PESD5V0U1BA 是 UMW(友台半导体)推出的一款单路双向瞬态电压抑制器(TVS),采用 SOD-323 小型封装,专为对敏感信号线和接口进行 ESD/浪涌保护而设计。器件在工作电压 5V 条件下具有极低的泄漏电流和适合高速信号的结电容,适用于移动设备、消费电子、工业接口等空间受限且对信号完整性有要求的应用场景。
PESD5V0U1BA 的双向结构可对正向与反向的瞬态脉冲进行对称钳位,适合信号线可能出现反向瞬态的场景(例如数据差分线、接口保护)。低至 5 nA 的反向漏电流保证在待机和低功耗模式下不会增加明显静态功耗;2.9 pF 的结电容有利于保持高速接口的信号完整性,减少串扰和信号失真。小巧的 SOD-323 封装便于贴片化、节省 PCB 面积并兼容常见回流焊工艺。
器件符合 IEC 61000-4-2 ESD 抗扰度要求,可有效吸收人体模型和机器模型的静电放电冲击,提升产品在实际应用中的抗干扰能力。在选型时仍建议基于目标系统的电磁兼容(EMC)测试结果来确认保护方案的充分性。
总结:PESD5V0U1BA 以其双向保护、低漏电、低结电容和紧凑封装,为 5V 类接口和高速信号提供了平衡的 ESD 保护解决方案,适合对空间和信号完整性都有较高要求的电子产品设计。若需完整电气特性曲线、钳位电压或 PCB 推荐封装图,请参考 UMW 官方数据手册或联系供应商获取详细资料。

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.
