SMF15CA 是 Littelfuse(美国力特)推出的一款双向瞬态抑制二极管(TVS),封装为 SOD-123FL,专为保护敏感电子电路免受静电放电(ESD)、电快速瞬变(EFT)和浪涌脉冲侵害而设计。其额定反向工作电压(Vrwm)为 15V(亦有 16V 类似规格变种),双向结构适合交流或对称信号线的瞬态保护需求。
SOD-123FL 小型表贴封装,适用于占位受限的消费电子、通信设备与工业控制板。封装热阻较小,但由于能量吸收依赖于外部散热和走线,实际脉冲能量能力受 PCB 设计影响明显。
SMF15CA 在-65°C 至 +150°C 宽温区间内工作,适应工业级环境。产品通过 IEC 61000-4-2 与 IEC 61000-4-4 等抗扰度标准,可有效应对常见静电与电快速瞬变冲击。实际系统验证仍建议在目标应用环境中做 EMC 测试。
SMF15CA 以其 200W(10/1000μs)峰值功率、低漏电与小型 SOD-123FL 封装,为中低能量瞬态保护提供了紧凑且可靠的方案。适用于多种工业、通信与消费电子场合,尤其在空间受限且需要双向保护的接口或电源线上具有显著优势。选型时应结合系统电压、脉冲能量与 PCB 布局综合考虑,以确保长期稳定防护效果。

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.
