SLVS817G May 2008 – June 2015 TPD4S009 , TPD4S010
PRODUCTION DATA.
TPD4S009 and TPD4S010 are passive TVS diodes and so there is no requirement to power them. They are fully functional without any power supply. However, TPD4S009 does provide an option to apply a DC voltage to its VCC pin, whose purpose is to bias the internal central clamp and insure a known voltage on all internal nodes during startup time. This feature is optional, and whether or not a DC voltage is applied to VCC does not affect the ESD performance of this device.
