### BAT54AWL-AL3-R Technical Overview The **BAT54AWL-AL3-R** is a specific variant of the widely used BAT54 series. It is a **Schottky Barrier Diode** featuring a dual-configuration (Common Anode) housed in a small surface-mount package. --- ### 1. Key Technical Specifications Below are the primary electrical characteristics for this component: | Parameter | Symbol | Value | Unit | | :--- | :--- | :--- | :--- | | **Continuous Reverse Voltage** | $V_R$ | 30 | V | | **Forward Continuous Current** | $I_F$ | 200 | mA | | **Forward Voltage (Max @ 1mA)** | $V_F$ | 0.32 | V | | **Forward Voltage (Max @ 100mA)** | $V_F$ | 1.0 | V | | **Reverse Recovery Time** | $t_{rr}$ | 5.0 | ns | | **Total Capacitance** | $C_T$ | 10 | pF | --- ### 2. Internal Configuration & Package The "AWL" suffix indicates the specific pinout and package style: * **Configuration:** Dual Diode, **Common Anode**. This means the two anodes are connected to a single pin, while the two cathodes are separate. * **Package Type:** Typically **SOT-323** (or SC-70). This is a miniature version of the SOT-23, ideal for high-density circuit boards. * **Lead-Free:** The "-R" usually denotes RoHS compliance and Tape & Reel packaging for automated assembly. --- ### 3. Distinctive Features * **Low Forward Voltage:** Because it is a Schottky diode, it has a much lower $V_F$ than standard silicon diodes (0.3V vs 0.7V). * **Ultra-Fast Switching:** With a recovery time of 5ns, it is suitable for high-speed signal processing. * **Guard Ring Construction:** Includes a guard ring for transient protection and to minimize leakage current. --- ### 4. Common Applications Due to its small size and fast response, it is used in: 1. **Signal Clamping:** Protecting sensitive IC inputs from overvoltage. 2. **Reverse Polarity Protection:** For low-current battery-powered devices. 3. **High-Speed Switching:** Used in RF and communication circuits. 4. **Voltage Doublers:** Often used in small power management sub-circuits. ---
