SMBJ15A是友台半导体(UMW) 推出的单向瞬态抑制二极管(TVS),属于过压防护领域的基础器件,主要用于抑制电路中因静电放电(ESD)、电快速瞬变脉冲群(EFT)、雷击感应等产生的瞬态高压脉冲,保障后端敏感电子元器件(如MCU、传感器、通信模块)的正常工作与可靠性。
SMBJ15A的核心参数围绕“瞬态防护能力”与“常态兼容性”设计,具体如下:
SMBJ15A采用SMB封装(DO-214AA),属于表面贴装型封装,物理尺寸约为2.9mm(长)×5.2mm(宽)×1.6mm(高),具备以下优势:
SMBJ15A通过了IEC 61000-4-4(电快速瞬变脉冲群) 和IEC 61000-4-2(静电放电) 标准认证,具体防护能力:
结合参数与防护能力,SMBJ15A适用于以下低电压电路防护:
SMBJ15A凭借“低漏电流、高防护能力、小体积”的特点,成为低电压电路瞬态防护的高性价比选择,广泛应用于消费电子、工业、通信等领域。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
