The **SK560SC** is a high-performance Schottky Barrier Rectifier diode commonly used for power management and rectification. Below is a detailed breakdown of its electronic specifications and characteristics. --- ## 1. Key Technical Specifications The SK560SC is designed for surface-mount applications (SMD) and is characterized by low power loss and high efficiency. | Parameter | Symbol | Typical Value | | :--- | :--- | :--- | | **Maximum Repetitive Peak Reverse Voltage** | $V_{RRM}$ | 60 V | | **Maximum Average Forward Rectified Current** | $I_{F(AV)}$ | 5.0 A | | **Peak Forward Surge Current** (8.3ms half sine) | $I_{FSM}$ | 120 A | | **Maximum Forward Voltage** (at $I_F = 5.0A$) | $V_F$ | 0.70 V | | **Maximum Reverse Current** (at $V_{DC}$) | $I_R$ | 0.5 mA | | **Operating Junction Temperature** | $T_J$ | -55 to +150 °C | | **Package Type** | Case | SMC (DO-214AB) | --- ## 2. Core Features * **Schottky Barrier Chip:** Uses a metal-to-silicon junction to achieve fast switching speeds and low forward voltage drops. * **Guardring Protection:** Usually includes an internal guardring for transient protection (over-voltage stress). * **Low Power Loss:** High efficiency due to the low $V_F$, which reduces heat dissipation during operation. * **Surface Mount Technology (SMT):** Optimized for automated assembly on PCBs. --- ## 3. Typical Applications The SK560SC is primarily used in circuits where high frequency and low power loss are critical: 1. **Switching Mode Power Supplies (SMPS):** Used for output rectification. 2. **DC-DC Converters:** Acts as a freewheeling diode or polarity protection. 3. **Battery Chargers:** Prevents reverse current flow from the battery to the charger. 4. **Inverters:** High-speed switching applications. --- ## 4. Pin Configuration and Package The device comes in an **SMC (DO-214AB)** molded plastic package. * **Polarity:** The color band denotes the **Cathode** end. * **Mounting Position:** Any. * **Terminals:** Solderable per MIL-STD-750. ```text SMC Package Layout _______________________ | | | | Cathode | Anode | | [-] | [+] | <-- (Current flows + to -) |__________|____________| (Band) ```
