ETCR3850 Transient Voltage Suppressors (TVS) Tester is specially designed for TVS diode performance index test, it is an industrial-grade tester. It is composed of host, LCD liquid crystal display screen, software, power adapter and so on. Compared with traditional Zener diodes, TVS diodes have the advantages of faster response speed and other advantages, and are widely used in circuit design. Therefore, in order to ensure the performance of products, it is particularly important to test the performance of each diode that leaves the factory. Among the performance indicators of TVS diodes, the most important indicator is "reverse breakdown voltage". This tester is designed for the detection of this indicator.

Compared with the traditional measuring tester, this tester adds the LCD liquid crystal display function, which is convenient for the user to operate and display the test results. The LCD display parts are mainly divided into voltage threshold input, qualified judgment, test result display, real-time voltage & current display, measurement record usage, battery power display, test record display and test record operation etc. The hardware design of the power button and other function buttons are also different. This tester adopts rotary switch, which has a longer service life than the traditional buttons and is more convenient to use. In terms of power supply, this tester is powered by a rechargeable lithium battery. It is easy to carry, and you only need to fully charge it when working in places without electricity. Compared with traditional dry batteries, it is more durable and more environmentally friendly.
