2N5115JAN02 is listed in the Jfets range at ChipApex. The manufacturer field lists Vishay Siliconix. Its product description is JFET P-CH TO206AA. Review the specifications below when checking this part for your BOM.
The Vishay Siliconix 2N5115JAN02 is a P-channel silicon small-signal Junction Field-Effect Transistor (JFET) designed for high-reliability applications. It features a TO-206AA (TO-18) metal can package with three terminals. Key electrical specifications include a minimum drain-source breakdown voltage of 30 V and a maximum drain-source on-resistance of 100 Ω. The device operates in depletion mode and exhibits a maximum feedback capacitance (Crss) of 7 pF. This component is classified as a single-element discrete semiconductor suitable for rugged environments.
Verify the specific manufacturer source, as historical data indicates production by both Vishay Siliconix and Microsemi. Confirm RoHS compliance status, as some variants are marked non-compliant. Ensure the ordering suffix matches the required radiation hardness or quality level. Check current availability status, as this part number may be listed as obsolete or limited supply in certain distributor catalogs. Validate datasheet revisions to ensure parameter consistency.
Select this component when a P-channel JFET with a hermetic metal package is required for harsh environments. The 30 V breakdown voltage limits its use to low-voltage signal processing stages. Consider the 100 Ω on-resistance for impedance matching requirements. The TO-18 package dictates specific PCB mounting or panel mount constraints compared to surface-mount alternatives.
This device belongs to the standard military-grade JFET family, often referenced under similar designations like JANTX2N5115. It serves as a discrete semiconductor solution for specialized analog front-ends where standard commercial components lack sufficient durability. The TO-206AA form factor is a legacy industry standard for through-hole integration in shielded enclosures.
Public confirmed substitute part numbers include JANTX2N5115.
