HSMBJSAC5.0 thru HSMBJSAC50

500 WATT LOW CAPACITANCE

TRANSIENT VOLTAGE SUPPRESSOR

SCOTTSD A L E DIVISION

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.
