DUAL SCHOTTKY DIODE

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.
