The DY294 Digital Transistor Analyzer Tester from YIQIXIN is a compact, handheld tool designed to quickly identify and characterize a wide range of semiconductor devices. It tests the DC parameters of diodes, transistors, silicon-controlled rectifiers (SCRs), and field-effect transistors (FETs), so you can confirm component health before you solder or repair. In addition, it measures capacitor capacitance, varistor protection voltage, and isolation of electrical parts, and it can test 78 and 79 series three-terminal voltage regulators. A bright LCD display makes readings up to 1999 easy to read at a glance, with 20 mm high digits for clear visibility in busy workspaces.

Built for portability and straightforward operation, the DY294 uses a high-sensitivity analogue-to-digital converter for accurate measurements and a simple, intuitive interface. It’s ideal for electronics factories, repair benches, labs, hobbyists, and service technicians who need quick, reliable component checks. By providing precise DC parameters and quick pass/fail indications, it reduces guesswork, speeds up troubleshooting, and minimizes wasted parts.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Since 2002, intercyprus.com has stood for reliable service and proven quality.

Benefits & Tips

  • Speed up fault finding by verifying diodes, transistors, and FETs in-circuit or as standalone components—catch bad parts before they fail in your project.
  • Use the data hold feature to capture readings in tight workspaces or when testing small components that are difficult to read directly on the display.
  • Test 78/79 three-terminal regulators and voltage references quickly to ensure your power supplies and regulators are functioning correctly, reducing downtime during assembly or repair.
