Title: Can you Identify this Diode?
Post by: Lost Electron on April 12, 2021, 11:03:04 pm

Hello everyone,
I am repairing a HP4263A LCR meter which has burned input protection diodes. I searched the number on these diodes but I was not successful in finding definitive information.
The number on the diode is: T771-H
I attached a drawing of the diode with the numbers as they appear on the diode. This diode might be a BYT77 but I am not sure. Your help is greatly appreciated. Thanks!
