SM8LC05 - SM8LC24
800 WATT MULTI-LINE TVS ARRAY
DESCRIPTIoN
The SM8LCxx Series are high powered transient voltage suppressor arrays that provides board level protection for
standard TTL and MOS bus line applications against the damaging effects of ESD, tertiary lightning and switching
transients.
The SM8LCxx Series has a peak pulse power rating of 800 Watts for an 8/20µs waveshape. This device series meets
the IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.

1. Devices are designed to be used in parallel. For other applications, contact the factory. Do not surge in the “forward” direction of the TVS.
2. Do not surge from pins 1 to 8, 7 to 2, 6 to 3 and 4 to 5. PIV typically greater than 100 Volts for each rectifier diode.
