## Electronic Specifications and Details for ES2DBF The **ES2DBF** is a Surface Mount (SMD) **Super Fast Recovery Rectifier**. It is widely used in power management circuits due to its high efficiency and high-speed switching capabilities. --- ### 1. General Overview The ES2DBF belongs to the **ES2x series**. It is designed for applications where low power loss and high efficiency are critical. The "D" typically refers to the voltage rating, and "BF" refers to the specific package type (SMBF). ### 2. Key Technical Specifications Below are the primary electrical characteristics for the ES2DBF: | Parameter | Symbol | Value | Unit | | :--- | :--- | :--- | :--- | | **Maximum Repetitive Peak Reverse Voltage** | $V_{RRM}$ | 200 | V | | **Maximum RMS Voltage** | $V_{RMS}$ | 140 | V | | **Maximum Average Forward Rectified Current** | $I_{F(AV)}$ | 2.0 | A | | **Peak Forward Surge Current (8.3ms half sine)** | $I_{FSM}$ | 50 | A | | **Maximum Forward Voltage (at 2.0A)** | $V_{F}$ | 0.95 | V | | **Maximum Reverse Recovery Time** | $t_{rr}$ | 35 | ns | | **Operating Junction Temperature** | $T_J$ | -55 to +150 | °C | --- ### 3. Key Features * **Super Fast Switching:** With a $t_{rr}$ of only 35 nanoseconds, it minimizes switching losses. * **Low Profile Package:** The **SMBF** package is thinner than the standard SMB (DO-214AA), making it ideal for slim electronic devices. * **High Surge Capacity:** Capable of handling up to 50A of surge current, providing robustness against circuit start-up spikes. * **Glass Passivated Die Construction:** Ensures high reliability and low leakage current. --- ### 4. Physical Dimensions & Footprint The ES2DBF uses the **SMBF package**, which is a flat lead plastic package. ```text SMBF Package Outline (Typical): - Length: 4.2 - 4.4 mm - Width: 3.5 - 3.7 mm - Height: 1.1 - 1.3 mm (Low profile) ``` --- ### 5. Common Applications 1. **SMPS (Switching Mode Power Supplies):** Used for output rectification. 2. **Inverters:** Used in DC-DC converters for high-frequency rectification. 3. **Freewheeling Diodes:** Protects circuits from inductive voltage spikes in motors or relay drivers. 4. **Polarity Protection:** Prevents damage from reverse battery connection in automotive or portable electronics.
