James, here's some short data:

1N457: SI-Di, Uni, 75V, 0,075A, A: 0,2A
~=BA188..190, BAY45, BAY73, 1N484A,...
Uni = General purpose types

1N3880: SI-Di, Gl/S-L, 100V, 6A(Tc=100ø), <200ns
~=BYX 62/800
GI = Rectifier
S = Switching stages
L = Power stages

2N3792: SI-P, NF/S-L, 80V, 10A, 150W, >4MHz, B>50
~=BD546B, BD318, 2N6029..31, 2N6229..31,...
NF = AF applications

Hope this helps.

/Hugo :)

James,
I'm sure that many more diodes can replace the 1N457 and the 1N914A is one of them.

As for the 1N3880, I would consider looking for the same case style, being D0-4, MR751 being 194-04. If this is not a issue, the MR751 is probably a good replacement.

James from malaysia. I can't find a diode and transistor that i want, so if anyone can tell me which other model can be replace for below component, thank you.

1. replace for 1N457
2. replace for 1N3880
3. replace for 2N3792
If you tell us where you will use thses parts I'm sure we will be able to find something. It's possible that some of the parts are very unsensistive when it comes to choice meaning it will work with just about anything.
 
Yes, i building a 12V (variable to 30V) power supply with 12V lead acid battery charger in separate circuit, and combine them up to build 1 complete circuit with battery charger. Still under construction, cause i can't find some component i need. Hmmm.... lately i will attach the schematic diagram on forum for comment.
