JFETs N-Channel Transistor General Purpose
Stock Quantity: 0
The J202, manufactured by Siliconix, is a discrete N-channel Junction Field-Effect Transistor (JFET) characterized by a maximum drain-source voltage (Vds) rating of 40V. It is housed in a through-hole TO-92 package with three leads. The J202’s key electrical parameters include a typical gate-source cutoff voltage (Vgs(off)) ranging from -0.5V to -4.0V, and a zero-gate voltage drain current (Idss) typically between 2.5mA and 10mA. This device is commonly employed in low-noise amplifier and switching applications where a high input impedance and voltage-controlled current source functionality are required. The TO-92 package provides a compact form factor suitable for through-hole printed circuit board assembly.
