20SQ045 Schottky Barrier Rectifier Diode
Key Features
- Part Number: 20SQ045
- Technology: Schottky Barrier Rectifier
- Forward Current (Io): 20A
- Maximum Repetitive Peak Reverse Voltage (Vr): 45V
- Low Forward Voltage Drop (Vf): 0.55V @ 20A
- Package: R-6 Axial
- Mounting Type: Through Hole
- Characteristics: Low power loss, high efficiency, low leakage current
- Compliance: Lead-Free / RoHS Compliant
Replaces / Cross-Reference Part Numbers
- Direct replacement for diodes marked 20SQ045.
- May substitute for other Schottky diodes with equivalent electrical specifications (20A, 45V) and physical package (R-6 Axial). Verify circuit requirements before substitution.
Compatibility & Fitment
- Designed for low-voltage, high-frequency inverters, free-wheeling diodes, and polarity protection applications.
- Commonly used as a blocking or bypass diode in solar panel junction boxes and DC power systems.
- The R-6 axial package is intended for through-hole mounting on a printed circuit board (PCB) or for point-to-point wiring.
When to Replace
- Component tests as a short circuit, allowing current to flow in both directions.
- Component tests as an open circuit, blocking current flow in the forward direction.
- Associated fuse or circuit protection device repeatedly fails.
- Noticeable decrease in circuit voltage output or efficiency.
- Visible signs of overheating, such as discoloration or damage to the component body.
Installation Tips
- Observe polarity. The stripe on the diode's body indicates the cathode (negative) lead. Incorrect installation will cause circuit failure.
- When soldering, use a heat sink on the lead between the component body and the solder joint to prevent heat damage.
- Avoid bending leads too close to the diode body to prevent stress on the internal seal.
- Ensure sufficient clearance and airflow around the component for heat dissipation, especially in applications approaching the 20A current rating.

Bad fit
Style: C20 Parts * 19pcs
The dust bags do not fit properly. You can get the base to acknowledge them if you place them just right, but any little movement can move them out of place. I have to constantly reseat them because the base thinks there is no bag. The stock bags do not have this problem.
Edit: It has gotten to the point where it is constantly flipping between registering and not registering the bag. Changing to 1 star because they are unusable. If I'm not there to fix it, the task fails every time.

Not compatible with eufy Omni C20.
Style: C20 Parts * 19pcs
The filters are too small. To avoid dust laden air from just going around them I put pieces of paper around the edges as spacers. But they're also shorter too. No chance of a reasonable seal.
Then the vacuum bags are the wrong size too. The robot gives me an error message saying "no vacuum bag is detected". The mop still works, but no vacuum action.
I only bought this kit because the one I was using (that works) was temporarily unavailable.
Never again.
