The **2DZ1-R** is a specific model of a **High Voltage Silicon Rectifier Diode**, typically used in industrial and television applications where high-voltage rectification is required. --- ## 1. Technical Specifications The 2DZ1-R is designed to handle high peak inverse voltages while maintaining a small form factor. Below are the typical technical parameters: | Parameter | Value | | :--- | :--- | | **Part Number** | 2DZ1-R | | **Component Type** | High Voltage Rectifier Diode | | **Peak Repetitive Reverse Voltage ($V_{RRM}$)** | 10kV - 15kV (varies by manufacturer) | | **Average Forward Current ($I_{F(AV)}$)** | 5mA - 10mA | | **Forward Voltage Drop ($V_F$)** | ~30V - 45V | | **Reverse Recovery Time ($t_{rr}$)** | Standard Recovery | | **Mounting Type** | Through-hole (Axial Lead) | --- ## 2. Key Features * **High Dielectric Strength:** The outer casing is usually epoxy-molded to prevent arcing and ensure insulation against high voltages. * **Low Leakage:** It exhibits very low reverse leakage current, which is critical for maintaining stability in high-voltage power supplies. * **Compact Design:** Despite its high voltage rating, it is relatively small, allowing for high-density PCB layouts. --- ## 3. Common Applications The 2DZ1-R is primarily found in circuits requiring the conversion of AC to DC at very high potentials: 1. **CRT Displays:** Used in the high-voltage flyback transformer circuits for older television and monitor tubes. 2. **Electrostatic Air Cleaners:** Used in the power supply to generate the static charge required to trap dust particles. 3. **X-Ray Power Supplies:** Employed in small-scale medical or industrial imaging equipment. 4. **Laser Power Supplies:** Used in the ignition and sustain circuits for gas lasers (like HeNe lasers). --- ## 4.
