RL0402E005M300K 产品概述

RL0402E005M300K 是 RUILON(瑞隆源)推出的一款面向信号线的单路低容抗静电元件,采用 0402 超小贴片封装,专为 PCB 上的敏感信号口提供瞬态静电放电(ESD)保护而设计。器件在保持极小安装面积的同时兼顾低结电容和快速钳位性能,适用于对尺寸与信号完整性要求较高的便携设备与工业接口。

一、产品简介

本器件为单路 ESD 防护二极管类产品,工作稳压(反向截止)电压 Vrwm 为 5V,典型用于 5V 以内电源或数据线的防护。器件反向静态电流(Ir)仅 1 μA,结电容(Cj)约 3 pF,能在保证低泄漏的前提下对高速或高带宽信号线干扰影响最小化。器件工作温度范围为 -55 ℃ 至 +85 ℃,适应多数消费与工业环境。

二、主要性能参数

  • 品牌:RUILON(瑞隆源)
  • 型号:RL0402E005M300K
  • 类型:ESD 静电保护元件(单路)
  • 反向截止电压(Vrwm):5 V
  • 钳位电压(Vclamp):25 V(典型/最大值,响应于冲击事件)
  • 击穿电压(Vbr):50 V
  • 反向电流(Ir):1 μA(在 Vrwm 下)
  • 结电容(Cj):3 pF(典型)
  • 封装:0402 SMD
  • 工作温度:-55 ℃ ~ +85 ℃

三、核心特性

  • 小尺寸:0402 封装,有利于高密度 PCB 布局与轻薄产品设计。
  • 低结电容:3 pF 的典型值可以最大程度降低对高速信号(如高速数据总线、串口等)的影响,保持信号完整性。
  • 低泄漏电流:1 μA 反向电流可确保在待机或低功耗电路中不产生明显漏电。
  • 高钳位能力:在瞬态事件时钳位电压为 25 V,能够将高能脉冲电压限制在相对安全范围内,保护后端器件。
  • 宽温度范围:-55 ℃ 至 +85 ℃ 满足大多数工业与消费类环境需求。

四、典型应用场景

  • USB、UART、I2C、SPI 等低电压数据线与接口的 ESD 保护;
  • 手机、平板、可穿戴设备等对 PCB 空间敏感的消费电子产品;
  • 摄像头模块、触摸屏接口及传感器信号保护;
  • 工业控制设备、测量仪表中对单路信号线的局部防护。

五、封装与焊接建议

  • 封装为 0402(1.0 mm × 0.5 mm 量级),建议在贴装工艺中采用常规回流焊温度曲线,遵循无铅或含铅工艺规范。
  • 布局建议:将保护器件尽量靠近受保护的接口或连接器放置,减少走线长度以降低感抗与寄生电容对防护效果的削弱。
  • 接地建议:若为单端保护,确保靠近器件的地平面良好、回流路径短且阻抗低,以提高放电能力与可靠性。

六、可靠性与注意事项

  • 本器件设计用于抑制瞬态过压与静电放电,不作为连续限压或电流导通器件使用。
  • 在选型时确认最大脉冲能量与系统可能遭遇的冲击类型,必要时采用多级防护(如串联阻尼、共模扼流圈或更大能量的 TVS)以增强系统可靠性。
  • 存储与回流过程中应避免超过封装及材料耐温性限制,遵循供应商提供的焊接温度曲线与储存条件。

七、采购与型号信息

  • 型号:RL0402E005M300K,品牌:RUILON(瑞隆源)。
  • 封装:0402,适合 SMT 自动贴装。
  • 常见包装形式为卷带(Tape & Reel),便于大批量 SMT 生产线使用。
  • 在采购或设计阶段,请参考瑞隆源提供的完整器件规格书(datasheet)以获取更详细的电气特性曲线、典型应用电路与可靠性测试数据。

总结:RL0402E005M300K 以其超小封装、低结电容与低漏电特性,适合对 PCB 空间与信号完整性有严格要求的应用场景,是面向 5V 级别信号口的经济且高效的 ESD 防护选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
