That is the current should always flow from the Anode to cathode. 99. 0 from the datasheet looks like the shouldn't.... At my Radio Shack anyways, they have a diode assortment pack that has a bunch of different diodes (including a 1n4001) that is just a bit more expensive than the 5 pack of just the 1n4001's. If I were you, I'd use 1N4004 or higher. You may want to check that out if you haven't, its like a 15 pack or something. I'm building this power supply circuit http://imgur.com/10e1zKh it has 1N4001s, my local radioshack doesn't have them, only 4007s, from the datasheet I can see the only difference between the various 400x is the reverse voltage, but I see the 4001 has an RMS Vr of only 35v, meaning it will breakdown in the bridge rectifier (220V RMS), theoretically rendering it useless...am I right? g��w�N���o-�ڇ�a��ï9'Tq�C@>p݄��¾�k�vv�)��͎~;P������O/� �睝�XcӍ��g��ԋ��GDh�h��Ӽ�U�[_曪.�MחGT��z��*<4{�l~���.-'��*�I���7���,�/ū,�4(��!U�;��[��R����&�$�Mj�Pߖ ���p���g��(ugD�2�=z���О���Ρ �vϤ����?5 �+v܀�����_�a��O�ט��cg��^�F���c����W��\���T=ӢiU�����N��C1�80A��|�#� W:�r I'm building this power supply circuit http://imgur.com/10e1zKh it has 1N4001s, my local radioshack doesn't have them, only 4007s, from the datasheet I can see the only difference between the various 400x is the reverse voltage, but I see the 4001 has an RMS Vr of only 35v, meaning it will breakdown in the bridge rectifier (220V RMS), theoretically rendering it useless...am I right?
