PESD15VL1BA 是富芯森美(FUXINSEMI)推出的一款单路双向 ESD 保护二极管,封装为 SOD-323。器件针对瞬态浪涌和静电放电事件提供有效钳位,适用于需要对单条数据线或信号线进行双向保护的场合。工作温度范围为 -55℃ 至 +125℃,满足工业级应用的可靠性要求。
这些参数表明该器件在面对短时高能脉冲(如雷击诱发浪涌或静电放电)时能快速钳位并吸收较大能量,同时在静态工作下保持低漏电。
典型应用包括 USB 2.0/备用电源线保护、串口/控制信号防护、工业控制接口以及需要抗静电和快速瞬态抑制的板级保护点。
SOD-323 小型封装有利于节省 PCB 面积并降低封装寄生电感,但在布局时应注意:
PESD15VL1BA 为工业级温度设计(-55℃ 至 +125℃),并标注对 IEC61000-4-2 与 IEC61000-4-4 的抗扰能力。为确保长期可靠性,应遵循器件材料和焊接温度规范,并在实际环境下进行加速寿命与抗扰度测试。
结语:PESD15VL1BA 以其双向保护、高脉冲承受能力和小体积封装,适合对中等能量瞬变事件进行板级保护的应用场景。在应用前请结合电路耐压、允许钳位电压和信号速率综合评估,以获得最佳的保护效果与信号性能平衡。

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.
