SMAJ Series 400W SMA DO-214AC TVS Diode is a type of voltage suppressing device that limits over voltages to a safe range to prevent circuit from damaging and has a faster response time than other protection components. This allows TVS to be used in suppressing fast damaging transient voltage, such as lighting, switching, ESD, etc.

The TVS SMAJ SERIES is offered in the industry standard,  SMA package to enable easy solderability.


Application

  • I/O Interfaces

  • VCC bus

  • Telecom base station

  • Military and defense
