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