Needs validationmedium risk
Panjit BR220 is a plausible SMA Schottky alternative for SS220.
Best Alternatives to SS220
SS220 is a 200 V, 2 A SMA Schottky rectifier. Several close alternatives exist, but pinout and full datasheet limits need review.
AI replacement insight
Electrical riskmedium
200 V equals target; verify VF, IFSM, leakage, and thermal limits.
Package riskmedium
SMA matches, but land pattern and polarity need checking.
Firmware risklow
Discrete diode; no firmware impact expected.
Sourcing riskmedium
External parts need ingestion; one indexed MPN has maker ambiguity.
Can it be replaced directly?
Direct replacement for SS220 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with SS220Q-LTP, then SS220-LTP, after confirming polarity and limits.
Main risk
Same 200 V rating gives no extra voltage margin and pinout is not verified.
