MINI-MELF-SMD Silicon Diode
1N4150UR-1
Features
Six sigma quality
Metallurgically bonded
BKC's Sigma Bond™ plating for
problem free solderability
Available in DO-35 package
Applications Switching
Used in general purpose applications, where a low current controlled
forward characteristic and fast switching speed are important.
BKC can produce generic equivalents to JAN/ TX/ TXV and S level per
MIL-S-19500/ 231 with internal source control drawings.
