ST Diode Identification

I’m trying to identify the ST diode shown below, but I haven’t been able to track it down. Is someone more familiar with their product lines than me able to identify it?

Hi jachaulk,

The closest that could find is SM6T27A.

(The “EP” is the marking, “GP013” is the mfg location, year and week).

However, it is a bit strange to place a TVS diode between LDO’s output and input as typically a normal rectifier suffices, so it is somewhat possible that the device is not the one suggested above.
