HarryA Posted June 3, 2020 Report Share Posted June 3, 2020 what is the replacement for the d13005ed? Perhaps the MJE13005G ? The data sheet is online. The MJE13005G from China see: https://www.ebay.com/itm/5PCS-X-UTC-MJE13005G-C-TM3-T-TO-251-I-PAK-NPN-Vceo-700V-Ic-4A-Transistors/333530195913? hash=item4da7f2e7c9:g:9MgAAOSwr9ReWXce The D23005Ed 20 of them! "20 x D13005ED Transistor TO-220" from China. https://www.ebay.com/itm/20-x-D13005ED-Transistor-TO-220/184022252029?hash=item2ad894b9fd:g:cLQAAOSwOFZdwBIz also see for large list of similar transistors: https://alltransistors.com/crsearch.php?at=Si&struct=NPN&pc=65&ucb=700&uce=400&ueb=9&ic=4&tj=150&ft=4&hfe=15&caps=TO220 Quote Link to comment Share on other sites More sharing options...
Olaniyi Oladipo Posted June 28, 2020 Report Share Posted June 28, 2020 I have a problem using lm7812 it produced output voltage I connected 48v battery as input voltage but this 12v output didn’t carry just dc fan please what’s the solution to this problem but I remember I do not filter this terminals Quote Link to comment Share on other sites More sharing options...
HarryA Posted June 28, 2020 Report Share Posted June 28, 2020 48 volts is above the absolute voltage for this voltage regulator: 35 volts maximum: Quote Link to comment Share on other sites More sharing options...
Zaldy Macayan Posted September 15, 2020 Report Share Posted September 15, 2020 Hello. Can someone kind enough please provide info about transistor substitute of BC807W and BC817W in TO92 package? They are not locally available but I was hoping a TO92 substitute would be. Will appreciate greatly any reply. Kind regards... Quote Link to comment Share on other sites More sharing options...
HarryA Posted September 15, 2020 Report Share Posted September 15, 2020 see: https://www.nteinc.com/semiconductors/ComplPr.php They list matched complementary pairs that maybe helpful like the NTE128/NTE129 at 80 volts and 1 ampere. And many others as well. Zaldy Macayan 1 Quote Link to comment Share on other sites More sharing options...
Sekemiat KE Posted February 10, 2022 Report Share Posted February 10, 2022 hello 2SD613 NPN replacement is BD243C 2SD633 replacement BD649 2SD600 has replacement BD139 2SB631 has replacement BD140 Quote Link to comment Share on other sites More sharing options...
