2N4858A Description

Short technical summary and product information.

The 2N4858A is an N-Channel silicon JFET from Central Semiconductor Corp, designed for analog switching and chopper applications. It features a maximum drain-source voltage of 40V and a forward gate current of 50mA. The device offers a drain current (IDSS) range of 8mA to 80mA at VDS=15V and VGS=0, with a typical drain-source on-resistance of 60Ω.

 

This JFET provides fast switching performance with typical delay and rise times of 8ns and a turn-off time of 80ns under specified test conditions. Input capacitance is 10pF maximum and reverse transfer capacitance is 3.5pF maximum, making it suitable for low-noise switching circuits.

 

The 2N4858A is housed in a TO-18 (TO-206AA) metal can package with through-hole mounting and a 3-lead configuration. It operates over a junction temperature range of -65°C to 200°C and has a maximum power dissipation of 360mW. The device is RoHS3 compliant and has an MSL rating of 1 (unlimited).
