A pin-compatible upgrade from the same manufacturer with a higher voltage rating (40V).
Find reliable substitutes for the onsemi MBR0530T1G, a 30V, 0.5A Schottky diode in a SOD-123 package. This guide provides verified upgrade paths and cross-vendor alternatives for your design.
Key parameters are well-matched or improved in top candidates. Vf requires attention.
All candidates use the same standard SOD-123 package.
The part and its substitutes are common and available from multiple manufacturers.
Yes, MBR0530 from vendors like Yangjie is a direct parametric match, and MBR0540T1G is a pin-compatible upgrade.
Upgrade to MBR0540T1G for a higher voltage tolerance (40V) from the same manufacturer, onsemi.
The main risk is ensuring the substitute's forward voltage (Vf) and reverse leakage current (Ir) characteristics are acceptable for the application's efficiency and power budget.
