SR5200
Yangjie Technology
Needs validationmedium risk
A robust Schottky diode with higher voltage and current ratings in the same DO-201AD package.
Best Alternatives to 1N5401
The 1N5401 is a widely used 3A, 100V general-purpose rectifier in a DO-201AD package. Finding a substitute requires careful matching of its electrical characteristics and package, with special attention to the diode type.
AI replacement insight
Electrical riskhigh
Diode type mismatch (Schottky/Fast vs. General Purpose) can alter circuit performance.
Package risklow
All candidates share the same DO-201AD package, ensuring physical compatibility.
Can it be replaced directly?
No direct, one-to-one replacement is identified. All candidates are different diode types (Schottky or Fast Recovery) and require engineering review before substitution.
Best replacement path
Consider SR5200 for its superior voltage (200V) and current (5A) ratings, but verify its suitability as a Schottky diode in your application.
Main risk
The primary risk is the functional difference between the target general-purpose diode and the Schottky/Fast-Recovery candidates, affecting reverse leakage, forward voltage, and switching behavior.
