Re: testing a 2sd1525 darlington ?
See diagram called " Equivalent Circuit" .
With your DMM on ohms, testing from B to E in either direction should read
2100 ohms ( +/- 15%).
With your DMM on " diode test", the C- E diode should tests like any
silicon diode with a very high resistance ( Mohms) in the reverse direction.
If all that is OK, the devise is likely OK.
Unless you bought a fake.
