Detailed Technical Specifications

1. Voltage and Current Capabilities

• Voltage - DC Reverse (Vr) (Max): 75 V
  This robust diode can handle reverse voltages up to 75 volts, ensuring reliable operation in diverse electronic environments.

• Current - Average Rectified (Io): 300 mA (DC)
  The 300 mA current rating makes it suitable for low-power applications where efficiency is paramount.

2. Forward Voltage and Leakage Performance

• Voltage - Forward (Vf) (Max) @ If: 1 V @ 300 mA
  With a forward voltage drop of just 1 volt at 300 mA, the 1N4148WS minimizes power dissipation, enhancing overall circuit efficiency.

• Current - Reverse Leakage @ Vr: 2.5 A @ 75 V
  The ultra-low reverse leakage current of 2.5 microamperes ensures minimal energy loss, even under maximum reverse voltage conditions.

3. High-Speed Switching Performance

• Speed: Fast Recovery 500 ns, > 200 mA (Io)
  The diode's fast-recovery characteristics make it ideal for high-frequency applications, reducing switching losses significantly.

• Reverse Recovery Time (trr): 4 ns
  An impressively short reverse recovery time of 4 nanoseconds ensures optimal performance in high-speed switching circuits, such as those found in digital communications.

4. Low Capacitance for High-Frequency Applications

• Capacitance @ Vr, F: 2 pF @ 0 V, 1 MHz
  The diode's low capacitance of 2 picofarads minimizes signal distortion, making it perfect for RF and high-frequency digital circuits.

5. Robust Operating Temperature Range

• Operating Temperature - Junction: -65 C ~ 100 C
  Designed to perform reliably in extreme conditions, the 1N4148WS operates seamlessly across a broad temperature spectrum, from freezing -65 C to scorching 100 C.

6. Compact and Efficient Packaging

• Package / Case: SC-90, SOD-323F
• Supplier Device Package: SOD-323
• Mounting Type: Surface Mount
  The SOD-323 package is not only compact but also compatible with automated PCB assembly processes, streamlining production and reducing costs.

Wide-Ranging Applications

The 1N4148WS diode is a versatile component used in numerous applications, including:

• Signal Switching: Ideal for digital logic circuits and signal routing.
• Flyback Diodes: Protects circuits from voltage spikes caused by inductive loads.
