Silicon Switching Diode
PRODUCT PREVIEW
DESCRIPTION
These silicon switching diodes are
available in DO-35 glass packages and
LL4938 Mini-Melf (DO-213AA).
These devices are used in general-
purpose applications where high voltage
and switching speed are important.
When ordering Mil-PRF-19500/169
parts, use the number with the
appropriate 1N4938-1 JAN, JTX or
JTXV prefix.
