The part number **10PV-2D6-R** typically refers to a high-voltage, high-reliability **Diode** or **Rectifier**, often used in specialized power electronics, aerospace, or industrial high-voltage power supplies. --- ### 1. General Specifications While specific manufacturers (such as Dean Technology or specialized HV suppliers) may vary slightly, this series generally follows these parameters: | Parameter | Typical Value | Description | | :--- | :--- | :--- | | **Component Type** | High Voltage Rectifier | Standard recovery or fast recovery diode | | **Max Peak Inverse Voltage (PIV)** | 10,000V (10kV) | The maximum voltage the diode can withstand in reverse | | **Average Forward Current ($I_f$)** | ~200mA to 500mA | Varies by mounting/cooling environment | | **Package Style** | Axial Lead / Molded | Cylindrical epoxy body with wire leads | | **RoHS Status** | -R Suffix | Typically indicates "RoHS Compliant" | --- ### 2. Breakdown of Part Number Syntax Most high-voltage components use a functional coding system: * **10**: Represents the voltage rating. In this context, it usually signifies **10kV**. * **PV**: Often stands for "Power Voltage" or is a specific manufacturer series designation for high-voltage silicon rectifiers. * **2D6**: This internal code usually specifies the chip geometry, current rating (e.g., 200mA range), and recovery speed. * **-R**: Indicates compliance with environmental standards (RoHS - Restriction of Hazardous Substances). --- ### 3. Key Technical Characteristics #### A. Electrical Performance * **Low Leakage:** These diodes are designed to have extremely low reverse leakage current to prevent thermal runaway at high voltages. * **Series Stacking:** Internally, these parts often consist of multiple diode "dice" stacked in series to achieve the 10kV rating. * **Voltage Drop:** Because of the internal series stack, the forward voltage drop ($V_f$) is much higher than a standard diode (typically 10V to 15V). #### B. Physical Construction * **Encapsulation:** High-dielectric epoxy resin to prevent arcing across the surface of the component. * **Lead Finish:** Usually tinned copper leads for easy soldering onto PCBs or high-voltage terminal blocks. --- ### 4. Common Applications Due to its high voltage rating, the **10PV-2D6-R** is found in: * **X-Ray Machines:** Powering the vacuum tube anodes. * **Laser Power Supplies:** High-voltage ignition circuits. * **Electrostatic Precipitators:** Used in industrial air filtration. * **CRT Monitors/Displays:** Legacy high-voltage flyback circuits. --- ### 5. Circuit Symbol and Implementation In a schematic, it is represented as a standard diode, but designers must account for the high voltage clearance (creepage and clearance distances). ```markdown (Anode) ----|>|---- (Cathode/Band) 10kV Diode ```
