component
MBR140ESFT1G
Public Made by Adomby adom
onsemi Schottky Diodes, SOD-123. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

metal−to−silicon power diode. Ideally suited for low voltage, high
frequency rectification or as free wheeling and polarity protection
diodes in surface mount applications where compact size and weight
are critical to the system. This package also provides an easy to work
with alternative to leadless 34 package style. Because of its small size,
it is ideal for use in portable and battery powered products such as
cellular and cordless phones, chargers, notebook computers, printers,
PDAs and PCMCIA cards. Typical applications are AC−DC and
DC−DC converters, reverse battery protection, and “Oring” of
multiple supply voltages and any other application where performance
and size are critical.</rdf:li>+ </rdf:Alt>+ </dc:description>+ <xmp:CreateDate>2014-02-18T15:43:39-07:00</xmp:CreateDate>+ <xmp:CreatorTool>BroadVision, Inc.</xmp:CreatorTool>+ <xmp:ModifyDate>2020-10-05T11:02:49+02:00</xmp:ModifyDate>+ <xmp:MetadataDate>2020-10-05T11:02:49+02:00</xmp:MetadataDate>+ <pdf:Producer>Acrobat Distiller 9.5.5 (Windows)</pdf:Producer>+ <xmpMM:DocumentID>uuid:6d02b8bd-a6de-46a6-a107-1d21e9122b9b</xmpMM:DocumentID>+ <xmpMM:InstanceID>uuid:7b066114-0a72-41fe-9006-da6cee0068d5</xmpMM:InstanceID>+ <illustrator:StartupProfile>Print</illustrator:StartupProfile>+ </rdf:Description>+ </rdf:RDF>+</x:xmpmeta>+ + + + + + + + + + + + + + + + + + + + + +<?xpacket end="w"?> +endstream+endobj+4 0 obj+<<+/Nums [4 12 0 R 5 13 0 R]+>>+endobj+6 0 obj+<<+/Contents [14 0 R 15 0 R 16 0 R 17 0 R 18 0 R 19 0 R 20 0 R 21 0 R]+/CropBox [0.0 0.0 612.0 792.0]+/MediaBox [0.0 0.0 612.0 792.0]+/Parent 2 0 R+/Resources 22 0 R+/Rotate 0+/Type /Page+>>+endobj+7 0 obj+<<+/Annots [23 0 R 24 0 R 25 0 R 26 0 R 27 0 R 28 0 R]+/Contents 29 0 R+/CropBox [0.0 0.0 612.0 792.0]+/MediaBox [0.0 0.0 612.0 792.0]+/Parent 2 0 R+/Resources 30 0 R+/Rotate 0+/Type /Page+>>+endobj+8 0 obj+<<+/Contents 31 0 R+/CropBox [0.0 0.0 612.0 792.0]+/MediaBox [0.0 0.0 612.0 792.0]+/Parent 2 0 R+/Resources 32 0 R+/Rotate 0+/Type /Page+>>+endobj+9 0 obj+<<+/Contents 33 0 R+/CropBox [0.0 0.0 612.0 792.0]+/MediaBox [0.0 0.0 612.0 792.0]+/Parent 2 0 R+/Resources 34 0 R+/Rotate 0+/Type /Page+>>+endobj+10 0 obj+<<+/Contents [35 0 R 36 0 R 37 0 R 38 0 R 39 0 R 40 0 R 41 0 R 42 0 R]+/CropBox [0.0 0.0 612.0 792.0]+/MediaBox [0.0 0.0 612.0 792.0]+/Parent 2 0 R+/Resources 43 0 R+/Rotate 0+/Type /Page+>>+endobj+11 0 obj+<<+/Annots [44 0 R 45 0 R]+/Contents 46 0 R+/CropBox [0.0 0.0 612.0 792.0]+/MediaBox [0.0 0.0 612.0 792.0]+/Parent 2 0 R+/Resources 47 0 R+/Rotate 0+/Type /Page+>>+endobj+12 0 obj+<<+/S /D+>>+endobj+13 0 obj+<<+/S /D+>>+endobj+14 0 obj+<<+/Length 872+/Filter /FlateDecode+>>+stream +H��TM��6zԯ��T��$E�(z�l6H�M�k�=9he�f"K^J^���R��N/-[�0|�͛7$��w ���pB�=0+���+PX$���V=�8H����Aa�*E��Po��M"#���&�'&7er}ǰ�\&2�H��HQ(�5ɹPn++��u��'�/Y�-�.K>d�J��ly�JY�`n7���Ů:o�Ͷkm;�����w�����\�LL�b��Q�>i�*�A�,P� &��Y ����'���!Ӝ�t���k�!��#�"�3=�|��wJ��v�2cY������Ѿd���#��6ƌ��O�Ofi��� ~�%��V҇�S��jp]���z���<Y�ۥC��̐�(�O��7�Lз���x��D>�CO��AqA-dpv��p16{B���@g?=f̤�L�C�o��9A��+lP \�B*"�o���=K���S���h^�F�+N4���Ɛ�[��&Y�1��h�Z=��l��.���}�k�(�F�bs1�f�|^��a�~��n�~?�zpKg�����A�j��<7�X�S,Y>β����0�|;aMQ,�,L������ �������{����4�Q#�&��Q��ӰBG��1�ӄ˵�aa_:��m���ɑ���z�z��n�Xػa 4��pt&]Y�����3� R���G��5�;T�$�%�*)ά8wA](�6&�Cw��#1����� ���P��/�$#���X�na �_تi���`�������5N�+�n�x3�^���ҥ��;�ևL����M���UX����m\���]��C��p�L�[� �P�F��_1���=J�3\�\�R}܅M������|o�������������G� �c�M +endstream+endobj+15 0 obj+<<+/Length 779+/Filter /FlateDecode+>>+stream +H��T���0��+映��'M$���Z�+�+� q��6lG�Ӫ���>�����b�Ǚ�7�ޛ@u=�^L�,�j7� -!��dպ�M-��ժ�a-�썕պ1Ћ�A�K�Q�k�m�Ҁ�@+���)�A(+SFXIk1�"jU��������:Ie�CH���H�V�N�f+]�V�e+����ݷ��Y��HP+h��m��&/\�i(���B]}�h22�X��p}�4�ZM��Vܵ8f��;a��=^K7�r��P�A?-��� �<
