U290

Overview

The Vishay Siliconix U290 is an N-channel JFET analog switch housed in a hermetically sealed TO-206AC (TO-52) package. It features a gate-source cutoff voltage range of -4.0 V to -10 V, a maximum drain-source on-resistance of 3 Ω at 1 mA, and a typical turn-on time of 14 ns. The device supports a saturation drain current of up to 500 mA and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

Low on-resistance for minimal signal loss
Fast switching capability with 14 ns turn-on time
High off-isolation and low capacitance
Hermetically sealed military-grade packaging

Applications

Analog switches
Choppers
Sample-and-hold circuits
Normally 'on' switches
Current limiters

Procurement Notes

Verify the specific ordering suffix, such as -E3, against the official datasheet to ensure compliance with material specifications. Confirm that the TO-206AC package matches the required footprint and thermal constraints for the target application environment.

Selection Notes

Select the U290 when low on-resistance and high-speed switching are critical requirements. Ensure the system voltage does not exceed the absolute maximum ratings. Consider the TO-206AC package size and hermetic sealing benefits for rugged or aerospace environments compared to standard plastic packages.

Part Context

The U290 belongs to a series of high-performance JFET analog switches designed by Vishay Siliconix. It is distinguished by its industry-low on-resistance and fast switching speeds. The companion U291 variant offers different cutoff characteristics but shares similar dynamic performance metrics.
