MINI-MELF-SMD Applications LL4150 or LL4150-1 Silicon Diode 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.
