PESD5V2S2UT(品牌:DOWO/东沃)是一款双路、单向的瞬态电压抑制(ESD)器件,封装为SOT-23,专为对接口信号和电源线进行静电放电(ESD)、电快速瞬变(EFT)和浪涌(Surge)保护而设计。器件在5V工作电压下提供有效的浪涌吸收能力,满足常见工业与消费电子接口的电气稳健性要求。
主要参数一览:
注意:由于结电容约为 190pF,器件会对高速差分信号(如 USB3.0、HDMI、高速以太网等)造成明显的链路衰减或失真,因此不推荐用于这些高速差分传输线的直接保护。更适合用于低速信号或电源线防护。
(具体引脚定义请参照厂家数据手册以确认引脚顺序与接地要求)
结语:PESD5V2S2UT 是一款面向 5V 及以下系统、提供双路单向保护的成本效益型器件,适合多数需要 IEC 级别抗扰度且对高速信号吞吐要求不高的应用场合。在最终设计中,请结合器件完整数据手册和实际系统需求(特别是结电容与钳位特性)进行验证与布局优化。

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.
