20SQ045 Schottky Barrier Rectifier Diode 20A 45V - Solar Axial Cell Diode R-6 Package for Solar Panel - 3 Pack

20SQ045 Schottky Barrier Rectifier Diode 20A 45V - Solar Axial Cell Diode R-6 Package for Solar Panel - 3 Pack

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.
