PTVSHC3D7VU 为 Prisemi(芯导)出品的一款单通道单向瞬态抑制二极管(ESD TVS),封装为 SOD-323。器件针对瞬态电压冲击和静电放电(ESD)保护而设计,提供快速钳位响应并满足工业级抗扰度测试标准,适用于对空间有严格要求的表面贴装保护方案。
注意:由于结电容约 500 pF,本器件对高速差分或高带宽信号(例如 USB3.0、HDMI、PCIe 等)会造成信号失真或带宽下降,不建议用于高速信号线的直接保护。
对于单向型号,建议按下列方式连接:将二极管阳极接地,阴极接被保护的信号线/电源线上(即常态为反向偏置)。在正常工作电压下二极管呈高阻抗;当瞬态电压超过 Vrwm 或击穿点时迅速导通,将过压钳位到 Vc 附近并导入地线,从而保护后端电路。若需要双向保护,应选用对应的双向型号或并联两只单向器件并注意封装和布局。
PTVSHC3D7VU 适合需要单通道、单向保护且对板面空间敏感的低速信号及供电口。若应用涉及高速信号或需更低结电容,请选择专为高速接口设计的低容 TVS 器件。采购时请向正规代理或厂商索取最新器件规格书、RoHS/REACH 证明及样片测试数据,以确保参数满足具体应用需求。

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.
