The **CD214A-R11600** is a Glass Passivated Rectifier Diode manufactured by Bourns. It is primarily designed for power supplies, battery chargers, and general-purpose rectification applications where space-saving and surface-mount technology (SMT) are required. --- ### ## Technical Specifications Below are the primary electrical and physical characteristics of the CD214A-R11600: | Parameter | Value / Description | | :--- | :--- | | **Component Type** | General Purpose Rectifier Diode | | **Package / Case** | DO-214AC (SMA) | | **Peak Repetitive Reverse Voltage ($V_{RRM}$)** | 600 V | | **Maximum Average Forward Current ($I_{F(AV)}$)** | 1.0 A | | **Peak Forward Surge Current ($I_{FSM}$)** | 30 A (8.3 ms half sine-wave) | | **Maximum Forward Voltage ($V_F$)** | 1.1 V @ 1.0 A | | **Maximum Reverse Current ($I_R$)** | 5.0 $\mu$A @ 600 V | | **Operating Temperature Range** | -55°C to +150°C | --- ### ### Key Features 1. **Glass Passivated Chip:** The internal silicon wafer is coated with a glass layer, which improves stability, lowers leakage current, and enhances reliability under high temperatures. 2. **Low Profile Design:** The SMA (DO-214AC) package is ideal for automated assembly and helps reduce the overall height of the PCB. 3. **High Surge Capability:** Despite its small size, it can handle a 30A surge, making it robust against temporary power spikes. 4. **Compliance:** Typically RoHS compliant and halogen-free, meeting modern environmental standards. --- ### ### Application Use Cases This diode is versatile and commonly found in: * **AC-to-DC Rectification:** Standard bridge rectifiers for small power adapters. * **Freewheeling Diodes:** Used to protect circuits from inductive voltage spikes (e.g., in relays or small motors). * **Reverse Polarity Protection:** Preventing damage to a circuit if the battery or DC input is connected backward. * **Switching Power Supplies (SMPS):** Secondary-side rectification. --- ### ### Pinout and Marking The component is polarized. The **Cathode** is indicated by a colored band on the body of the SMA package. ```text SMA Package (Top View) ___________________________ | | | | [Band] | Marking Code | | (Cath) | R11600 | |__________|________________| ```
