Default Re: Indentifying transistor pinouts with a DMM

Before I got a component analyser I just used to use trial and error. There are only 4 common arrangements, CBE, EBC, BCE and ECB, each as PNP and NPN. If the transistor doesn't give a sensible hfe reading in one of these positions then it's a CEB/BEC HF transistor like an MPSH10, not a bipolar transistor at all, or faulty. Possible CEB types received further attention.

The Chinese analysers do make life a lot simpler though, despite sometimes getting it wrong.
