Additional Details:

The 2N4352 has a typical gate-source cutoff voltage (VGS(off)) of -0.5V to -4.0V. The drain current (IDSS) at VGS=0V is typically in the range of 1mA to 10mA. The transconductance (gm) is typically several millisiemens. The input capacitance is low, typically a few picofarads. The noise figure is typically less than 2dB at low frequencies. The TO-18 package is a small metal can package. When using the 2N4352, it is crucial to adhere to the maximum voltage and current ratings specified in the datasheet to prevent damage to the device. Proper biasing is essential for optimal performance.
