DESCRIPTION
APPEARANCE
The HSMBJSAC t
ransient 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 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. If bidirectional
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.

* TVS devices are not typically used for dc power dissipation and are instead operated < V
(rated standoff voltage) except for transients
that briefly drive the device into avalanche breakdown (V
BR
to V
C
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.
