The Western Electric 2N1072 is a diffused junction silicon NPN mesa power transistor, specially developed for use as a core memory driver in the Nike Zeus anti-ICBM missile system. The 2N1072 is a rugged device capable of high current, high frequency operation in high temperature environments, and was the first device to use the TO-38 package, a cold welded, vacuum-sealed canister.
