28. Relay Flyback Diode Selection

✅ Component type/application: This is a single 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: 600V, which exceeds the required ≥40V.

✅ Package: SMA (DO-214AC, SMA), matching the required SMA package.

✅ Mounting type: Surface Mount, matching the requirement.

✅ Operating temperature range: -65°C to 150°C junction, which is wider than the required -40°C to +125°C or wider.

✅ RoHS compliance: Yes (ROHS3 Compliant).

All listed requirements are satisfied. This component is approved for the stated relay flyback diode application.
