Key Features

  • guaranteed peak operating voltage minimum of 100 V with a typical of 180 V. The J500 series features 50 V minimum with a typical of 100 V. The lower current devices in both series provide excellent current regulation down to as little as 1 V. Siliconix 10-Mar-97 Bias Resistor Selection All industry JFET part types exhibit a significant variation in IDSS and VGS(off) on min/max specifications and device-to-device variations. Using the simple source biasing current source as illustrated in Figure.
