SMAXX Series
Note 1. VBR measured after IT applied for 300us, IT=square wave pulse or equivalent
2. Surge current waveform per Fig. 3 and derated per Fig. 2
3. For bi-directional types having V RWM of 10 volts and less, the I R limit is doubled
4. Suffix ‘C’ denotes bi-directional devices. Suffix ‘A’ denotes 5% tolerance devices, no suffix denotes 10%
tolerance devices.
5. All terms and symbols are consistent with ANS/IEEE C62.35
6. Transient Voltage Suppressors (TVS) are devices used to protect vulnerable circuits from electrical
overstresssuch as that caused by electrostatic discharge, inductive load switching and induced lightning.
Within the TVS, damaging voltage spikes are limited by clamping or avalanche action of a rugged silicon pn
junction which reduces the amplitude of the transient to a nondestructive level. See Fig. 7 & Fig. 8
