ESD56201D04-2/TR 是 WILLSEMI(韦尔)推出的单路、单向瞬态电压抑制器(TVS),用于对静电放电(ESD)和浪涌(Surge)瞬态进行硬件级保护。器件采用小型 DFN1610-2L 封装,针对汽车电子、消费电子和工业控制中对电源或信号线的过压防护需求设计。其符合 IEC 61000-4-2(ESD)和 IEC 61000-4-5(浪涌)等标准,适合在受干扰环境中提供可靠保护。
器件设计满足 IEC 61000-4-2(静电放电)和 IEC 61000-4-5(浪涌)相关要求,适合通过整机的抗扰度测试。器件工作温度范围覆盖工业级(-40 ℃ 至 +85 ℃),适用于大多数工业与消费级应用。实际项目中应做板级和系统级 EMC 验证,确认在真实扰动下系统能稳定运行。
DFN1610-2L 小型扁平封装利于表面贴装。焊盘设计应参考厂商推荐焊盘图,良好的焊接与热解散布对可靠性和脉冲能量承受能力有直接影响。封装体积小便于在空间受限的终端设备中部署。
ESD56201D04-2/TR 是面向 5 V 及以下电源轨和低速接口的高能量单向 TVS,适合需要高脉冲吸收能力且对漏电流敏感的应用。在使用时重点关注结电容对信号完整性的影响、Vrwm 与系统电压的匹配以及 PCB 接地与热散布设计,能够获得最佳的抗浪涌与抗静电性能。如需在高速数据线或更高工作电压场景下保护,请考虑选型更合适的 TVS 或配合其他滤波器件共同设计保护方案。

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.
