!
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
!
New Product Announcement - May 2001
o Higher BV
may allow customer to use our B0520WS in some higher voltage
R
applications, where they cannot use Infineon.
o Lower I
may equate to less power consumption and/or longer battery life in some
R
applications.
