Hi i'm trying to repair Cisco EA4500 wifi device which was not powering up, I found that an SMD DIODE with the code Z16 is short. I understood it is being used as overvoltage protection circuit and it is 16 volt zener diode. My problem is i'm not sure which capacity of watt of diode should i use because i replaced with 15 volt - 1 watt (1N4744) diode which should work but it is overheating and short circuiting the board. can someone please suggest the right capacity of diode that i should use.
for info:
1). Adapter rating is 12 volts 1 Amps.
2). Device works well without the diode. ( still I would like to have that protection diode).
3). I'm not finding SMD diode Z16 in market.
