Linear Systems & Bencent – High Quality Semiconductor Devices

LS logo

Linear Systems has been manufacturing high-quality discrete components since 1987, serving a wide range of markets including test equipment, professional audio, medical electronics, defense, and test & measurement. Linear Systems’ Semiconductors are known to be the best in the industry.

One of the high-quality devices designed and manufactured by Linear Systems is the LSK389, Ultra-Low Noise, Monolithic Dual N-Channel JFET amplifier.

It’s the industry’s lowest noise Dual N-Channel JFET, 100% tested, guaranteed to meet 1/f and broadband noise specification, while eliminating burst (RTN or popcorn) noise entirely. For equivalent single N-Channel version, please refer to the LSK170.


LSK389 features:

  • Ultra-Low Noise
  • High Breakdown Voltage
  • High Gain
  • Low Capacitance
  • Excellent Matching and Thermal Tracking
  • Available in SOIC 8L and thru-hole TO-71 6L packages

In addition to LSK389, Linear Systems supplies direct and improved replacements for many discrete devices currently offered or discontinued by Intersil, Interfet, National Semiconductor, Siliconix-Vishay, Fairchild, Toshiba, and Motorola.


Bencent logo
Bencent Electronics Co., Ltd was established in 1999 and has since become one of the top surge and over-voltage protection component manufacturers in China. It’s well-established product range covers components like: GDT, TVS, TSS, ESD, SPD, Zener, MOV, SCR and hybrid devices. Bencent components are widely used in industries including telecommunication, security, consumer electronics, medical devices, and automotive electronics.


Bencent’s new BMG product line combines ultra-thin gas discharge tube with a in series varistor. It’s fully compatible with existing MOV pad sizes. BMG products offer:

  • Surge ratings from 1kA to 5kA
  • Ipp ≥ 5kA @ 8/20uS
  • Maximum continuous working voltage of 70VAC to 600VAC
  • With working temperature range of -40C to +105C

Compared to simple varistor, BMG has the following advantages:

  • Improved AC voltage range
  • Improved residual voltage of the design
  • Smaller leakage current
  • Reduced PCB area due to combined design
