It's marked 2L on it.

It's in serie with the 12 volts line.

For the L2 diode , it's not a SOT23 pkg.

L2 or 2L ?

It's a 2 pins diode.

It would help if you traced the circuit. Sometimes designers place a
reverse biased rectifier diode, eg 1n4001, across the input terminals
for reverse polarity protection. An AC input voltage would have short
circuited it.
