Hi Jean, thanks a lot for the tip.

The transistor eventually to be replaced is in the vertical final stage of a T935A and the VCeo = 12 V is absolutely fine.

Can I ask you some other advice?

Thank you.

Hi Franco

I just checked for 151-0434-00 as used in a TEK product.

I would recommend to try? 2N2894,? it is a fast PNP switcher originated from SGS Fairchild.

The VCeo is 12 V, so have a look on the schematic of your apparatus? to see if this is enough.

Keep me posted

Hello everybody.

In your opinion, how do you find the commercial equivalent of a transistor signed with the code TECTRONIX for example 151-0434-00?

A thousand thanks.

Hello. FZ

Franco,

I always start with the excellent "TEKTRONIX Semi-Conductor Common Design Parts Catalog". at this link:?
