The recovery time of the Hamamatsu SiPM linear assembly was measured. The assembly contains eight SiPMs of 2.8mm active area diameter; pixel size is 15xl5mkm 2 . The assembly is used for Phase1 upgrade in hadron calorimeter of the CMS experiment. Recovering process is found to depend on the number of the pixels fired and varied from 7 ±1 ns to 23 ± 3 ns for 50 Ohm readout impedance.
