2N3819 Description

Short technical summary and product information.

The 2N3819 is a silicon N-Channel JFET from Central Semiconductor, designed for RF amplifier and mixer applications. It is housed in a TO-92 through-hole package with a lead code of 1 Drain, 2 Gate, 3 Source.

 

Key electrical characteristics include a maximum drain-source voltage (VDS) of 25V, a drain current (IDSS) range of 2.0 to 20 mA at VDS=15V, and a forward transconductance (|Yfs|) of 2.0 to 6.5 mS at 1 MHz. The device also features low input capacitance (Ciss) of 8.0 pF typical and reverse transfer capacitance (Crss) of 4.0 pF typical, making it suitable for high-frequency circuits.

 

The 2N3819 operates over a junction temperature range of -65°C to +150°C and has a maximum power dissipation of 360 mW. It is commonly used in RF amplifier stages, mixers, and other analog switching applications.
