What risks should I check before replacing SM360A?

Key risks include voltage margin (ensure the replacement's rating is sufficient), forward voltage (Vf) which affects power dissipation, and reverse leakage current (Ir).

SM360A Alternatives, Datasheet & Cross Reference | LRC

Find the best alternatives for the SM360A, a 60V, 3A Schottky diode in a DO-214AC (SMA) package. This guide reviews pin-compatible and upgraded options.

AI replacement insight

Package risklow

The DO-214AC (SMA) package is standardized, ensuring mechanical compatibility.

Electrical riskmedium

Must verify voltage margin, forward voltage drop (power loss), and reverse leakage current.

Sourcing risklow

This is a common diode type with multiple manufacturers, but check stock for specific MPNs.

Can it be replaced directly?

Direct replacement for SM360A should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

SS36(SMA) for a near-identical match, or SS320 for an upgraded voltage rating.

Main risk

The main risks are ensuring sufficient voltage margin and verifying that secondary parameters like forward voltage (Vf) and reverse leakage (Ir) are acceptable.

Recommended alternatives

A strong alternative with a matching package, voltage, current, and forward voltage.
