A high junction temperature rating and an extremely low forward ) voltage drop and thermal impedance permit high current operation with minimum space require- ments. These rectifiers may be mounted directly to a chassis or a fin or may be electrically in- sulated from the heat sink by using the mica washer insulating kit General Electric research, advanced development and product design have resulted in a highly efficient rectifying junction. This feature, plus a mechanical design employing high temperature hard solders and welds for all internal and external joints and seals, which eliminates common sources of thermal fatigue failure, has produced a silicon rectifier with outstanding reliability under all operating conditions. electrical ratings and Specifications (60 crs, resistive or inductive Load) t t 1N248 1N249 1N250 1N248A 1N249A 1N250A 1N248B 1N249B 1N250B Max.
