JSCJ ESD and Surge Protection Devices

Voltage Suppressor / ESD Protection / Zener Diode


The abbreviation JSCJ stands for Jiangsu Changjing Electronics Co. Ltd., a strongly emerging young company located in the city of Nanjing in Jiangsu province, China. JSCJ is the offspring of JCET, one of TOP3 of World’s biggest OSAT (Outsourced Semiconductor Assembly & Test) companies and dedicated (with this powerful background) to become one of the leading players in its market for semiconductor products.

JSCJ is offering a huge variety of products to address markets in the Industry, Consumer and Whitegoods sector and is furthermore continuously advancing into Automotive applications is focusing diodes, transistors, frequency devices (Crystal and Oscillator) and ICs with an ever-growing product portfolio. JCET, not only serves its own brand “JSCJ” but also many international semiconductors companies as ODM partner, has industry leading quality standards and carries certificates like ISO9001, ISO14001, OHSAS18001 and IATF16949.

JSCJ and BECK ELEKTRONIK cooperate from the very early stage of the founding of the brand “JSCJ” in 2019.


Transient Voltage Suppressors

TVS Diodes are electronic components that can protect sensitive electronics from high-voltage transients. They can protect the circuits efficiently due to shorter respond time to overvoltage events in comparision with most other types of circuit protection devices. They can limit the voltage to a curtain level by conducting large currents to ground which are usually generated by lightning strikes, load switch and electro-static discharge (ESD) etc.

JSCJ's TVS diode (max. 9180W Pppm) and High Power TVS diode (max. 15000W Pppm) belong to product family Diode.

Zener Diode & Array

Zener Diode is a type of diode that can limit voltage to the conventional maximal value and allow current to flow in opposite direction (backwards) due to Zener effect.

JSCJ provides over 1000 diffirent zener diodes with zener voltage from 1,71 V to 95,5 V and max. power dissipation up to 5000 mW. JSCJ's zener diode belong to product family Diode.
