Gaqqee LCR-D2 Transistor Tester | LCR MOSFET IR Decoder
Gaqqee LCR-D2 Transistor Tester – All-in-One Component Analyser
The Gaqqee LCR-D2 Transistor Tester is a compact, professional-grade measuring instrument designed for electronics enthusiasts, technicians, educators, and product developers. Packed into a pocket-sized 90 × 70 × 19 mm body, it delivers automatic and manual component identification with a clear 1.44-inch digital display — making it the ideal bench companion for testing transistors, MOSFETs, diodes, capacitors, inductors, resistors, and more.
Key Features
- Auto & Manual Modes: In Auto Mode the device automatically recognises the component type at the press of a button. Manual Mode lets you dial directly to the component category you need — the matching icon appears on screen instantly.
- Interchangeable SMD Socket: The swappable surface-mount socket accommodates a wide variety of SMD components, making bench testing faster and more flexible.
- MOSFET & Transistor Testing: Accurately identifies and measures BJTs, MOSFETs, JFETs, and more, displaying key parameters on the digital screen.
- LCR Measurement: Measures capacitance, inductance, and resistance across a broad auto-range, removing the guesswork from component sorting.
- NEC Infrared Signal Decoding (NRC): Built-in IR decoding supports NEC protocol remote control testing and displays corresponding infrared waveforms — great for remote control diagnostics.
- Self-Test / Calibration: Short-circuit pins 1-2-3 in the transistor test area, hold the TEST button for 3 seconds, and the unit runs a full self-calibration routine.
- Data Record Function: Saves test results for review, supporting efficient multi-component workflows.
- USB Type-C Charging: Rechargeable 400 mAh built-in lithium battery (5 V / 1 A via Type-C) — no disposable batteries needed.
- CE & RoHS Certified: Meets international safety and environmental standards.

Frequently Asked Questions
Q: What types of components can the Gaqqee LCR-D2 Transistor Tester identify?
A: The LCR-D2 can automatically or manually identify and measure a wide range of electronic components including BJT transistors, MOSFETs, JFETs, standard diodes, Zener diodes, capacitors, inductors, and resistors. Its auto-range mode recognises the component type without manual configuration.
Q: Does the LCR-D2 need batteries, and how is it charged?
A: The LCR-D2 has a built-in 400 mAh rechargeable lithium-ion battery — no replaceable batteries are required. It charges via the included USB Type-C cable at 5 V / 1 A, making it convenient to top up from any standard USB charger or power bank.
Q: What infrared protocol does the NRC IR decoding feature support?
A: The built-in infrared signal decoder supports the NEC protocol. It decodes NEC-format remote control signals and displays the corresponding infrared waveforms on the 1.44-inch screen, making it ideal for remote control diagnostics and testing.
Q: How do I calibrate or self-test the LCR-D2?
A: To run a self-test / calibration, short-circuit pins 1, 2, and 3 in the transistor test area simultaneously, then press and hold the TEST button for 3 seconds. Ensure the Zener diode test area remains open during this procedure. The device will then run its built-in calibration routine automatically.
