2N4393 Description

Short technical summary and product information.

The 2N4393 is an N-Channel JFET from Vishay Dale, part of the 2N/PN/SST4391 series designed for demanding analog switching and amplifier circuits.

 

Key electrical specifications include a drain-source breakdown voltage of 40V, drain current of 5mA at 20V, and a maximum drain-source on-resistance of 100Ω. The device features a gate-source cutoff voltage range of -0.5V to -3V and a typical turn-on time of 4ns, making it suitable for high-speed switching applications.

 

This JFET is housed in a hermetically-sealed TO-206AA (TO-18) metal can with through-hole mounting, ensuring robust mechanical and thermal performance. It operates over a junction temperature range of -55°C to 200°C and dissipates up to 1.8W.
