    Hi,

    I use "Circuit Wizard" for my prototypes, and currently I'm trying to reverse engineer a circuit with a clearly marked 2N5028 transistor. Unfortunately there isn't one listed in the program's database, and I've searched online for an equivalent but can't seem to find one. Could anyone help here?

    Many thanks

    Dobbies here's the Specs on row 20:)

    Dobbies a Newtone (NTE) 123AP crosses but I say it's always best 2 just use OEM when possible.

    Thank you Aleph.

    I did say that 2n5028 is clearly marked on the case but after looking with a x10 magnifying glass I'm now thinking it's 2n6028.

    Albeit the 2n5028 is on the datasheet you posted, I cannot find any other documentation or pinout details for that model on the web. Whereas the 2n6028 seems quite common but a different animal. Not sure where I'm going with this.

    The 6027/6028 is a programmable unijunction - sort of a SCR with the gate at the other end.

    Dobbies if it's a 2n5028 the pinout is EBC (pins down, flat side facing) and all the other essential specs are in the reference I linked in post 2:) Now if it's a 2n6028, pinout is AGK (pins down, flat side facing) and u can download its data sheet here:cool:

    So hope this helps:)!
