BA3430S / BA3430F / BA3430FS

FThermal derating curves

As the allowed power dissipation of the BA3430F /

BA3430FS is small (BA3430F = 550mW, BA3430FS =

800mW), high temperature or high current may cause

the allowed power dissipation to be exceeded. Fig. 8

shows the internal power dissipation vs. supply voltage

can be obtained from these curves, and the result is

shown in Fig. 10. Refer to Fig. 10 to set the supply voltage

when designing the application.
