Gaqqee Optocoupler Transistor Tester – IGBT NMOS PMOS SCR

Gaqqee Optocoupler & Transistor Tester – All-in-One Electronic Component Tester

Meet the Gaqqee Optocoupler Tester — a compact, intelligent, all-in-one electronic component tester built for electronics technicians, hobbyists, and repair professionals. In seconds, this handheld device identifies and tests optocouplers, IGBTs, SCRs, NPN/PNP transistors, NMOS/PMOS tubes, and 431 voltage references — all without needing to change gears or switch modes. Simply insert the component and let the tester do the work.

Key Features

• Multi-Component Support: Tests optocouplers, IGBTs, SCRs, NPN transistors, PNP transistors, NMOS tubes, PMOS tubes, 431 regulators, and more — all from a single device.
• Instant Smart Identification: Intelligent auto-detection identifies component type and status in seconds — no manual range shifting required.
• Status Indicator Light: Built-in component judgment indicator light — green means the component is functioning correctly, giving you a fast visual confirmation.
• Digital Display: Clear digital readout for quick, accurate test result reading at a glance.
• Durable Copper Test Port: Copper-constructed component test port withstands repeated insertions and removals, extending the device's operational lifespan and ensuring reliable electrical contact.
• USB Type-C Charging (Rechargeable Model): The TO2P model features a built-in polymer lithium-ion battery charged via Type-C — no external power supply needed. The TO2 plug-in model powers directly via Type-C as well.
• Ergonomic One-Handed Design: Slim 15.9 × 2.2 × 1.3 cm form factor fits comfortably in one hand for extended use without fatigue.
• CE & RoHS Certified: Meets CE and RoHS compliance standards for quality and safety assurance.
• Ultra-Low Power Consumption: Designed for long battery life and lasting durability in daily repair workflows.

Frequently Asked Questions

Q: What types of electronic components can the Gaqqee Optocoupler Tester test?

A: This all-in-one tester supports optocouplers, IGBTs, SCRs, NPN transistors, PNP transistors, NMOS tubes, PMOS tubes, and 431 voltage reference ICs. No gear shifting is needed — the device automatically identifies the component type and delivers results in seconds.

Q: What is the difference between the TO2 and TO2P models?

A: The TO2 model is a plug-in version that draws power directly from a Type-C connection and does not include a built-in battery. The TO2P model features a built-in rechargeable polymer lithium-ion battery, making it fully portable — you can use it anywhere without being tethered to a power source.

Q: Does the tester require any manual configuration to identify a component?

A: No manual range or mode switching is required. The Gaqqee tester uses intelligent auto-detection to identify the component type and report its condition automatically. Simply insert the component into the copper test port and read the result on the digital display — the green indicator light confirms normal component status.

Q: Is a battery included with the tester?

A: The TO2 (plug-in) model does not include or require a battery — it is powered via Type-C. The TO2P (rechargeable) model includes a built-in polymer lithium-ion battery that is charged via the Type-C port.
