✅ Component type/application: This is a single standard rectifier diode, suitable for flyback protection across a 12V relay coil.
✅ Diode type: Standard rectifier / general purpose rectifier (Technology: Standard).
✅ Average rectified current: 1A, which meets the required ≥1A and is well above the 80 mA relay coil current.
✅ Repetitive reverse voltage: 50V, which exceeds the required ≥40V.
✅ Package: SMA (DO-214AC, SMA), matches requirement.
✅ Mounting type: Surface Mount, matches requirement.
✅ Operating temperature range: -65°C to 150°C junction, which is wider than the required −40°C to +125°C.
✅ RoHS compliance: Yes (ROHS3 Compliant).
All required specifications are satisfied. This component is approved for the relay flyback diode application.
