Convert string to date in SSIS

Hi Team, 

I have a string value from a file which is in the below format: 

dd-mmm-yy

01-jan-15

03-sep-19

Which are to be in this format in the destination: 

yyyy-mm-dd

2015-01-01

2019-09-03

Please help me if there is any SSIS expression to do so in derived column component. 

Thanks,

Vikram
