PTVSHC1DF7VBH 是 Prisemi(芯导)推出的一款单路、双向瞬态抑制二极管(TVS),采用 SOD-123F 小封装,专为瞬态浪涌与静电放电(ESD)保护设计。器件响应速度快、耐脉冲能力强,适用于对电源轨和信号线的过压过冲保护。
SOD-123F 小型表面贴装封装利于 PCB 布局密集化。由于封装热阻和寄生参数限制,器件适合承受短时单次脉冲(8/20 μs)能量;在频繁或多次大能量冲击场合,应按系统级方案(加入熔断器、限流电阻或更高功率 TVS)进行等级提升。产品通过 IEC 61000-4-2/4-4 抗扰度验证,满足常见工业和消费级抗干扰需求。
如需样品参数曲线(钳位曲线、漏电随温度变化等)、PCB 布局参考或替代型号比较,我可以继续提供更详细的资料与设计建议。

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.
