PESD5V0V1BB 是东沃(DOWO)出品的一款单路双向静电放电(ESD)与浪涌保护二极管,封装为超小型 SOD-523。器件为双向结构,适用于需要双极性过压保护的信号/电源线,工作温度范围宽(-55℃~+125℃),并满足 IEC 61000-4-2(ESD)与 IEC 61000-4-5(浪涌)规范,适合消费电子、通信接口及各种易受瞬态干扰的应用场景。
该器件在标称工作电压 5 V 下提供稳态保护,击穿点约 5.5 V,当遭受 ESD/浪涌脉冲(例如峰值电流 8 A)时,器件将钳位到约 15 V 以保护后端电路。静态漏电小(Ir≈500 nA),但结电容约 15 pF,设计高速差分信号通道时需评估对信号的影响。
(注:如用于高速接口(如 USB 2.0/3.0、LVDS 等),请在 系统级检测信号完整性,15 pF 电容可能影响高速链路的眼图。)
器件额定工作温度 -55℃ 至 +125℃,适用于宽温环境下长期使用。长期可靠性取决于实际脉冲能量、工作环境及焊接工艺。建议进行产品级的 ESD 与浪涌验证以确认系统可靠性。
使用前请参考厂方完整数据手册以获取详尽的峰值钳位测试条件、浪涌曲线、封装尺寸及回流焊推荐曲线。针对关键或高速接口,建议在样机阶段进行信号完整性与系统级防护验证,确保在实际工作条件下达到预期保护效果。

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.
