JSCJ Transistors

Bipolar / Darlington / MOSFET


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.


Bipolar Junction Transistors / BJT

A Bipolar Junction Transistor (BJT) has either a npn-structure or a pnp-structure and therefore comprises two subsequent pn-junctions. The currents are combined negatively charged electrons and positively charged holes as charge carriers. Bipolar junction transistors are usually used in two different types of applications: switching and amplification.

JSCJ has a broad portfolio of transistors for several different purposes and applications. Highlights are a low VSAT and the full range of digital transistors.

Darlington Transistor

A Darlington Transistor consists of two single transistors, that are working closely toegether to amplify the current. Use cases are the amplification of analog signals and other applications, where a high current gain is necessary.

JSCJ has a wide range of Darlington Transistors with VCEO ranging from 30V up to 100V and a collector current IC ranging from 0,3A up to 10A.

Small Signal Mosfet & Power Mosfet

A MOSFET (Metal-oxide-semiconductor field-effect transistor) is a type of insulated-gate field-effect transistor which is widely used for switching and amplifying signals with the capability to work up to a few hundred KHz.

JSCJ's MOSFET portfolio offers a range of breakdown voltages from –100V to 800V combined with state-of-the art packaging. They aim for the consumer market for applications like wireless charger, motor drivers, security equipment, Li-Ion battery protection etc.

JSCJ’s has released a CSP (chip scale packaging) Power Mosfet CJ6207SP:

The CJ6207SP uses advanced trench technology to provide excellent RSS(ON) (common Drain topology) , low gate charge and operation with gate voltages as low as 2.5 V while retaining an 8 V VGS(MAX) rating. It is ESD protected. This device is suitable for use as a unidirectional or bi-directional load switch, facilitated by its common-drain configuration. The very tiny package CSP targets for space limited applications like wearables and cell phones.
