In the world of power electronics, finding components that deliver high performance in compact packages is critical. The Diotec SRL23 Schottky Diodes represent a perfect balance of efficiency, reliability, and space-saving design. At Area51 Electronics, we’re proud to offer these exceptional components from Diotec Semiconductor AG, a German-based technology leader with over 6,000 products in their portfolio.

Why Choose the SRL23?

The SRL23 series stands out in the crowded field of Schottky barrier rectifiers for several compelling reasons. These diodes are engineered for applications where space is at a premium but performance cannot be compromised. What truly sets the SRL23 apart is its Power SOD-323 package—not to be confused with standard SOD-323 packages found in competing products. This enhanced package design enables superior heat dissipation and higher power handling in the same compact footprint. Whether you’re designing power supplies, motor control circuits, or protection systems, the SRL23 delivers both the size and the thermal performance modern electronics demand.

Key Technical Specifications

Let’s dive into what makes the SRL23 a standout component:

Note: The SRL23 features a Power SOD-323 package, which offers significantly better heat dissipation and higher power handling compared to standard SOD-323 packages used by many competitors. This is a critical differentiator for high-current applications.

Performance Highlights

Ultra-Low Forward Voltage Drop

One of the SRL23’s most impressive features is its exceptionally low forward voltage drop. At just 0.35 V typical (0.36 V maximum at 125°C), these diodes minimize conduction losses, which translates directly to improved efficiency in your designs. In power-sensitive applications like battery-powered devices or high-efficiency power supplies, every millivolt counts—and the SRL23 delivers.

Power SOD-323: Not Your Standard Package

Here’s where the SRL23 really stands apart from the competition. While many competitors offer standard SOD-323 packages, the SRL23 features a Power SOD-323 package—and that ‘Power’ designation makes all the difference.

The Power SOD-323 is specifically engineered to handle higher power levels and dissipate heat more effectively than standard SOD-323 packages. Despite the same compact footprint and ultra-small profile (weighing just 0.005 grams), the Power SOD-323 delivers superior thermal performance with a junction-to-terminal thermal resistance of just 30 K/W. This enhanced thermal management capability means you can push the SRL23 harder while maintaining reliable operation—a critical advantage in high-current applications where every degree matters.

For engineers working in space-constrained designs, this is a game-changer: you get the footprint of a standard SOD-323 with the power-handling capabilities typically reserved for larger packages. No compromise between size and performance.

Fast Switching for Modern Applications

Schottky diodes are renowned for their fast switching capabilities, and the SRL23 is no exception. This makes them particularly well-suited for switch-mode power supplies (SMPS), flyback converters, and circuits with inductive loads where rapid switching is essential for efficiency and performance.

Real-World Applications

The SRL23 excels in a variety of critical applications:

Flyback and Freewheeling Circuits: Protect motors, relays, solenoids, and actuators from voltage spikes generated by inductive loads. The SRL23’s fast switching and low forward voltage make it ideal for energy recovery in these applications.

Polarity Protection: Safeguard your circuits from reverse battery connections or incorrect power input in both industrial and consumer electronics. The low forward voltage drop minimizes power loss in the protection circuit.

OR-ing Circuits: Enable intelligent power path selection in redundant power supply systems and battery backup configurations. The SRL23’s characteristics make it perfect for applications where multiple power sources need to be managed efficiently.
