## Overview of CD214B-R3600 The **CD214B-R3600** is a Glass Passivated Rectifier Diode manufactured by Bourns. It is designed for power rectification and is housed in a surface-mount SMB (DO-214AA) package. This specific part is known for its high voltage capability and reliability in compact electronic circuits. --- ### Technical Specifications | Parameter | Specification | | :--- | :--- | | **Component Type** | Rectifier Diode | | **Maximum Repetitive Peak Reverse Voltage ($V_{RRM}$)** | 600 V | | **Maximum Average Forward Current ($I_{F(AV)}$)** | 3.0 A | | **Forward Voltage Drop ($V_F$) @ 3A** | 1.15 V (Maximum) | | **Maximum Peak Forward Surge Current ($I_{FSM}$)** | 100 A | | **Operating Junction Temperature** | -55°C to +150°C | | **Package Type** | SMB / DO-214AA (Surface Mount) | --- ### Key Features and Construction 1. **Glass Passivated Chip Junction:** The internal silicon wafer is protected by a layer of glass. This improves stability against environmental factors and ensures low leakage current under high temperatures. 2. **High Current Capability:** Despite its small footprint, it can handle a continuous average forward current of **3 Amperes**, making it suitable for power supply outputs. 3. **Standard Recovery:** This is a "General Purpose" or "Standard Recovery" diode. It is optimized for low-frequency applications (like 50/60Hz AC rectification) rather than high-speed switching. 4. **RoHS Compliant:** The part is lead-free and meets modern environmental safety standards for electronic manufacturing. --- ### Common Applications * **AC-to-DC Rectification:** Used in bridge rectifiers or half-wave rectifiers for power adapters. * **Reverse Polarity Protection:** Prevents damage to a circuit if the DC power supply is connected backward. * **Freewheeling Diode:** Used in inductive loads (relays, motors) to suppress voltage spikes. * **Switching Power Supplies:** Acts as a secondary side rectifier in lower frequency power converters. --- ### PCB Design Considerations To use this part effectively in a design, consider the following code snippet representation of its footprint requirements (Generic SMB): ```markdown Package: DO-214AA (SMB) - Length: 4.06 mm - 4.57 mm - Width: 3.30 mm - 3.94 mm - Height: 2.13 mm - 2.44 mm - Polarity: Color band denotes Cathode (-) ``` ---
