RCLAMP0524S.TCT是SEMTECH(赛米控) 推出的一款四路集成式ESD保护TVS二极管,专为低电压系统的静电放电(ESD)防护设计。该器件采用SOT23-6小型封装,体积紧凑,适配消费电子、可穿戴设备、物联网(IoT)模块等对空间要求严格的场景,可同时为4个独立信号通道提供可靠防护。
器件参数围绕“低电压ESD防护”核心需求设计,关键参数及意义如下:
指正常工作状态下,器件反向偏置可承受的最大直流电压(不得超过5V)。此参数匹配3.3V/5V供电的MCU、传感器等低电压系统,确保信号传输时器件不导通,不干扰电路功能。
当反向电压超过5V并达到6V时,器件从截止态转为导通态,触发ESD保护。击穿电压略高于Vrwm,明确区分“正常工作”与“防护触发”两种状态。
指ESD脉冲触发后,器件能将峰值电压钳位到的最高值(典型测试条件下)。26V远低于敏感器件的损坏阈值(通常>30V),可有效抑制静电冲击,避免芯片击穿、数据丢失。
集成4个独立TVS单元,可同时防护4个信号通道(如USB数据线、I2C总线、音频接口等),减少PCB器件数量,简化电路设计。
该器件采用SOT23-6封装,具备以下优势:
针对低电压、多通道防护需求,典型应用包括:
该器件以“小体积、多通道、低电压防护”为核心,是低功耗电子设备ESD防护的高性价比选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
