MURA220T3G is a 200V, 2A AEC-Q101 qualified ultrafast rectifier in a surface-mount SMA package. It is designed for high-frequency applications where its 35ns recovery time and low forward voltage are critical for efficiency.

AI replacement insight

Package risklow

The SMA (DO-214AC) package is highly standardized, making physical replacement straightforward.

Electrical riskmedium

Must verify reverse recovery time (trr), forward voltage (Vf), and reverse leakage (Ir). Also confirm if AEC-Q101 qualification is required.

Sourcing risklow

Multiple manufacturers produce 2A ultrafast rectifiers in SMA packages, providing a good supply base.

Can it be replaced directly?

Direct replacement for MURA220T3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

ES2D is the strongest parametric match, offering similar voltage, current, and recovery speed in the same SMA package. It is the most likely candidate for a drop-in replacement.

Main risk

The main risk when substituting is a mismatch in reverse recovery time (trr) or forward voltage (Vf), which can degrade circuit efficiency, increase heat, or cause timing failures in high-frequency applications.
