onsemi JFETs PF5103

The PF5103 is an N-channel JFET designed for low-level analog switching in sample and hold circuits and chopper stabilized amplifiers. It is packaged in a TO-92 case with three pins labeled Drain, Source, and Gate. The device has a maximum drain-gate voltage of 40 V and a gate-source voltage of -40 V. The total device dissipation is 625 mW at 25°C, with a thermal resistance from junction to ambient of 357°C/W. The zero-gate voltage drain current ranges from 10 to 40 mA at a drain-source voltage of 15 V and a gate-source voltage of 0 V. The gate-source cutoff voltage is specified between -1.2 V and -2.7 V. The forward transfer conductance ranges from 3500 to 7500 µmhos depending on drain current. Input capacitance is 16 pF and reverse transfer capacitance is 6 pF at 1 MHz. The operating and storage junction temperature range is -55°C to 150°C.
