The **AS4V-Z15A-R** is a specific part number typically associated with **Solid State Relays (SSR)** or high-performance industrial switching components, often manufactured by brands like **Panasonic** or **Alps Alpine** (though specific branding can vary by distributor). Below is a detailed breakdown of the electronic characteristics and technical specifications typical for this component series. --- ### 1. General Specifications The AS4V series is designed for precision switching in industrial automation. It is a high-sensitivity, high-reliability component. | Feature | Description | | :--- | :--- | | **Component Type** | Solid State Relay (SSR) / Control Relay | | **Mounting Type** | Surface Mount (SMD) or PCB Through-hole (depending on suffix) | | **Contact Form** | Typically 1 Form A (SPST-NO) | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | ### 2. Electrical Characteristics These parts are engineered to handle specific voltage and current loads with minimal electrical noise. * **Load Voltage:** Usually rated up to **60V - 400V** (Model dependent). * **Load Current:** Typically in the range of **0.1A to 2.0A**. * **Input-to-Output Isolation:** High dielectric strength (often >1500V AC). * **On-Resistance:** Low internal resistance to prevent heat buildup during operation. ### 3. Pinout and Internal Logic The internal structure usually consists of an LED on the input side and a MOSFET/Triac on the output side. ```mermaid graph LR A[Input +] --> B(Internal LED) B --> C[Input -] D[Output 1] --- E(Photo-MOS / Switching) E --- F[Output 2] B -. Optical Link .- E ``` ### 4. Part Number Breakdown The nomenclature for this series generally follows this logic: 1. **AS4V**: Series designation (Vertical/High-density SSR). 2. **Z**: Termination style (e.g., Z-bend for surface mounting). 3. **15A**: Capacity/Voltage rating code. 4. **R**: RoHS Compliance and/or Taping/Reel packaging. --- ### 5. Common Applications * **Telecommunications:** Signal switching and line control. * **Medical Equipment:** Isolated monitoring circuits. * **Industrial Controls:** Programmable Logic Controllers (PLCs) and I/O modules. * **Measurement Devices:** High-speed testing equipment requiring long life cycles (unlike mechanical relays). ---
