Is there a pin-compatible replacement for SS2200?

Yes, SS3200 is a pin-compatible upgrade for the SS2200, sharing the same DO-214AC (SMA) package and pin functions. Other parts like ES2D are also pin-compatible but are functionally different and require review.

What risks should I check before replacing SS2200?

The main risks are electrical. Ensure the replacement is a Schottky diode to maintain low forward voltage and high efficiency. If considering a non-Schottky type, you must verify its forward voltage (Vf) and reverse recovery time (Trr) are suitable for your circuit.

AI replacement insight

Electrical riskhigh

Using a non-Schottky diode can increase forward voltage (power loss) or alter switching behavior (Trr).

Package risklow

The SMA (DO-214AC) package is very common, and many alternatives share the same footprint.

Can it be replaced directly?

Yes, SS3200 from the same manufacturer is a direct upgrade path, offering higher current capability (3A vs 2A) in the same package.

Best replacement path

The best replacement path is to use SS3200, which offers a higher current rating in the same package and technology.

Main risk

The main risk when substituting SS2200 is selecting a non-Schottky diode, which can lead to higher power loss or slower switching speed.

Recommended alternatives

A direct upgrade with a higher 3A current rating from the same manufacturer in the same SMA package.
