J310 N-CHANNEL JFET Linear Systems replaces discontinued Siliconix J310 The J310 is a high frequency n-channel JFET offering a wide range and low noise performance. The TO-92 package is well suited for cost sensitive applications and mass production. (See Packaging Information). High Power Low Noise gain Dynamic Range greater than 100dB Easily matched to 75Ω input J310 Applications: Gpg = 11.5dB NF = 2.7dB Maximum Temperatures Storage Temperature Operating Junction Temperature Maximum Power Dissipation Continuous Power Dissipation MAXIMUM CURRENT Gate Current MAXIMUM VOLTAGES Gate to Drain Voltage or Gate to Source Voltage J310 Benefits: FEATURES DIRECT REPLACEMENT FOR SILICONIX J310 OUTSTANDING HIGH FREQUENCY GAIN LOW HIGH FREQUENCY NOISE ABSOLUTE MAXIMUM RATINGS @ 25°C1 UHV / VHF Amplifiers Mixers Oscillators J310 ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTIC MIN BVGSS Gate to Source Breakdown Voltage ‐25 VGS(F) Gate to Source Forward Voltage 0.7 VGS(off) Gate to Source Cutoff Voltage ‐2 IDSS Drain to Source Saturation Current2 24 IG Gate Operating Current (Note 3) ‐‐ rDS(on) Drain to Source On Resistance ‐‐ UNIT V ‐55°C to +150°C ‐55°C to +135°C 350mW 10mA ‐25V TYP. ‐‐ ‐‐ ‐‐ ‐‐ ‐15 35 MAX ‐‐ 1 ‐6.5 60 ‐‐ ‐‐ J310 DYNAMIC ELECTRICAL CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTIC MIN TYP. gfs Forward Transconductance 8 14 gos Output Conductance ‐‐ 110 Ciss Input Capacitance ‐‐ 4 Crss Reverse Transfer Capacitance ‐‐ 1.9 en Equivalent Noise Voltage 6 ‐‐ MAX ‐‐ 250 5 2.5 ‐‐ UNIT mS µS pF VDS = 10V, VGS = ‐10V , f = 1MHz nV/√Hz VDS = 10V, ID = 10mA , f = 100Hz J310 HIGH FREQUENCY CHARACTERISTICS @ 25°C (unless otherwise noted) SYMBOL CHARACTERISTIC MIN TYP MAX UNIT CONDITIONS dB dB mA pA Ω CONDITIONS VDS = 0V, IG = ‐1µA VDS = 0V, IG = 10mA VDS = 10V, ID = 1nA VDS = 10V, VGS = 0V VDG = 9V, ID = 10mA VGS = 0V, ID = 1mA Click To Buy NF Noise Figure Gpg Power Gain3 gfg Forward Transconductance gog Output Conductance f = 105MHz f = 450MHz f = 105MHz f = 450MHz f = 105MHz ‐‐ ‐‐ ‐‐ ‐‐ ‐‐ 1.5 2.7 16 11.5 14 ‐‐ ‐‐ ‐‐ ‐‐ ‐‐ f = 450MHz ‐‐ 13 ‐‐ f = 105MHz ‐‐ 0.16 ‐‐ f = 450MHz ‐‐ 0.55 ‐‐ CONDITIONS VDS = 10V, ID = 10mA , f = 1kHz VDS = 10V, ID = 10mA mS Note 1 ‐ Absolute maximum ratings are limiting values above which J310 serviceability may be impaired.
