This device is constructed utilizing state-of-theart solid-state techniques and features the latest power FET output technology to minimize ON resistance. This feature provides minimum output voltage drop and allows the M33-2N to switch high pulse currents up to 100 amps at higher temperatures than those allowable with bipolar devices. The input and output are magnetically isolated to protect delicate input logic circuits from output voltage transients. The M33-2N is designed to switch loads on MILSTD-704 28 Vdc power systems, and meets 80V surge and ±600V spike requirements. The M33-2N is packaged in a low-profile hermetically sealed 22-pin DIP.
