In high-efficiency power supplies and high-speed switching circuits, the performance of rectifier diodes is crucial. The ES1D is an ultra-fast recovery rectifier diode featuring rapid recovery time and low power consumption, delivering outstanding performance across various applications.
Compared to traditional rectifier diodes, the ES1D offers a much faster reverse recovery time, reducing energy losses and improving circuit efficiency. In high-frequency applications such as DC-DC converters, flyback power supplies, and power inverters, it effectively minimizes switching losses and optimizes overall power management.
Cathode – The negative terminal, marked with a band on the diode body.

ES1D Test Circuit
The ES1D comes in a DO-214AC (SMA) package, which is a compact, surface-mount design perfect for space-saving PCB layouts. This package offers excellent thermal performance and high reliability for high-speed switching applications.
The cathode is usually marked with a stripe on the diode body. When placing it in a circuit, make sure the cathode connects to the negative (output/load) side, and the anode connects to the positive (input/power source) side.
Next, solder the ES1D onto the PCB. Use appropriate heat dissipation methods, such as adding a heat sink or designing proper PCB traces, to handle the 1A forward current and minimize heat buildup. After installation, test the circuit with a multimeter to check for correct voltage drop.
If you're looking for alternatives to the ES1D, several other diodes in the same ES1 ultra-fast recovery series offer similar performance with slight variations in voltage ratings. Some good options include ES1A, ES1B, ES1C, ES1E, ES1G, and ES1J. These diodes share the same DO-214AC (SMA) package and ultra-fast recovery characteristics, making them suitable drop-in replacements depending on your voltage and current requirements.
