YB-4811 Semiconductor Curve Tracer Product Description (English)
The YB-4811 Semiconductor Curve Tracer is designed to visualize characteristic curves and measure static/limiting parameters of semiconductor devices such as transistors and diodes. Featuring dual-trace display capability, this compact instrument (340×250×420mm, 18kg) supports comparative analysis of paired devices. Its wide measurement ranges include collector current (10μA/div to 2A/div in 15 steps) and voltage (0.05V/div to 500V/div in 13 steps), with minimum step current of 0.1μA/level for ultra-β transistor testing. The built-in polarity switch accommodates both NPN and PNP devices, while independent channel display enhances parameter matching efficiency. Specialized circuitry enables precise reverse leakage current measurements down to 20nA/div, ideal for diode characterization. The instrument s user-friendly interface and robust design suit both R&D and production line applications.5615
