SMF26A 是晶导微电子推出的一款瞬态电压抑制(TVS)二极管,采用 SOD-123FL 表面贴装封装,专为抑制电源线和信号线上突发过压、浪涌与电磁干扰而设计。器件在宽温度范围内保持可靠工作(-55℃ 至 +150℃),适用于工业、通讯、自动化等需要对 24V 及相近电压轨道进行浪涌保护的场景。
这些参数表明 SMF26A 能在瞬态脉冲(10/1000 μs 波形)下提供 200W 的抑制能力,同时在峰值脉冲电流 4.8A 时将钳位电压控制在约 42.1V,从而保护下游电路免受高压冲击。
总结:SMF26A(晶导微电子)是一款面向 24V 级电源与信号线的高能量 TVS 器件,以其 200W 的瞬态吸收能力、低漏电以及宽温度范围,适合工业、通信与受限空间的电路保护需求。在实际设计中,合理布局与配套保护措施能显著提升系统的抗浪涌性能和长期可靠性。若需详细的典型参数曲线、封装尺寸和焊盘建议,请参考晶导微电子的器件数据手册。

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.
