Product Description

The SS54A is a high-performance Schottky diode in a compact SMA package.With a low forward voltage drop (VF ~0.55V @5A) and ultra-fast switching capability, it minimizes power loss and enhances efficiency in high-frequency circuits.Which making it ideal for power supply circuits, reverse polarity protection and high-efficiency applications.

Key Features

  • Package Type: SMA (DO-214AC) – Compact and suitable for high-density PCB designs.
  • Schottky Technology: Low forward voltage drop (typically 0.5V at 5A), reducing power loss.
  • High Current Rating: 5A average forward current capability.
  • Peak Reverse Voltage: 40V, making it suitable for low-voltage applications.
  • Fast Switching: Minimal reverse recovery time, enhancing efficiency in high-frequency circuits.
  • Low Leakage Current: Ensures better performance in power-sensitive designs.
  • Operating Temperature Range: -55°C to +150°C, suitable for various environments.

Typical Applications

  • Power Rectification: Used in switch-mode power supplies (SMPS) and DC-DC converters.
  • Reverse Polarity Protection: Prevents damage from incorrect battery connections.
  • Freewheeling Diode: Protects circuits from voltage spikes in inductive loads (e.g., relays, motors).
  • Solar Panel & Battery Charging Circuits: Efficient energy harvesting due to low voltage drop.
  • Automotive Electronics: Used in power management systems where reliability is critical.

Advantages

Compared to conventional PN-junction diodes, the SS54A offers:

  • Lower power dissipation due to reduced forward voltage.
  • Faster switching speeds, improving efficiency in high-frequency applications.
  • Better thermal performance in compact designs.
