SMAXXV
TVS DIODE FOR ESD PROTECTION
SURFACE MOUNT SILICON
ZENER DIODE
DESCRIPTION
The UTC SMAXXV is a single line TVS diode, for ESD
protection.
The UTC SMAXXV is protection in portable electronics
applications.
FEATURES
* 50 Watts peak pulse power (tp=8/20μs)
* Transient protection for data lines to
ESD=8KV (Contact)
EFT=40A (tp=5/50ns)
Lightning=5A (tp=8/20μs)
* Small package for use in portable electronics.
* Suitable replacement for Multi-Layer Varistors in ESD protection
applications.
* Protects on I/O or power line.
* Low clamping voltage.
* Low leakage current.
