Hi Infineon,

I need to protect the Vbus line in a consumer device. Surge protection, prefer leadless package, working voltage should not exceed 15V.

Thanks for your suggestions.

Thanks,

U.

Hi Uwe,

Thanks for your interest in Infineon Products?

I cannot see from your question what protection rating do you need. Is there any particular specification?

In the meantime, I suggest you to look at ESD24VL1B-02LS (0201 TSSLP package) or -02LRH (0402 TSLP package). It provides following protection levels:
– IEC61000-4-2 (ESD): ±20 kV (air), ±18 kV (contact)
– IEC61000-4-4 (EFT): 40 A (5/50 ns)
– IEC61000-4-5 (surge): 1 A (8/20 μs)

Even better protection is achieved by ESD24VS2U:
– IEC61000-4-2 (ESD): ±30kV (air / contact)
– IEC61000-4-4 (EFT): 80 A (5/50 ns)
– IEC61000-4-5 (surge): 5 A (8/20µs)
However, it's in SOT-23 package.

Best regards
Anton
