SMAJ26CA 是 MSKSEMI(美森科)出品的一款双向瞬态电压抑制器(TVS),采用 SMA 表面贴装封装,专为抑制瞬态浪涌和过电压事件设计。该器件在 10/1000µs 浪涌波形下能承受峰值脉冲功率 400W,适用于工业电源、通信设备、信号线和24V等级系统的浪涌防护。
SMA 为常见的表面贴装封装,建议严格按照厂商推荐的 PCB 焊盘与回流焊工艺进行放置。器件在工作时会将浪涌能量转化为热量,建议在高浪涌场合留有适当的铜箔散热区域并避免周围热敏元件紧邻。双向器件无极性方向性,安装时注意机械定位标识即可。
在设计验证阶段建议对目标系统进行浪涌模拟测试(10/1000µs 或 IEC 标准波形)以确认钳位电压与后端电路的安全裕量;同时进行多次循环测试以评估器件在重复浪涌下的稳定性。对关键产品建议结合温度应力测试与长期老化验证,保证在实际工作环境中的可靠防护性能。
综上,SMAJ26CA 是一款针对 24V 级别及双向保护场景的高能量吸收 TVS,适合在工业与通信等需抵抗瞬态浪涌的应用中作为前端过压保护器件选用。

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.
