B16WS
MDD(Microdiode Semiconductor)
Needs validationlow risk
A potential upgrade with higher voltage (60V) and current (1A) ratings in the same SOD-323 package.
Best Alternatives to BAT48WS
Finding a substitute for the BAT48WS, a 40V 350mA Schottky diode in a SOD-323 package, involves checking several pin-compatible and upgraded options. Key considerations include matching the form factor and ensuring the replacement's electrical characteristics, especially the maximum operating temperature, meet your application's requirements.
AI replacement insight
Electrical riskhigh
Lower max operating temperature on many candidates is a critical risk.
Package risklow
SOD-323 is a standard package, and all viable candidates match the form factor.
Sourcing risklow
This is a common diode type with many manufacturers and alternatives available.
Can it be replaced directly?
Direct replacement for BAT48WS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
B16WS is a promising upgrade path, offering higher voltage (60V) and current (1A) in the same package. However, its datasheet must be checked to confirm the operating temperature meets or exceeds the target's 150°C.
Main risk
The primary risk when substituting BAT48WS is thermal performance. The target is rated for 150°C, while many potential replacements are only rated for 125°C. This could lead to premature failure in high-temperature applications.
