PESD5V2S2UT 是友台半导体(UMW)推出的一款低电容瞬态电压抑制器(TVS/ESD 保护器件),封装为 SOT-23,主要用于对低电压信号线和接口电路的静电放电(ESD)、快速瞬变脉冲(EFT)及浪涌(Surge)进行保护。器件针对 5V 级系统优化,具有低漏电、快速响应和较高的峰值冲击吸收能力,适合移动终端、消费类电子、接口保护及通信设备等对体积和性能有较高要求的场合。
PESD5V2S2UT 作为瞬态抑制器,当线路电压在正常工作范围(≤ Vrwm = 5V)时呈高阻并保持微小漏电流;当出现瞬态过压(静电放电或浪涌)时,器件进入击穿或雪崩导通,迅速将过量能量导向地线并将电压钳制于约 16V,从而保护后级电路元件。器件的快速响应和高峰值吸收能力(300W@8/20μs,Ipp 20A)使其能有效应对常见的工业与消费环境下的冲击事件。
SOT-23 封装利于小型化设计与自动贴装,适合批量生产与 SMT 工艺。器件满足 IEC 61000-4-2/4/5 等常用抗干扰标准认证,适合需要合规性验证的工业与商业应用。
总结:PESD5V2S2UT 以其针对 5V 系统的优化参数、较高的脉冲吸收能力与小巧的 SOT-23 封装,适合对静电与瞬态浪涌有防护需求且对空间与功耗敏感的各类电子设备接口保护。若需完整的电气特性、封装图或样片/订购信息,可进一步提供数据手册或联系供应渠道。

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.
