## SD103AW-CC2-R: Electronic Specifications and Details The **SD103AW-CC2-R** is a high-speed **Schottky Barrier Diode** housed in a small surface-mount package. It is primarily designed for low-voltage applications requiring fast switching and low forward voltage drops. --- ### 1. General Specifications The following table summarizes the key electrical and physical parameters of the device: | Parameter | Specification | | :--- | :--- | | **Component Type** | Schottky Barrier Diode | | **Package / Case** | SOD-123 | | **Maximum Repetitive Reverse Voltage ($V_{RRM}$)** | 40 V | | **Continuous Forward Current ($I_{F}$)** | 350 mA | | **Forward Voltage Drop ($V_{F}$)** | ~0.37V @ 20mA | | **Reverse Recovery Time ($t_{rr}$)** | 10 ns (Typical) | | **Operating Temperature Range** | -55°C to +125°C | --- ### 2. Key Features and Functions Schottky diodes like the SD103AW differ from standard PN-junction diodes due to their metal-to-silicon junction. * **Low Forward Voltage ($V_F$):** It requires less energy to conduct electricity compared to standard diodes (which usually require 0.7V). This results in higher efficiency and less heat generation. * **Ultra-Fast Switching:** With a recovery time of 10ns, it is suitable for high-frequency rectification and signal processing. * **Guard Ring Construction:** Integrated guard ring protection for stress protection and long-term reliability. * **Small Footprint:** The SOD-123 package is ideal for compact PCB designs in mobile or handheld devices. --- ### 3. Common Applications Due to its characteristics, the SD103AW-CC2-R is commonly found in the following circuits: 1. **Low Voltage Rectification:** Converting AC to DC in low-power power supplies. 2. **Clamping Circuits:** Protecting sensitive IC inputs from overvoltage spikes. 3. **Reverse Polarity Protection:** Preventing damage if batteries or power sources are connected backward. 4. **Freewheeling Diodes:** Used in small inductive load switching (like small relays or motors). --- ### 4. Part Number Breakdown (Typical) While naming conventions vary by manufacturer (e.g., Diodes Inc, Panjit, or Vishay), the suffix generally indicates: * **SD103AW:** The base model and voltage class (40V). * **CC2:** Often refers to specific internal chip configurations or lead-frame variations. * **-R:** Typically denotes "RoHS Compliant" or "Tape and Reel" packaging for automated assembly. ---
