Peak DCA75 DCA Pro Advanced Semiconductor Component Analyser

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

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 pin-out and also measure a range of component parameters such as transistor gain, leakage, MOSFET and IGBT threshold voltages, pn characteristics and much more.

The DCA Pro supports all the components that the popular Peak Atlas DCA55 supports, but adds plenty more.

• 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 1uA) 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
• Automatic pinout identification, just connect any way round
• Special feature identification such as free-wheeling diodes and resistor shunts
• Gain measurement for bipolar transistors
• Leakage current measurement for bipolar transistors
• Silicon and Germanium detection for bipolar transistors
• Gate threshold measurement for Enhancement Mode MOSFETs
• Semiconductor forward voltage measurement for diodes, LEDs and transistor Base-Emitter junctions
• Zener voltage measurement
• PC connectivity providing: Larger component identification display
• Detailed characteristics measurement
• Curve tracing functions
• Automatic and manual power-off
