Finding a substitute for the BAT54T1G, a popular 30V 200mA Schottky diode, involves matching the SOD-123 package and verifying key electrical parameters. Several functional alternatives exist with similar or better ratings.

AI replacement insight

Electrical riskmedium

Vf, Ir, and trr must be verified. A mismatch can cause power loss or signal integrity issues.

Package risklow

Multiple candidates are available in the same SOD-123 package, ensuring physical compatibility.

Can it be replaced directly?

There are several functional alternatives for BAT54T1G in the same SOD-123 package. No verified pin-to-pin drop-in is confirmed without a datasheet review of key electrical parameters.

Best replacement path

Select a candidate with a matching SOD-123 package and voltage/current ratings greater than or equal to 30V/0.2A. STPS0540Z and SL02-GS08-FS are strong starting points.

Main risk

The primary risk is a mismatch in forward voltage (Vf), reverse leakage (Ir), or dynamic characteristics like recovery time (trr) and capacitance (Ct), which can affect circuit efficiency and high-speed performance.
