Although rectifier diodes 1N4007, M7 and A7 are rectifier, what are the differences?

1N4007 in line diode parameters

Packaging form: DO-41

Reverse repetitive peak voltage: 1000V

Average forward current: 1.0A

Forward non repetitive surge current: 30A

Forward peak voltage: 1V

Reverse leakage current (TA = 25 ° C): 5ua

M7 SMD diode parameters

Package form: do-214ac (SMA)

Reverse repetitive peak voltage: 1000V

Average forward current: 1A

Forward (non repetitive) surge current: 30A

Forward peak voltage: 1V

Reverse leakage current: 5ua

A7 chip diode parameters

Package form: sod-123fl

Reverse repetitive peak voltage: 1000V

Average forward current: 1A

Forward (non repetitive) surge current: 25A

Forward peak voltage: 1.1V

Reverse leakage current: 5ua

It can be seen from the parameters that the biggest difference between 1N4007, M7 and A7 lies in the different packaging forms. The forward surge current of A7 is relatively low. At the same time, a7 is smaller and thinner than M7, but it can be directly interchanged in the circuit. 1N4007 is an in-line rectifier diode. If there are no special requirements for packaging, it can also be directly replaced with M7 and A7.
