JSCJ ESD and Surge Protection Devices

Voltage Suppressor / ESD Protection / Zener Diode


Jiangsu Changjing Electronics Co. Ltd. (abbreviation: JSCJ), is a dynamic company based in Nanjing, Jiangsu Province, of China. JSCJ is a spin-off of the Discrete Device Division of its parent company Jiangsu Changjiang Electronics Technology Co., Ltd. (JCET), one of the TOP3 largest OSAT (Out-sourced Semiconductor Assembly & Test) companies in the world. JSCJ aims to become one of the leading players in the semiconductor market.

JSCJ offers a broad portfolio of semiconductor components for the industrial, consumer and white goods markets and is focusing on expanding its product range of AEC-Q101 certified products. In addition to traditional active components, JSCJ also has frequency-devices such as crystals and oscillators in its line card. JSCJ meets industry quality standards and is certified to ISO 9001, ISO 14001, OHSAS 18001 and IATF 16949.

The partnership between BECK and JSCJ started at the early beginnings of 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.
