SCR 5162

Abstract: EQUIVALENT 2N1671 UNIJUNCTIONS CONVENTIONAL General Electric produces a very broad line of standard UJT's. The TO-5 ceramic disc bar structure device has been the workhorse of the unijunction industry for over 10 years. MIL versions are available on the 2N489-494 series. Equivalent types are available in TO-18 packages where small size is required. The cube structure TO-18 series offers excellent value for those requiring proved, low cost units.
