It's not critical part, you can use any rectifier diode you find,
from 1N400x family (1N4001,1N4004...), but _do not_ use small
signal diodes like 1N4148. It's in there to protect the circuit
from wrong _polarity_ (not voltage) by coducting. You obviously
applied wrong polarity. It should have survived (that's why
you should use stronger diode).
