2N5638_D26Z

Overview

The onsemi 2N5638_D26Z is an N-channel JFET switch housed in a TO-92 package. It features a Drain-Gate Voltage of 30 V and a Gate-Source Voltage of -30 V. The device has a maximum total power dissipation of 350 mW at 25°C, with a thermal resistance from junction to case of 125 °C/W and junction to ambient of 357 °C/W. Electrical characteristics include a gate-source breakdown voltage of 30 V, a drain-source on resistance of 30 Ω, and an input capacitance of 10 pF. Switching performance specifies a turn-on delay time of 4.0 ns and a fall time of 10 ns under defined test conditions.

Feature Summary

Procurement Notes

Verify the component status as obsolete within the Fairchild Semiconductor product portfolio before procurement planning. Confirm that the D26Z suffix corresponds to the specific tape and reel or packaging configuration required by your assembly line. Ensure all electrical parameters align with legacy system requirements since this part is no longer in active production.

Selection Notes

Select this component when designing circuits requiring an N-channel JFET switch with a 30 V rating and TO-92 form factor. Evaluate the 30 Ω on-resistance and 350 mW power dissipation limits against the expected load current and thermal environment. Consider the 10 pF input capacitance for high-frequency signal integrity requirements in analog paths.

Part Context

The 2N5638 is an N-channel Junction Field Effect Transistor manufactured by Fairchild Semiconductor, now part of onsemi. It belongs to the family of discrete semiconductor switches intended for precision analog signal routing. The datasheet revision A1 indicates final specifications were established in November 2002.
