PESD3V3L1BA 是东沃(DOWO)推出的单路双向瞬态抑制器(TVS二极管),采用小型 SOD-323 封装,专为 3.3V 工作电压的信号和接口保护设计。器件在 ESD、EFT 和浪涌等瞬态冲击下提供快速钳位与能量吸收能力,适用于工业控制、通信、消费电子等需要对单条信号线进行过压防护的场合。
PESD3V3L1BA(东沃)是一款面向 3.3V 系统的单路双向 TVS 器件,具有较高的瞬态吸收能力与工业级抗扰动认证,适合用于对单条信号线的 ESD、EFT 与浪涌保护。其 SOD-323 小型封装利于贴近接口布局,但 90 pF 的较高结电容限制了在高速信号线上的应用。设计时应结合系统承受电压、信号完整性要求和重复冲击条件综合评估,并遵循靠近保护点、短回流路径的 PCB 布局原则以获得最佳防护效果。

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.
