### 1. General Overview
The AB47S-R1 is designed to convert Alternating Current (AC) to Direct Current (DC). It is commonly found in compact power supplies, chargers, and LED drivers where space is a constraint.
### 2. Technical Specifications
Typical parameters for this class of component (Standard Silicon Bridge Rectifier) include:
| Parameter | Typical Value | Unit |
| :--- | :--- | :--- |
| **Maximum Recurrent Peak Reverse Voltage** | 1000 | Volts (V) |
| **Maximum RMS Voltage** | 700 | Volts (V) |
| **Maximum DC Blocking Voltage** | 1000 | Volts (V) |
| **Maximum Average Forward Rectified Current** | 1.0 - 2.0 | Amperes (A) |
| **Peak Forward Surge Current** | 30 - 50 | Amperes (A) |
| **Operating Temperature Range** | -55 to +150 | °C |
### 3. Key Features
* **Surface Mount Design (SMD):** The "S" in the suffix often denotes a surface-mount package (like ABS or DFS), ideal for automated PCB assembly.
* **Glass Passivated Junction:** This technology ensures high reliability and stability against moisture and environmental contaminants.
* **Low Forward Voltage Drop:** This minimizes power loss and heat generation during operation.
* **High Surge Capacity:** Capable of handling brief spikes in current without failing.
### 4. Pin Configuration
Most components in this series feature a 4-pin layout:
1. **AC Input (~):** Connects to the incoming alternating current.
2. **AC Input (~):** Second terminal for the AC source.
3. **Positive Output (+):** Rectified DC positive terminal.
4. **Negative Output (-):** Rectified DC negative (ground) terminal.
