A likely pin-compatible 1000V, 1A general-purpose rectifier in the same SMA package.
Best Alternatives to MRA4007T3G
MRA4007T3G is a 1000V, 1A standard recovery rectifier in a surface-mount SMA package from onsemi. Finding a substitute requires matching the package, voltage, current, and standard recovery characteristics.
AI replacement insight
Electrical riskmedium
Recovery time mismatch is the main electrical risk.
Package risklow
SMA (DO-214AC) is a standard, widely available package.
Sourcing risklow
Many manufacturers produce similar 1000V, 1A SMA diodes.
Can it be replaced directly?
Direct replacement for MRA4007T3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use a general-purpose 1000V, 1A rectifier in an SMA package, such as the M7 or 1N4007(M7), after verifying standard recovery time from the datasheet.
Main risk
The primary risk is substituting a fast-recovery diode for the standard-recovery target, which can introduce unexpected EMI or circuit behavior.
