DESCRIPTION
ransient voltage suppressor (TVS) series rated at 500
The HSMBJSAC t
Watts provides an added rectifier element as shown in Figure 4 to achieve
low capacitance in applications for data or signal lines. The low capacitance
rating of less than 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.
protection is needed, two HSMBJSAC 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.
