⚙️ Key Features:

• Low Forward Voltage: Typical ~0.5V at 2A, minimizing conduction losses and improving efficiency over standard silicon diodes.

• Higher Voltage Rating: 60V rating provides a good safety margin for 24V and 36V systems, common in industrial controls, robotics, and higher-voltage power supplies.

• Fast Switching: Negligible reverse recovery time makes it excellent for switching frequencies up to several hundred kHz in SMPS.

• Compact SMD Design: Saves board space while handling moderate power levels.

• Reliable Performance: Robust construction suitable for demanding automotive and industrial environments.

📦 Typical Applications:

• DC-DC Converters: Output rectification in 12V, 24V, and 36V buck, boost, or flyback converters.

• Reverse Polarity Protection: In automotive (12V/24V), marine, and industrial control systems where voltage spikes may occur.

• Freewheeling / Snubber Diodes: For inductive loads like relays, solenoids, and small motor drives.

• OR-ing Diodes: In redundant or backup power supply circuits.

• Battery Charging/Discharging Circuits: As a blocking diode in solar charge controllers or battery management systems (BMS).

🔧 Polarity & Mounting Notes:

• Polarity Identification: On the SMA package, the cathode is marked with a white line or stripe on one end. The body marking “SS26” is typically read from the cathode end.

• PCB Footprint: Requires a standard SMA (DO-214AC) land pattern.

• Thermal Management: For continuous operation near 2A, ensure adequate PCB copper area (pads connected to a ground/power plane) for heatsinking. The SMA package can dissipate ~1W with proper board layout.

⚠️ Important Design Considerations:

• Thermal Design: Power dissipation at 2A is approximately P = Vf * I ≈ 0.55V * 2A = 1.1W. The SMA package requires good thermal coupling to the PCB to avoid exceeding the junction temperature. Use thermal vias under the pad if possible.

• Reverse Leakage: Schottky diodes exhibit higher reverse leakage than PN diodes, especially at high temperatures. This may be a concern in very high-impedance or precision circuits.

• Voltage Margin: For reliable operation in 24V systems (with transients), the 60V rating is appropriate. For 48V systems, consider a 100V Schottky (e.g., SS210).

• Current Rating: Ensure your application’s average current does not exceed 2A. For pulsed currents, verify against the IFSM rating and duty cycle.

• Surge Protection: In automotive applications, additional transient voltage suppression (TVS) may be required, as load dump spikes can exceed 60V.
