Response By EW AI
✅ Diode type: suitable for small-signal switching. DigiKey lists Speed as Small Signal <= 200mA (Io), which matches the required small-signal switching application.
✅ Average rectified current: 200mA, which meets the requirement of ≥150mA.
✅ Repetitive reverse voltage: 100V, which exceeds the required ≥75V.
✅ Reverse recovery time: 4ns, which is faster than the required ≤10ns and is appropriate for logic signal isolation.
✅ Package: SOD-123, exact match.
✅ Mounting type: Surface Mount, exact match.
✅ Operating temperature range: -55°C to 150°C junction, which is wider than the required -40°C to +125°C or wider.
✅ RoHS compliance: Yes, listed as ROHS3 Compliant.
All required specifications are satisfied, so this component is approved for the stated signal switching and logic isolation task.
