AI replacement insight
Electrical riskmedium
VF, IFSM, and recovery may differ.
Package risklow
Most candidates are SMA/DO-214AC.
Firmware risklow
Discrete diode, no firmware.
Sourcing riskmedium
Some records have source or lifecycle gaps.
Can it be replaced directly?
No fully verified drop-in replacement is confirmed from the provided fields.
Best replacement path
Review M7 or MRA4007T3G first, then verify datasheet pin polarity and stress ratings.
Main risk
Pin polarity and surge/VF differences are not fully verified.
