A pin-compatible Schottky rectifier from onsemi with identical key ratings (30V, 0.5A) in a SOD-123 package.
LMBR0530T1G is a 30V, 0.5A Schottky rectifier in a SOD-123 package. Several pin-compatible alternatives and upgrades are available from manufacturers like onsemi and STMicroelectronics, ensuring supply chain flexibility.
Key ratings are easy to match, but secondary parameters (Vf, Ir, Cj) should be checked for sensitive applications.
SOD-123 is a standard package, ensuring mechanical compatibility.
Yes, MBR0530T3G is a direct, pin-compatible replacement for LMBR0530T1G with the same 30V, 0.5A rating in a SOD-123 package.
The best replacement is MBR0530T3G from onsemi, which is a direct cross with identical key ratings. For more design margin, MBR0540T3G offers a higher voltage rating (40V).
The main risk is selecting a replacement without verifying secondary electrical parameters like forward voltage (Vf) and reverse leakage current (Ir), which can impact circuit efficiency and standby power consumption.
