DESCRIPTION
APPEARANCE
This SAC5.0 thru SAC50 transient voltage suppressor (TVS) series rated at
500 watts provides an added rectifier element as shown in Figure 4 to
achieve low capacitance in applications for higher speed data or signal
lines.
The low capacitance rating of 30 pF may be used for protecting
higher frequency applications in inductive switching environments or
electrical systems involving secondary lightning effects per IEC61000-4-5
as well as RTCA/DO-160D or ARINC 429 for airborne avionics.
If
bidirectional protection is needed, two SAC devices in anti-parallel
configuration are required as shown in Figure 6.
With their very fast
response time, they also provide ESD and EFT protection per IEC61000-4-
2 and IEC61000-4-4 respectively.
DO-41

FEATURES
APPLICATIONS / BENEFITS
Unidirectional low-capacitance TVS series for
flexible thru-hole mounting (for bidirectional see
Figure 6)
Improved performance in low capacitance of 30 pF
Economical plastic series in flexible axial-leaded

* TVS devices are not typically used for dc power dissipation and are instead operated < V
WM (rated standoff voltage) except for transients that briefly
drive the device into avalanche breakdown (VBR to VC region) of the TVS element. Also see Figures 5 and 6 for further protection details in rated peak
pulse power for unidirectional and bidirectional configurations respectively.
