DESCRIPTION
SMA
(JEDEC DO-214AC)
The UTC SR22 THRU SR26 is a 2.0A Schottky Barrier Rectifiers,
it uses UTC’s advanced technology to provide customers with low
forward voltage drop, low reverse current and high efficiency, etc.
The UTC MBR1100 is suitable for free wheeling diodes, high
frequency inverters, low voltage and polarity protection diodes.
