ON Semiconductor has introduced a series of small signal PNP and NPN silicon epitaxial switching transistors in accordance with the MIL-PRF-19500 and MIL-STD-750 standards for discrete semiconductors. They are suitable for military and aerospace equipments.
The switching transistors are on the U.S. DLA (Defense Logistics Agency) Land and Maritime QPL (Qualified Products List) and are available in versions that meet JAN (Joint Army Navy), JANTX (Joint Army Navy Technical Exchange) and JANTXV quality levels. The product versions are available in hermetically sealed metal CAN packages and the extended operating and storage junction temperature ranges from -65 to +200°C.
The 2N3019S, 2N3019, and 2N3700 transistors have 80V VCEO (maximum collector-to-emitter voltage), 140V VCBO (collector-base voltage), and 1A IC (maximum DC collector current) and they are qualified per MIL-PRF-19500/391 standard. The 2N2907A and 2N2905A transistors are available in TO-18 and TO-39 packages, respectively, with -60V VCEO and VCBO, and -600mA IC. The 2N2907A transistor is qualified per MIL-PRF-19500/291 standard and the 2N2905A transistor is qualified per MIL-PRF-19500/290 standard. The 2N3019S is available in a TO-39 package. The 2N3019 is available in a TO-5 package and the 2N3700 is available in a TO-18 package.
Target applications for the MIL-PRF-19500-qualified transistors include switching and linear amplification in missile guidance, munitions, radio communications, commercial and military avionics and aerospace systems. The company claims to add transistors to its range of MIL-PRF-19500-qualified parts along with zener diodes, Schottky diodes and rectifiers.
