The _E suffix commonly denotes an English-language edition of a Japanese maker document; no manufacturer is named. It should detail ratings, hFE ranks, marking and package outline. Use it to identify leads before diode-mode testing and to confirm a substitute has adequate voltage, current and power margins.
