From: Winfield Hill on 31 Jan 2010 13:51 Working on a table for our book, soliciting your opinions, info and advice. For example, try these: '3904 ans '3906 = jellybean? MPS5179, PN5179, MMBT5179 -- what's PNP equivalent? BC547 NPN, sot-23 equiv = BC847, right? BC557 PNP, sot-23 = BC857 ? can I just show the C-grade high-beta variant? '2369 ... what's a better type, PNP equiv? and etc... I'm working on two tables, a short one for inclusion within the body of the transistor chapter, and a long one to be placed at the back of the book. Your favorite candidates are solicited. -- Thanks, - Win

BFS17, fast but not too fast. John

Yep, very small die. > BFS17, fast but not too fast. What, no PNP equivalent? I've got BFT92 and BFT93 in the table. How does the BFT25 compare to the BFT92? -- Thanks, - Win |
