SMBJ400A/TR13 为 Brightking(台湾君耀)出品的一款单向瞬态电压抑制二极管(TVS),采用 SMB(DO-214AA)封装,专为工业级高压直流与交流保护设计。器件在正常工作状态下对反向电压具备高耐受性,并能在瞬态过压事件发生时以低阻抗路径快速钳位,保护后端敏感电子器件免受浪涌与雷击冲击。
SMBJ400A/TR13 是一款面向高压应用的单向 TVS,凭借 400 V 的反向额定电压、600 W 的脉冲吸收能力及宽温工作范围,适用于工业、电力与通信等需高压瞬态保护的场景。在实际设计中,建议结合具体脉冲波形、散热条件与安装方式进行选型与验证,以确保长期稳定可靠的保护效果。若需详细的脉冲测试曲线、典型钳位随电流变化图或封装尺寸图,可向 Brightking 获取完整数据手册。

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.
