ESD56281N05-2/TR 是 WILLSEMI(韦尔)推出的一款单向 TVS(瞬态抑制)二极管,封装为 DFN1006-2L(小型双引脚贴片)。器件针对静电放电(ESD)与浪涌抑制进行了优化,满足 IEC 61000-4-2(ESD)和 IEC 61000-4-5(浪涌)相关防护等级,适用于工业及消费类电子产品中对端口及电源线的瞬态保护需求。
以上参数表明该器件在 5.5 V 级别的电源及信号线上提供可靠的单向浪涌/ESD 保护,低漏电和适中结电容使其在多数控制与接口线路中兼顾保护与信号完整性。
需要注意:Cj=160 pF 在某些极高速接口(例如要求极低电容的高速差分信号链)可能影响信号完整性,应用前应根据带宽需求评估。
ESD56281N05-2/TR 为一款针对 5.xV 级系统设计的单向 TVS 二极管,具备 40 A(8/20 μs)峰值浪涌承受能力、低漏电和符合 IEC ESD/浪涌标准的防护性能。其 DFN1006-2L 小封装适合紧凑型 PCB 布局,是对电源线与常见接口进行瞬态防护的实用选择。在高速信号应用中,请结合 160 pF 的结电容特性进行详细评估与测试。若需进一步的原理图接法、参考 PCB 布局或老化/测试数据,可根据具体应用场景提供更详细的设计支持。

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.
