Schottky barrier diodes combine high rectification efficiency with
high switching speeds and low series resistance. The A8920SLR dual-
diode is designed specifically for hard-disk drive applications requiring
low voltage drop rectification of the spindle motor back-EMF during
power-down head retraction. It is supplied in a 3-lead small-outline
transistor package (SOT-23/TO-236AB) for surface-mounting for use
over the operating temperature range of -20
°
C to +85
°
C.
