Description

General part information

1N5946BUR-1-Zener-Diode Series

This surface mountable 1.5 W Zener diode series in the JEDEC DO-213AB package is similar in electrical features to the JEDEC registered 1N5913B through 1N5956B axial-leaded package for 3.3 to 200 V. It is an ideal selection for applications of high density and low parasitic requirements. Due to its glass hermetic qualities and metallurgically enhanced internal contacts, it may also be used for high reliability applications when required by a source control drawing (SCD) or screening in accordance with MIL-PRF-19500 as described in Features below.
