✅ Diode type/application suitability: The selected 1N4148W-7-F is a small-signal switching diode and is appropriate for signal switching and logic isolation use.
✅ Average rectified current: 150mA specified, which meets the ≥150mA requirement.
✅ Repetitive reverse voltage: 100V specified, which exceeds the ≥75V requirement.
✅ Reverse recovery time: 4ns specified, which is better than the ≤10ns requirement and supports fast logic switching.
✅ Package: SOD-123 specified, which matches the required package.
✅ Mounting type: Surface Mount specified, which matches the requirement.
✅ Operating temperature range: -55°C to 150°C junction specified, which is wider than the required -40°C to +125°C range.
✅ RoHS compliance: ROHS3 Compliant, which satisfies the requirement.
All listed requirements are satisfied, so this component is approved for the stated signal switching diode application.
