ESD56161D04-3/TR 是 WILLSEMI(韦尔)推出的一款单向瞬态电压抑制(TVS)二极管,封装为 DFN2x2-3L。器件专为对抗静电放电(ESD)和雷击浪涌(Surge)干扰而设计,适用于需要稳压保护的低电压线路,尤其是对 5V 体系的浪涌与静电防护场合。
该器件适合用于 USB、充电口、电源轨及需要对大冲击能量进行抑制的接口保护场景,尤其是对抗雷击浪涌与强烈静电放电。由于结电容较高(4200 pF),不推荐直接用于高频高速差分信号(如高速 USB 3.0、差分高速数据总线)上,以免影响信号完整性。更适合用于电源线、低速控制信号或作为总线上级保护器件。
DFN2x2-3L 小型封装利于紧凑 PCB 布局。推荐实践:
总结:ESD56161D04-3/TR 提供高能量吸收能力与合规的 ESD/Surge 防护,体积小巧,适用于 5V 类电源与低速信号的抗干扰保护。在布板与选型环节需重点考虑其较高的结电容与钳位特性,以确保系统信号完整性与下游器件安全。

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.
