SMBJ30A/TR13 是台湾君耀(Brightking)生产的一款单向瞬态电压抑制器(TVS),专为对直流线路和敏感电子元件提供瞬态过压保护而设计。该器件采用SMB(DO‑214AA)表面贴装封装,能够在受雷击、开关瞬态或静电放电等瞬态事件时快速钳位电压,保护下游电路免受损坏。SMBJ30A/TR13 支持卷带(/TR13)包装,便于自动贴片生产线的大批量装配。
SMB(DO‑214AA)封装为常用的中功率表贴封装,具备较低的热阻和较大的焊盘面积,利于热量扩散与PCB散热设计。器件适用于标准回流焊工艺,但建议按照厂商数据手册的焊接温度曲线执行,以避免过热导致封装或电性能的退化。卷带包装(/TR13)适合高速贴装,降低生产损耗并提高装配效率。
总结:SMBJ30A/TR13 以其 30 V 的反向工作电压、600 W 的峰值功率能力、以及小于 1 μA 的低漏电流,为中功率直流供电系统提供可靠、快速的瞬态过压保护,适用于自动化贴片生产与多种工业与消费类场景。选用时请结合实际脉冲波形、环境温度与布局条件,并参照厂商完整数据手册进行最终验证。

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.
