Microchip Technology, Inc. JFETs MQ2N4091UB

N-channel J-FET for analog switching and amplification applications, housed in a TO-18 package. Rated for a drain-source voltage of 40 V and gate-source voltage of -40 V, with a maximum power dissipation of 0.36 W at 25℃, derating linearly at 2.4 mW/°C above 25℃. Operating junction temperature ranges from -65℃ to +175℃, and storage temperature from -65℃ to +200℃. Matches MIL-PRF-19500/431 and is equivalent to the JAN variant. Static drain-source on-state resistance is 30 Ω at I_D = 1.0 mA, with a drain current of 30 mA at V_GS = 0 and V_DS = 20 V. Reverse transfer capacitance is 5.0 pF and input capacitance is 16 pF at 1 MHz.
