25 to 101 mm provides transient voltage suppression in
the range of 15kV to 50kV.
Applications
• Drives/Inverters
• Galvanic insulation on one single PCB
• Medium Voltage Power Distributions
• Regulated Distribution Transformers
• Smart Grid on-board Insulations

Recommended chemicals for Cleaning/Degreasing
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptanes
Other: soap solution, naphtha
Do not use partially halogenated hydrocarbons such as 1.1.1 trichloroethane, ketones such as MEK, acetone, chloroform,
ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, Avago does not recom-
mend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.
The Rx Data_out signal is inverted which means that light_on will lead to Data_out low.
POR remains active during VCC power up, typically until 100µs after 2.8V is reached. POR follows VCC while active.
