SDA1211CDN 是 Leiditech(雷卯电子)推出的一款单路瞬态抑制二极管(TVS),封装为 DFN1006,专为保护敏感电子接口免受静电放电(ESD)和雷电浪涌(Surge)冲击而设计。器件标称反向工作电压(Vrwm)为 12V,具有低结电容(Cj ≈ 30pF)和极低的反向漏电流(Ir ≈ 0.2μA),适合保护对带宽和静态电流要求较高的信号线与供电线路。
总结:SDA1211CDN 是一款面向 12V 类系统的高性能单路 TVS 二极管,具备低结电容、低漏电流与较强的 8/20μs 浪涌吸收能力,适用于对体积、带宽与静态功耗有较高要求的工业与汽车电子接口保护场合。购买与设计使用前,建议结合具体系统的浪涌能量、重复脉冲情况与热管理方案进行评估。

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.
