WEET M7 SMA DO 214AC 1A 1000V Diode M4 M5 M6 Replacement Made in China

Fri, 20 May 2022 10:17:20 +0800

M7 is the SMA DO-214AC package of 1N4007.

It is an ordinary rectifier diode with withstand voltage of 1000V and maximum average forward rectified
current of 1A. Commonly used in AC220V rectifier circuit.

What can be used to replace rectifier diode M7?
What are the parameters of chip diode M7 and what tube can be used to replace it?
What types of diodes are M7 SMD diodes common to?
What is the difference between chip rectifier diode M7 and A7?

Rectifier diodes can be made of semiconductor germanium or silicon.
M7 and A7 are silicon rectifier diodes with unidirectional conductivity, high breakdown voltage, low reverse leakage current
and good high temperature performance. Generally speaking, the rectifier diode with high reverse voltage can replace the rectifier diode
with low reverse voltage, and the diode with high rectifier current value can replace the diode with low rectifier current value.
For example, M7 diodes can replace M6, M5, M4, m3, M2 and M1, and A7 patch diodes can replace A6, A5, A4, A3, A2 and A1.

The difference between chip diode M7 and A7 is as follows:

Detailed parameters of SMD M7 diode
Package form: do-214ac (SMA)
Average forward current: 1A
Reverse repetitive peak voltage: 1000V
Forward (non repetitive) surge current: 30A
Forward peak voltage: 1V
Reverse leakage current: 5ua, 50ua
Junction temperature: - 55 ° C to + 125 ° C
Storage temperature: - 55 ° C to + 150 ° C

Detailed parameters of chip A7 diode
Package form: sod-123fl
Average forward current: 1A
Reverse repetitive peak voltage: 1000V
Forward (non repetitive) surge current: 25A
Forward peak voltage: 1.1V
Reverse leakage current: 5ua, 50ua
Junction temperature: - 55 ° C to + 150 ° C
Storage temperature: - 55 ° C to + 150 ° C

Difference between diode M7 and A7

It can be seen from the above parameter details that the biggest difference between M7 and A7 lies in the packaging form.
The diode M7 package is SMA / DO-214AC, the diode A7 package is sod-123FL, and the volume of M7 is larger than A7.
The forward non repetitive surge current of M7 is 5A larger than that of A7, and the junction temperature difference is 5 ° C.
The main difference between M7 and A7 is the packaging form. In practical application, diodes M7 and A7 can replace each other!
