Bare Die Data Sheet: 2SJ508


N-Channel high forward transfer admittance JFET with low input capacitance. The 2SJ508 is optimized for use in high frequency RF, UHF and VHF applications.
2SJ508 bare die highlights are low input capacitance: CISS = 4.8 pF (VDS = 5.0 V, ID = 10 mA, f = 1.0 MHz) & high forward transfer admittance: |yfs | = 26mS (VDS = 5.0V, VGS = 0V)
Features:
  • High forward transfer admittance
  • Low input capacitance
  • Wideband high gain
  • Very high systems sensitivity
  • High quality of amplification
  • High-speed switching capability
  • High low-level signal amplification.

Applications:

  • High-frequency amplifier / mixer
  • Mixers
  • Oscillator
  • Sample-and-hold
  • Very low capacitance switches

Test conditions:

  • BVGSS -15V @ IG = -µA
  • IGSS(MAX) -1nA @ VGS= -10V, VDS = 0V
  • VP(MIN) -0.6V @ VDS= 5V, ID= 10µA
  • VP(MAX) -3.5V @ VDS= 5V, ID= 10µA
  • IDSS(MIN) 15mA @ VDS= 5V, VGS = 0V
  • IDSS(MAX) 30mA @ VDS= 5V, VGS = 0V
  • gfs(MIN) 14mS @ VDS = 5V, ID = 10mA, f = 1 kHz
  • CISS(MAX) 4.8pF @ VDS= 5V, ID = 10mA, f = 1 MHz
  • CRSS(MAX) 1.6pF @ VDS= 5V, ID = 10mA, f = 1 MHz
