Is there a pin-compatible replacement for SS36B?

Yes, SS56B and SS510B are pin-compatible replacements in the same SMB package with equal or better electrical ratings. SL26B-TP is also pin-compatible but has a lower current rating, which requires careful review.

What risks should I check before replacing SS36B?

Before replacing SS36B, check three key things: 1) The package must be DO-214AA (SMB) for a drop-in fit. 2) The replacement must be a Schottky diode, not a standard rectifier. 3) The voltage and current ratings must be at least 60V and 3A, respectively.

SS36B Alternatives, Datasheet & Cross Reference | Microdiode Semiconductor (Shenzhen) Co., Ltd.

SS36B is a popular 60V, 3A Schottky rectifier in a DO-214AA (SMB) package, used for high-efficiency applications. Several pin-compatible upgrades and functional alternatives are available from various manufacturers.

AI replacement insight

Package riskhigh

Many similar MPNs exist in different (SMA/SMC) packages. Verify the package code (DO-214AA) carefully.

Electrical riskmedium

Ensure the replacement is a Schottky diode and not a general-purpose type. Check current and forward voltage ratings.

Sourcing risklow

This is a common diode type with multiple manufacturers and good availability.

Can it be replaced directly?

Yes, SS56B is a potential direct replacement with an improved current rating. Always verify the forward voltage drop (Vf) meets your application's efficiency needs.

Best replacement path

SS56B offers an easy upgrade path with a higher 5A current rating in the same SMB package, providing additional design margin.

Main risk

The main risk is selecting a part with a different package (e.g., SMA, SMC) which requires a board respin, or a non-Schottky diode type, which would cause functional failure.

Recommended alternatives
