1N4947 datasheet PDF


Maximum recurrent peak reverse voltage 800 V. Maximum average forward rectified current 1.0 A.

This “fast recovery” rectifier diode series is military qualified to MIL-PRF-19500/359 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 1N5615 thru 1N5623 series where surface mount MELF package configurations are also available by adding a “US” suffix (see separate data sheet for 1N5615US thru 1N5623US). Microsemi 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 through-hole and surface mount packages.
