Description
General part information
1N4249US-Rectifier-Diode Series
This "standard recovery" rectifier diode series is military qualified to MIL-PRF-19500/286 and is ideal for high-reliability applications where a failure cannot be tolerated. These industry-recognized 1.0 Amp rated rectifiers for working peak reverse voltages from 200 to 1000 volts are hermetically sealed with voidless-glass construction using an internal "Category I" metallurgical bond. These devices are similar in ratings to the 1N5614 thru 1N5622 series where surface mount MELF package configurations are available by adding a "US" suffix (see separate data sheet for 1N5614US thru 1N5622US). Microchip also offers numerous other rectifier products to meet higher and lower current ratings with various recovery time speed requirements including fast and ultrafast device types in both throughhole and surface mount packages.
