SST174

SST174 P-CHANNEL JFET Linear Systems replaces discontinued Siliconix SST174 The SST174 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 SST174 simplifies series-shunt switching applications . ƒ ƒ ƒ ƒ ƒ Low Error Voltage High-Speed Analog Circuit Performance Negligible “Off-Error,” Excellent Accuracy Good Frequency Response Eliminates Additional Buffering FEATURES  DIRECT REPLACEMENT FOR SILICONIX SST174  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) ≤ 85Ω  ID(off) = 10pA  t(ON) 25ns  SST174 Benefits: ‐55°C to +150°C  ‐55°C to +135°C  350mW  IG = ‐50mA  VGDS = 30V  VGSS = 30V      SST174 Applications: ƒ ƒ ƒ ƒ ƒ Analog Switches Choppers Sample-and-Hold Normally “On” Switches Current Limiters   SST174 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  5  ‐‐  IDSS  Drain to Source Saturation Current  ‐20  ‐‐  IGSS  Gate Rever...
