Needs validationmedium risk
PESD3V3L1BA-N is the closest 3.3 V SOD-323 bidirectional TVS candidate.
Best Alternatives to DW03D-B-S
DW03D-B-S is a 3.3 V bidirectional SOD-323 TVS diode. Alternatives need pinout, clamp, and surge-rating review.
AI replacement insight
Electrical riskmedium
Best match still has weaker clamp and power.
Package risklow
Kept parts list SOD-323 and 2 pins.
Firmware risklow
No firmware interface.
Sourcing riskmedium
Some lifecycle fields are blank.
Can it be replaced directly?
Direct replacement for DW03D-B-S should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with PESD3V3L1BA-N, then verify pinout, clamp voltage, and surge waveform.
Main risk
Higher clamp voltage or lower surge power can reduce protection margin.
