his section contains technical descriptions of RCA transistors, silicon rectifiers, tunnel diodes, and other semiconductor devices. It includes data on current types, as well as information on those RCA discontinued types in which there may still be some interest. Unless otherwise specified, the ratings given are based on the Absolute Maximum system. Information on solid-state photosensitive devices is shown at the end of this section. Types are listed in this section according to the numerical-alphabetical- numerical sequence of their type designations. For Key to Terminal Diagrams, see inside back cover. Oo O o GERMANIUM RECTIFIER Point-contact type used in low-power ap- plications such as isolating, clipping, and switching circuits. Maximum ratings: peak reverse volts, 60; average forward ma, 50; ambient-temperature ranze, 50 to 75C. Maximum over-all length (including leads), 414 inches; maximum diameter, 44 inch. This is a DISCONTINUED type listed for reference only. GERMANIUM RECTIFIER Foint-contact type used in large-signal power applications such as computer and clamp- ing circuits. Maximum ratings: peak reverse volts, 100; average forward ma, 50; amlbient- temperature range, 50 to 75C. Maximum over-all length (including leads), 414 inches; maxinum diameter, 14 inch. This is a DIS- CONTINUED type listed for reference only. GERMANIUM RECTIFIER Point-contact type used in large-signal power applications such as clipping, high- impedance high-voltage probe, de restorer, and high-impedance detector circuits. Maximum ratings: peak reverse voits, 50; average forward ma, 50; ambient-temperature range, 50 to 75C. Maximum over-all length (including leads), 414 inches; maximum diameter, 14 inch. This is a DISCONTINUED type listed for refereace only. GERMANIUM RECTIFIER Foint-contact type used in low-power ap- plications. Maximum ratings: peak reverse volts, 150; average forward ma, 50; ambient- temperature range, 50 to 75C. Maximum over-all length (including leads), 414 inches; maxiraum diameter, 14 inch. This is a DIS- CONTINUED type listed for reference only. IN34A IN38A IN54A IN55A
