RLSD52A051V 产品概述
一、产品简介
RLSD52A051V 是 RUILON（瑞隆源）推出的一款单向瞬态电压抑制二极管（TVS），专为 5V 工作电压的电源和信号线提供过压、浪涌和静电放电（ESD）保护。器件采用超小型 SOD-523 封装，适合空间受限的便携式与消费类电子设计，校验通过，可靠性高，便于自动贴装生产。
二、主要特性
- 极性：单向（单路保护）
- 反向截止电压 Vrwm：5V（适配标准 5V 总线）
- 钳位电压 Vc：9V（在峰值电流下有效限制电压）
- 峰值脉冲电流 Ipp：5A（单次浪涌抑制能力）
- 工作温度：-55℃ ~ +150℃
- 防护等级：符合 IEC 61000-4-2（静电放电抗扰度）
- 封装：SOD-523，适合高密度 PCB 布局
三、典型应用
- USB、UART、I2C 等 5V 信号线与接口保护
- 工业控制、通信模块、物联网终端的电源输入保护
- 消费电子、移动设备、可穿戴设备的局部浪涌和 ESD 抑制
- PCB 上靠近连接器或外露引脚的浪涌保护点
四、设计与使用建议
- 靠近需保护的接口或器件引脚布放，尽量缩短与被保护节点之间的走线，降低电感和串联阻抗。
- 单向 TVS 的阳极通常接地，阴极接被保护的电源/信号线，请按器件极性正确放置。
- 在高能量浪涌场合，可与熔断器或限流电阻配合使用，以提升系统整体耐受能力并避免器件过热。
- 考虑焊接工艺与回流温度，SOD-523 适用于常规 SMT 回流工艺；存储和工作环境应避免超出推荐温度范围。
五、封装与可靠性
SOD-523 超小型封装占位小、寄生电感低，适合高密度布线。器件工作温度覆盖 -55℃~+150℃，并通过 IEC61000-4-2 静电放电测试，适用于多种严苛应用场景。RUILON 品牌提供批量供货与质量追溯，适合工业与消费级批量生产。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
