Is there a pin-compatible replacement for SK36A-LTP?

Yes, SK310A-LTP and SK38A-LTP use the same SMA (DO-214AC) package and are expected to be pin-compatible. However, always verify the datasheet's recommended land pattern before finalizing your design.

What risks should I check before replacing SK36A-LTP?

Ensure the replacement is a Schottky diode in an SMA package with at least 60V reverse voltage and 3A average forward current. Avoid standard rectifiers, parts in different packages like SMC, and those with an 'Obsolete' or 'NRND' lifecycle status.

SK36A-LTP Alternatives, Datasheet & Cross Reference | Micro Commercial Components Corp.

SK36A-LTP is a 60V, 3A Schottky rectifier in a common SMA package. When seeking alternatives, prioritize parts with the same or higher voltage, same current, and matching SMA (DO-214AC) package.

AI replacement insight

Electrical risklow

Low risk if replacement is a Schottky diode with >=60V and >=3A ratings.

Package riskmedium

Many similarly named but physically different packages exist. SMA/DO-214AC must be verified.

Sourcing risklow

The target part is active and has readily available upgrades within the same family.

Can it be replaced directly?

Yes, SK310A-LTP is a strong candidate for direct replacement, offering improved voltage margin with an active lifecycle.

Best replacement path

Upgrade to SK310A-LTP for a higher 100V rating in the same package from the same manufacturer.

Main risk

The primary risk is selecting a part with a different package (e.g., SMC, SOD-123) or a non-Schottky diode, which would impact performance and require board redesign.

Recommended alternatives

A 100V, 3A Schottky diode in the same SMA package, offering a higher voltage margin.
