2N3439UA [Microchip]

This family of 2N3439 through 2N3440, high-frequency, epitaxial planar NPN transistors have a low saturation voltage, and are military qualified up to the JANS level for high-reliability applications. These transistors are available in a TO-205AD (TO-39) ,no suffix, a TO-205AA (TO-5), L suffix and a low profile surfacemount U4 and UA packaging. 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.

JEDEC registered 2N3439 through 2N3440 series.JANHC, JANKC, JAN, JANTX, JANTXV, and JANS qualifications are available per MIL-PRF-19500/368

RoHS compliant versions available (commercial grade only)

VCE(sat) = 0.5 V @ IC = 50 mA
