ESD5451NL-2/TR 是 WILLSEMI(韦尔)推出的一款单路、双向瞬态抑制二极管(TVS),专为 5V 级电源和信号线的静电放电(ESD)与浪涌(Surge)保护设计。主要参数:工作反向电压 VRWM = 5V;最小击穿电压 VBR(min) = 5.2V;钳位电压 VC = 11V(Ipp=4A,8/20μs);峰值脉冲电流 Ipp = 4A(8/20μs);峰值功率 Ppk = 44W;结电容 Cj ≈ 11pF;反向漏电流 Ir ≤ 500nA;封装为 DFN1006-2L,单通道双向结构,适配贴片自动化生产(TR=带卷包装)。
DFN1006-2L 为超小表贴封装,推荐布局要点:
总结:ESD5451NL-2/TR 在小尺寸封装下提供 5V 级别的可靠双向瞬态抑制,适用于需要节省 PCB 空间且对钳位效率和合规性有要求的消费电子与工业应用。在高带宽场合请选择更低电容替代品;在 5V 电源与一般 I/O 保护方面,本器件为性价比较高的选择。

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.
