how to find equivalent transistor

Sep 25, 2008 5 Replies

Hi,



I need to replace a 8050 transistor. I found the data sheet on the web but no source to buy one. (NPN TO92 IC 800mA 30V switching/audio, drives a siren pieco) What's a proper way to find an equivalent transistor that's actually available?



Cheers



Tony

These are just "jelly bean" general purpose transistors:

A BC337A looks like it might substitute for it:

Just be careful of the pinout. One is EBC, the other is CBE.

available?

Using some random NPNs from my junk box produced a lot of dead bodies though:-)

I can get a BC337 from Altronics. Will watch pinout:-) Easier than I thought!

Thanks!

You are right. When data sheets where still in books I used to have a book with tables that showed equivalent devices by different manufacturers. I was hoping that the web has something like this to offer. In this case hFE is important. The driving circuit is just 2*4069 inverters in parallel over 100 Ohms. The load is an unknown transformer.

available?

Tried the BC337. Blew up after 20 seconds:-) Was worth a try for $0.35
