SMAJ30A/TR13 是 Brightking(台湾君耀)旗下的单向 TVS(二极管瞬态电压抑制器)封装为 SMA(DO-214AC)的表贴浪涌保护器。器件设计用于在瞬态过压发生时快速钳位,保护敏感电子电路免受雷击、开关瞬变及电磁兼容(EMC)事件的损害。典型应用包括 24V 直流电源线、工业控制、通讯接口及其它需要高能脉冲吸收的场合。
总结:SMAJ30A/TR13 提供 30V 反向耐压、33.3V 击穿、48.4V 钳位(在 10/1000µs 条件下)与 400W 脉冲吸收能力,兼具宽温工作范围与 SMA 封装的机械可靠性,适合各类工业与通信直流供电线路的瞬态浪涌保护。若需更具体的曲线(I-V、钳位随测试波形变化、热阻)或样品测试建议,可进一步提供电路环境与应用场景以便精准推荐。

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.
