What risks should I check before replacing SS36?

Key risks include ensuring the replacement has an equal or higher voltage (≥60V) and current (≥3A) rating. Also, confirm the package is the same (SMA/DO-214AC) for a drop-in fit. Finally, check the forward voltage (Vf) to ensure it doesn't negatively impact power efficiency.

Find the best alternatives for the SS36, a 60V 3A Schottky diode in an SMA package. We review upgrade paths and functional alternates to keep your design in production.

AI replacement insight

Electrical risklow

Low if using an upgrade like SS56. High if accidentally selecting a part with lower voltage or current specs.

Package risklow

Low for SS56 (same package). High for alternatives like SS56B (different package).

Firmware risklow

Not applicable for this component type.

Can it be replaced directly?

Direct replacement for SS36 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Upgrade to SS56, which offers higher current (5A vs 3A) in the same SMA package.

Main risk

The main risk is using a part with a lower voltage or current rating. Package mismatch is another key risk that requires a board redesign.

Recommended alternatives

A potential upgrade with a higher current rating (5A) in the same SMA package as the original 3A part.
