Diode Cross Reference

Feb 03, 2005 2 Replies

Greetings,



I currently use 1N4935 from On Semiconductor (formerly Motorola). This is a thru-hole diode categorized as "Fast Recovery". I'm trying to find a surface mount equivalent. I've found a surface mount version with Central Semiconductor, but it is not the same. I don't have a curve trace, so I have no idea what property it is that I need to be exactly the same. I do need 30V minimum. Does anyone know of a good cross for this? I've got everything else in surface mount and this is the last part. I'm so close, but yet so far, ha ha. Any help is appreciated.


Well you probably wouldn't go too far wrong with a possible choice such as the DL4935 by Diodes incorporated. Digikey sells these.

Oh. That is a MELF packaged device, so it loves to roll around and make frequent getaways. From a manufacturing standpoint you might prefer something in SMA or SMB package like the RS1DB also from Diodes inc. and sold by Digikey.
