PSD05C-ES 是 ElecSuper(静芯微)推出的一款单路双向静电放电(ESD)保护器件,采用 SOD-323 小型封装。器件针对接口与信号线的瞬态过压保护设计,能够在高能脉冲冲击下快速钳位,保护后端电路免受损坏;工作温度范围宽(-40℃至+125℃),适应多种环境条件。
PSD05C-ES 适合用于各类需要对单根信号线进行双向瞬态保护的场合,包括但不限于:按键/触摸接口、控制信号线、低速串行接口、通用 IO 端口、消费电子、移动设备外围接口、工业控制模块以及需要符合 IEC 61000-4-2 静电防护要求的设备前端防护。
SOD-323 封装体积小,便于高密度 PCB 布局。为获得最佳防护效果,建议器件尽可能靠近受保护的连接器或接口焊装,缩短输入引线长度以降低寄生电感;保护器地端应采用低阻抗接地处理,必要时在保护器附近布置过孔接地,保证回路最短、阻抗最低。
双向 ESD 抑制器通常以两端并联方式连接于信号线与地之间:当信号出现正向或负向瞬变时,器件进入导通钳位状态,将能量快速导入地线,从而保护后级电路。布线时应保证接地回路短且低阻。
总结:PSD05C-ES 提供可靠的单路双向 ESD 防护,适用 5 V 级别接口及一般工业/消费电子环境。选用时应综合考虑钳位电压、结电容与系统信号速率,以确保在满足防护要求的同时不影响信号完整性。

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.
