LL5817 LL-41 MELF SMD 1 Amp Schottky Rectifier thru ~ Use Advantages LL5819 Low forward voltage drop. Low cost replacement for SMB (same footprint). Fast switching due to majority carrier conduction which results in high operating efficiencies because of low power loss. Used in low voltage power supplies, high frequency inverters and converters, surge protection and steering diode applications BKC can produce a 1N5819UR generic equivalent to JAN/ TX /TXV levels per MIL-S-19500 / 586 with internal source control drawings. The MIL limits differ from the commercial type, consult factory for data sheet.
