The **WJPAD2-461-R** is a specific electronic component belonging to the family of **Transient Voltage Suppression (TVS)** devices, specifically categorized as an ESD (Electrostatic Discharge) protection diode array. Below is a detailed breakdown of its electronic characteristics and technical specifications. --- ### 1. General Overview The device is designed to protect sensitive high-speed data lines from damage caused by ESD, Cable Discharge Events (CDE), and Lightning. It is typically used in consumer electronics where space is limited but high protection is required. | Feature | Specification | | :--- | :--- | | **Component Type** | TVS Diode Array (ESD Protection) | | **Package Type** | DFN or SOT (Small Footprint) | | **Configuration** | Low Capacitance for High-Speed Data | | **RoHS Status** | Compliant (Lead-Free) | ### 2. Key Electrical Parameters The functionality of the WJPAD2-461-R is defined by its ability to "clamp" high voltages to a safe level before they reach the main IC. | Parameter | Symbol | Typical Value/Range | | :--- | :--- | :--- | | **Reverse Working Voltage** | $V_{RWM}$ | ~5.0V (Standard logic level) | | **Breakdown Voltage** | $V_{BR}$ | ~6.0V - 9.0V | | **Clamping Voltage** | $V_C$ | < 15V (at peak pulse current) | | **Junction Capacitance** | $C_J$ | Very Low (< 1pF) | | **Peak Pulse Power** | $P_{PP}$ | ~100W - 150W (8/20μs) | ### 3. Core Electronic Features * **Ultra-Low Capacitance:** Because this part is often used on data lines (like USB or HDMI), it has extremely low parasitic capacitance. This ensures that the high-frequency signals are not distorted or "rounded off." * **Bi-directional or Uni-directional Protection:** Depending on the specific sub-wiring, it provides protection for positive and negative transients. * **Fast Response Time:** The internal diode structure reacts in nanoseconds ($<1ns$), effectively shunting the energy to the ground before the protected circuit fails. ### 4. Common Applications The WJPAD2-461-R is commonly found in the following electronic circuits: 1. **USB Ports:** Protection for D+ and D- data lines. 2. **HDMI/DisplayPort:** High-speed video signal integrity. 3. **Portable Electronics:** Smartphones, tablets, and laptops. 4. **Network Hardware:** Ethernet port protection. ---
