SMFJ24A 为 BORN(伯恩半导体)推出的单向瞬态电压抑制器(TVS),专为 24V 级别电源与信号线提供静电(ESD)和浪涌(Surge/EFT)保护。器件封装为 SOD-123FL,体积小、安装方便,适合空间受限的表贴电路板设计。符合 IEC 61000-4-2(静电放电)与 IEC 61000-4-4(脉冲群)防护要求。
以上参数表明在标准 10/1000 μs 浪涌测试下,器件能承受 200W 能量并将浪涌电流钳位到约 38.9V,适合保护 24V 系统的过电压瞬态。
SOD-123FL 提供低剖面、小占板面积的封装优势;为发挥最佳保护效果,建议:
SMFJ24A 满足 IEC 61000-4-2 与 IEC 61000-4-4 等电磁兼容抗扰度规范,适用于需要通过 ESD 与 EFT 测试的产品。为保证系统级可靠性,建议在系统层面进行整机级冲击测试与长期寿命验证。
总结:SMFJ24A(BORN)以 24V 工作电压、200W 峰值脉冲功率和小型 SOD-123FL 封装,为工业与通信类 24V 线路提供高效、紧凑的静电与浪涌保护方案。在实际应用中,合理的 PCB 布局与能量管理可以显著提高保护效果与器件寿命。

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.
