Single Zener Diodes FAQ

What does the 'e3' suffix indicate?

The 'e3' suffix indicates that the device is RoHS compliant and features matte tin plating on the terminals.

How is polarity identified on the device?

Polarity is indicated by a band on the cathode end; the diode must be operated with the banded end positive with respect to the opposite end.
