Key Features
! Very low forward voltage drop (VF):
-- VF(MAX) @ IF = 0.5A: 400mV
-- VF(MAX) @ IF = 0.1A: 300mV
! High average rectified current rating for a SOD-323 device (IO): 400mA.
Benefits
1. Low power loss / highly efficient.
2. Can operate at very high frequencies / conducive to switch-mode circuits.
3. Very small package allows for greater circuit density and reduced PCB area consumption.

Crosses to Other Manufacturers’ Parts
! Near equivalent to:
o Rohm RB551V-30
o Central Semi CMDSH2-3
o Infineon BAT60B
Ways B0520WS Surpasses Its Competition
! Rohm RB551V-30
o Our B0520WS offers lower forward voltage drop for more efficient forward operation.
o On battery-powered devices, such as PDAs, cell phones, and notebook computers, this
could equate to longer battery life.
! Central Semi CMDSH2-3
o Our B0520WS offers lower forward voltage drop for more efficient forward operation.
o On battery-powered devices, such as PDAs, cell phones, and notebook computers, this
could equate to longer battery life.
o Our B0520WS offers a higher forward surge current rating. This could result in our part
reliably withstanding strong over-current transient conditions which can occur during
unexpected short-duration short-circuit conditions.
! Infineon BAT60B
o Higher BVR may allow customer to use our B0520WS in some higher voltage
applications, where they cannot use Infineon.
o Lower IR may equate to less power consumption and/or longer battery life in some
applications.
