Valid provided that electrodes are kept at ambient temperature.
For general purpose applications.
These diodes feature low turn-on volt-
age and high break-down voltage.
These devices are protected by a PN
junction guard ring against excessive volt-
age, such as electrostatic discharges.
This diode is also available in the DO-35 case
with type designation BAT48.
