TRANSISTOR WATER ENTRY SHOCK RESISTANCE SURVEY FOR RUGGEDIZED SONOBUOY

Abstract

Transistor types 2N169A, 2N220, 2N200, and 2N741 were tested for their resistance to water-entry shock. A total of 147 transistors was mounted in one of three ways: (1) polyethylene holder and potted in polyethylene, (2) polyethylene holder and potted in Dow-Corning 601, and (3) potted in Dow-Corning 601 alone. The polyethylene holder and the 601 potting proved to be the most shock resistant mounting method. All of the transistors proved to be sufficiently rugged to survive the water-entry shock expected in service use of the NOL free fall miniature Sonobuoy.
