The **CD214A-R150** is a fast-recovery rectifier diode manufactured by Bourns. It is designed for high-efficiency power rectification in compact electronic circuits. ### 1. General Specifications Below are the primary electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Component Type** | Rectifier Diode (Fast Recovery) | | **Maximum Repetitive Peak Reverse Voltage ($V_{RRM}$)** | 50 V | | **Maximum Average Forward Current ($I_{F(AV)}$)** | 1.0 A | | **Maximum Peak Forward Surge Current ($I_{FSM}$)** | 30 A | | **Maximum Forward Voltage Drop ($V_F$)** | 1.25 V @ 1A | | **Reverse Recovery Time ($t_{rr}$)** | 35 ns (Nanoseconds) | | **Package Type** | SMA (DO-214AC) | --- ### 2. Key Features * **Fast Recovery Time:** The 35ns recovery time makes it suitable for high-frequency switching applications where standard diodes would be too slow and cause power loss. * **Surface Mount Design:** The CD214A package is an industry-standard **SMA (DO-214AC)**, which is low-profile and ideal for automated pick-and-place assembly. * **High Reliability:** It features a glass-passivated chip junction to ensure stability and low leakage current. * **RoHS Compliant:** The part is lead-free and meets modern environmental standards. --- ### 3. Application Use Cases This diode is typically found in circuits where efficiency and speed are critical: 1. **DC-DC Converters:** Used as a freewheeling diode to handle inductive spikes. 2. **Switching Power Supplies (SMPS):** Rectifying high-frequency AC signals into DC. 3. **Inverters:** Managing polarity and preventing backflow in power conversion. 4. **Reverse Polarity Protection:** Protecting sensitive components from incorrectly connected power sources in battery-powered devices. --- ### 4. Package Dimensions (SMA) The physical footprint is small, allowing for high-density PCB layouts: | Dimension | Typical Measurement | | :--- | :--- | | **Length** | ~5.0 mm (including leads) | | **Width** | ~2.6 mm | | **Height** | ~2.2 mm |
