LSJ177

LSJ177 P-CHANNEL JFET Linear Systems replaces discontinued Siliconix J177 The LSJ177 is a single P-Channel JFET switch This p-channel analog switch is designed to provide low on-resistance and fast switching. When used in combination with the complimentary J/SST111 nchannel family, the LSJ177 simplifies series-shunt switching applications . Low Error Voltage High-Speed Analog Circuit Performance Negligible “Off-Error,” Excellent Accuracy Good Frequency Response Eliminates Additional Buffering FEATURES  DIRECT REPLACEMENT FOR SILICONIX J177  LOW ON RESISTANCE  LOW GATE OPERATING CURRENT  FAST SWITCHING  ABSOLUTE MAXIMUM RATINGS   @ 25°C (unless otherwise noted)  Maximum Temperatures  Storage Temperature  Operating Junction Temperature  Maximum Power Dissipation  Continuous Power Dissipation   MAXIMUM CURRENT Gate Current (Note 1)  MAXIMUM VOLTAGES  Gate to Drain Voltage  Gate to Source Voltage      rDS(on) ≤ 300Ω  ID(off) = 10pA  t(ON) 25ns  LSJ177 Benefits: ‐55°C to +150°C  ‐55°C to +135°C  350mW  IG = ‐50mA  VGDS = 30V  VGSS = 30V      LSJ177 Applications: Analog Switches Choppers Sample-and-Hold Normally “On” Switches Current Limiters   LSJ177 ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL  CHARACTERISTIC  MIN  TYP.  BVGSS  Gate to Source Breakdown Voltage  30  ‐‐  VGS(F)  Gate to Source Forward Voltage  ‐‐  ‐0.7  VGS(off)  Gate to Source Cutoff Voltage  0.8  ‐‐  IDSS  Drain to Source Saturation Current  ‐1.5  ‐‐  IGSS  Gate Reverse Current  ‐‐  0.01  IG  Gate Operating Current  ‐‐  0.01  ID(off)  Drain Cutoff Current  ‐‐  ‐0.01  rDS(on)  Drain to Source On Resistance  ‐‐  ‐‐          LSJ177 SWITCHING CHARACTERISTICS @ 25°C (unless otherwise noted)  SYMBOL  CHARACTERISTIC    UNITS  td(on)  tr  td(off)  tf  Turn On Time  Turn On Rise Time  Turn Off Time  Turn Off Fall Time  10  15  10  20      ns  Click To Buy   nA    Ω    CONDITIONS  VGS(L) = 0V   VGS(H) = 10V    See Switching Circuit                      Available Packages: LSJ177 in SOT-23 LSJ177 in bare die.
