Diode reverse leakage
ℹ infocurrent/diode-leakage
What it looks like
D1 is blocking, but its declared leakage lets ~0.6 µA flow backwards anyway — on a battery, that's a slow drain that never sleeps.
What it checks
When a diode with declared leakage (the datasheet's I_R at V_R) blocks, the solver models that leakage as the real resistance it is and reports the actual backwards current at the solved operating point.
Why it matters
An OFF diode isn't a wall — it leaks, and on battery products the leak runs 24/7. A few microamps of 'blocking' diode can out-drain the microcontroller it protects.
How to fix it
If the number matters, pick a lower-leakage part (leakage varies by orders of magnitude between diode families) or restructure so the reverse path doesn't sit across the battery. If it doesn't matter, you now know that for a fact instead of hoping.
