File No. 505 CEU Solid State Division RF Power Transistors 2N5919A Features: JEDEC TO-216AA H.1693 RCA Type 2N5919A is an epitaxial silicon n-p-n planar transistor with overlay emitter-electrode construction. The 2N5919A is unilaterally interchangeable with the 2N5919. Both types employ a construction which features many separate emitter elements; however, for stabilization, the 2N5919A has integral emitter ballast resistance. @ Formerly RCA Dev. No.TA7532.
