Transistor data with sorting

Greg Erskine · 18th June 2010, 10:18 PM

I have been thinking of this idea for years and really expected to find it had already been done. Most of us probably have a spreadsheet that we half maintain.

I really wanted a simple table of transistors we commonly use in DIY audio and have the table sortable by various parameters. I seem to be always checking (and rechecking) the data sheets for say, lead order when substituting parts. This little table of transistor data should save me time and effort. I plan to exand the data for NPN, VAS, driver and output transistors.

Feedback welcome.

PNP Small Signal Transistors

BTW: I use IE and don't know about cross browser support.

It works using Firefox.

Hi Greg,

It works on Safari and Firefox on Mac, too. Thanks for the table! It will grow, right? Do you want some contribution for the tr specs? How about JFETs? MOSFETs?

Best regards,

link to a datasheet?

looks good

Hi satoru,

Thanks for the feed back on Safari and Firefox.

It will grow, it already has.

Yep, make any suggestions for transisitors I need to add.

Also, I need some guideance on what specs are important for transistors for particular roles. Like the VAS needs to have atransistor with low Cob, I think.

I will add any groups that are popular including JETs and MOSFETs.

regards

Hi johnferrier,

I was thinking about links to datasheets, but there are a few issues like, the online ones I use, I can't link directly to and the manufactures don't always have datasheets for old components. I will think further on this as links are a PITA to maintain.

I will smarten the appearance over time. I just wanted to get something simple working and see if I liked it and if it was of interest to others.

Thanks for the feedback on Chrome.

regards
