Gaqqee 0–3700V IGBT Transistor & Component Voltage Tester
Gaqqee 0–3700V IGBT Transistor & Component Voltage Tester
Gaqqee 0–3700V IGBT & Component Voltage Tester
The Gaqqee IGBT Voltage Transistor Tester is a high-precision, portable instrument engineered for electronics engineers, technicians, and serious hobbyists. With a wide adjustable DC output range of 50 V to 3,700 V and a selectable output current of 50 µA to 5 mA, this tester gives you full control when characterizing semiconductors, verifying insulation integrity, and measuring breakdown thresholds across a broad range of electronic components.
Key Features
- Wide Voltage Range: Adjustable DC output from 50 V up to 3,700 V — ideal for both low- and high-voltage component evaluation.
- Dual Output Modes: Switch seamlessly between constant voltage and constant current output to suit your testing requirements.
- High Display Accuracy: 0.3% voltage display accuracy; resolution of 0.1 V below 100 V and 1 V above 100 V for precise readings every time.
- Broad Component Compatibility: Measures breakdown voltage of NMOS, PMOS, IGBTs, bipolar transistors, unidirectional thyristors, Zener diodes, LEDs, rectifier bridges, varistors, ceramic gas discharge tubes, and electrolytic capacitors.
- Insulation Voltage Testing: Verify insulation integrity between terminals of switches, push-buttons, and connectors, as well as between windings in motors, power-frequency transformers, high-frequency transformers — phase-to-phase and casing-to-core.
- Data Record Function: Onboard data-recording capability keeps your measurement history accessible for analysis and documentation.
- Built-in Safety Protections: Over-temperature cut-off at 80 °C (blue indicator light) and low-battery alert when voltage drops below 3.3 V keep you and your components safe.
- Rechargeable & Portable: 700 mAh lithium battery charged via USB Type-C (compatible with any 5 V/1 A smartphone charger); red = charging, green = fully charged.
- CE Certified: Meets CE safety standards for reliable, compliant operation.
- Compact Form Factor: 98 × 70 × 37 mm — small enough for bench work or field use.

Frequently Asked Questions
Q: What types of components can I test with this IGBT voltage tester?
A: The Gaqqee IGBT Voltage Tester supports breakdown voltage measurement for a wide range of semiconductor and passive components, including NMOS, PMOS, IGBTs, bipolar transistors, unidirectional thyristors, Zener diodes, LEDs, rectifier bridges, varistors, ceramic gas discharge tubes, and electrolytic capacitors. It also measures insulation voltage across switch terminals, connector pins, and transformer windings.
Q: Does the tester have built-in safety features for high-voltage operation?
A: Yes. The unit features an 80 °C over-temperature protection circuit that activates a blue indicator light and halts operation to protect both the tester and the component under test. A low-battery alert also triggers when the lithium cell drops below 3.3 V, preventing inaccurate readings due to insufficient power.
Q: How is the tester charged and how long does it take?
A: The tester charges via a standard USB Type-C port using any 5 V/1 A smartphone charger (not included). The built-in 700 mAh lithium battery charges at 550 mA; a red indicator light shows charging in progress, switching to green when fully charged.
Q: What is the output voltage accuracy and resolution?
A: The display accuracy is 0.3%. Voltmeter resolution is 0.1 V for readings at or below 100 V, and 1 V for readings above 100 V. The output voltage error is ±50 V, so at maximum output the actual range is approximately 3,650 V to 3,750 V.
