Is there a pin-compatible replacement for BAT46WS?

Based on this review, no pin-compatible (SOD-323 package) alternatives have been confirmed. All functional candidates require a different PCB footprint.

What risks should I check before replacing BAT46WS?

The main risk is the physical package. Verify the footprint (SOD-323). Also confirm forward voltage (Vf) and reverse recovery time (trr) are suitable for your application, as these can vary between Schottky diodes.

BAT46WS Alternatives, Datasheet & Cross Reference | Diotec Semiconductor

BAT46WS is a 100V, 150mA Schottky diode in a compact SOD-323 package, used for fast switching and signal rectification. Finding a direct replacement requires matching the Schottky characteristics and the SOD-323 footprint.

AI replacement insight

Package riskhigh

Alternatives found are in different packages (SOD-123, SMA) and are not drop-in replacements.

Electrical risklow

Functionally similar Schottky diodes with matching or better ratings are available if package is not a constraint.

Can it be replaced directly?

No direct pin-compatible replacements were found in this review. Several candidates are functionally similar Schottky diodes but come in different packages (SOD-123, SMA), requiring a board redesign.

Best replacement path

Search for Schottky diodes with Vr ≥ 100V, If ≥ 150mA specifically in the SOD-323 package to find a potential drop-in replacement.

Main risk

The primary risk is package incompatibility. Using an alternative requires changing the PCB layout.

Recommended alternatives

Parametrically similar Schottky diode but in a different SOD-123 package, requiring a board redesign.
