Bare Die Data Sheet: 2SJ2751


Ultra-High Input Impedance N-Channel JFET Amplifier. The 2SJ2751 is ideal for use as a high-impedance sensitive front-end amplifier.
Well suited for impedance conversion applications at low frequency and low level high integration with small size sensor applications. Bare die enables smallest size with closest placement to signal source.
Features:
  • Insignificant signal loss/error voltage with high-impedance source
  • Low Power Consumption (Battery)
  • High sensitivity to low-level signals

Applications:

  • High-impedance transducer
  • Smoke detector input
  • Infra-red detector amplifier
  • Precision test equipment
  • Pyroelectric sensors

Test conditions:

  • BVGSS -40V @ IG = 100µA, VDS = 0V
  • IGSS(MAX) -1000pA @ VGS= -20V, VDS = 0V
  • VP(MAX) -3.5V @ VDS= 10V, ID= 1µA
  • IDSS(MIN) 1.4µA @ VDS= 10V, VGS = 0V
  • IDSS(MAX) 4.7µA @ VDS= 10V, VGS= 0V
  • CISS(MAX) 5pF @ VDS= 10V, VGS = 0V, f = 1MHz
  • CRSS(MAX) 1pF @ VDS= 10V, VGS = 0V, f = 1MHz
