Description

General part information

JANTX2N3421S-Transistor Series

This family of 2N3418 through 2N3421 high-frequency, epitaxial planar NPN transistors have a low saturation voltage, and are military qualified up to the JANS level for high-relliability applications. These transistors are available in a standard TO-205AA (TO-5) package as well as a TO-205AD (TO-39) package, when S suffix and a low profile surfacemount U4 packages. Microchip also offers numerous other transistor products to meet higher and lower power ratings with various switching speed requirements in both through-hole and surface-mount packages.
