The **VBO13-16AO2** is a high-power **Single Phase Rectifier Bridge** manufactured by IXYS (now part of Littelfuse). It is designed to convert alternating current (AC) into direct current (DC) in industrial applications. --- ### ## Technical Specifications Below are the primary electrical characteristics of the component: | Parameter | Value | Description | | :--- | :--- | :--- | | **$V_{RRM}$** | 1600 V | Peak Repetitive Reverse Voltage | | **$I_{dAV}$** | 15 A | Average Forward Current (at $T_C = 110^\circ C$) | | **$I_{FSM}$** | 200 A | Surge Forward Current (10ms sine wave) | | **$V_F$** | 1.1 V | Forward Voltage Drop (per diode) | | **Package** | PWS-A | Through-hole power module | | **Configuration** | Bridge | 4 Diodes in a single phase bridge | --- ### ## Key Electronic Features #### 1. Planar Passivated Chips The internal diodes use planar passivation technology. This ensures low leakage current and high reliability under thermal stress, protecting the junction from contaminants. #### 2. Isolation and Heat Transfer * **Direct Copper Bonding (DCB):** The internal ceramic plate provides excellent electrical isolation (up to 2500V RMS) while maintaining low thermal resistance. * **Heat Dissipation:** The metal base plate allows the component to be bolted directly to a heatsink. #### 3. High Voltage Rating The **16** in the part number indicates a **1600V** rating. This provides a significant safety margin for standard 230V or 480V AC power lines, protecting against voltage spikes and transients. --- ### ## Internal Circuit Diagram The VBO13-16AO2 contains four diodes arranged in a standard bridge configuration: ```text AC (~) AC (~) | | +----|-----+ +----|-----+ | | | | | | [D1] [D2] [D3] [D4] (Diodes) | | | | | | +----|-----+ +----|-----+ | | DC (+) DC (-) ``` --- ### ## Common Applications * **Power Supplies:** Input rectification for Switch Mode Power Supplies (SMPS). * **DC Motor Drives:** Converting AC mains to DC for motor controllers. * **Battery Chargers:** High-voltage industrial charging systems. * **Inverters:** Input stage for frequency converters and UPS systems.
