3mA-5mA)
  • IGBTs (insulated gate bipolar transistors). Measures on-threshold (at 5mA). - Diodes and Diode networks.
  • LEDs and bicolour LEDs (2 lead and 3 lead types).
  • Zener Diodes with measurement of zener voltage up to 9V at 5mA
  • Voltage regulators (measures regulation voltage, drop-out voltage, quiescent current)
  • Triacs and Thyristors that require less than 10mA of gate current and holding current.

Stand-alone or with a PC (Windows® XP to Windows® 10)

The instrument can be used stand-alone or connected to a PC. Either way, the DCA Pro will automatically identify the component type, identify the pinout and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and much more.

Curve Tracing

When connected to a PC using the supplied USB cable, a range of low current curve-tracing functions can be performed. Various graph types are available, with more to follow:

  • Bipolar transistor output characteristics, IC vs VCE
  • Bipolar transistor gain characteristics, hFE vs VCE
  • Bipolar transistor gain characteristics, hFE vs IC
  • MOSFET and IGBT output function, ID vs VDS
  • MOSFET and IGBT transfer function, ID vs VGS
  • JFET output function, ID vs VDS
  • JFET transfer function, ID vs VGS
  • Voltage regulator, VOUT vs VIN
  • Voltage regulator, IQ vs VIN
  • PN junction I/V curves, forward and reverse options (for Zener diodes).

Curve tracing is performed using test parameters in the range of +/-12V, +/-12mA. All curve-tracing data can be instantly pasted into Excel© for further graphing and analysis. PC Software is included with the DCA Pro on a Peak USB memory stick. Software designed for Windows XP, Vista, 7, 8 and 10.
