SMDB712C

BIDIRECTIONAL ASYMMETRICAL TVS ARRAY

ISO 9001: 2015 CERTIFIED

DESCRIPTION

The SMDB712C offers four individual asymmetrical devices in a SO-8 package. The device can be configured for 2

or 4 datalines depending on power level requirements. When connecting four devices in two pairs with a common

ground, the total power per line increases to 1.6kW (8/20µs waveform). In addition, the SMDB712C complies with

level 3 DO-160G Section 22, Waveform 5A, when two external 10 Ohm resistors are connected per dataline.
