2N4338 Description

Short technical summary and product information.

The 2N4338 is an N-Channel JFET designed for sensitive amplifier stages at low to mid frequencies. It features a low cutoff voltage of -0.3V to -1V, making it suitable for low-voltage power supplies. The device offers a saturation drain current range of 0.2mA to 0.6mA and a common-source forward transconductance of 0.6mS to 1.8mS. Input capacitance is 7pF maximum at 15V VDS. The JFET is housed in a hermetically sealed TO-206AA (TO-18) metal can package with through-hole mounting. It operates over a junction temperature range of -55°C to 175°C and has a maximum power dissipation of 300mW. Typical applications include high-gain low-noise amplifiers, low-current battery-powered amplifiers, and infrared detector amplifiers.
