VOIDLESS-HERMETICALLY-SEALED
STANDARD RECOVERY GLASS
RECTIFIERS
SCOTTSDALE DIVISION
DESCRIPTION
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). 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.

AVR studio 5.0不支持mega16模拟仿真吗
尝个新鲜下载了AVR studio 5.0,没想到mega16软件模拟仿真时总是报错,而相同的软件环境仿真mega128就可以,难到这款软件支持的仿真器件不全,还是我哪里没弄好?...
