SMF22CA 是晶导微电子推出的一款 TVS(瞬态电压抑制)二极管,封装为 SOD-123FL,适用于表面贴装自动化生产。该器件专为抑制瞬态浪涌、浪涌电压钳位及保护敏感电子元件而设计,兼具响应速度快、钳位电压低和漏电流小等特点,适合工业、通信与车载等需要过压防护的场合。
这些参数共同决定了 SMF22CA 在面对短时高能脉冲(如雷击、电源开关瞬变、继电器反向尖峰)时的保护性能与适用电压范围。
SOD-123FL 封装具有体积小、低剖面、引脚热阻小等优点,适合贴片工艺。封装便于在空间受限的电路板上布局,同时能通过合理的铜箔面积扩展散热路径。器件的最大结温可达 +150℃,满足工业和车规级温度要求。
SMF22CA(SOD-123FL)凭借 22V 工作电压、35.5V 钳位电压、5.6A/200W 的脉冲能量处理能力及低漏电流等特性,是一款适合工业与车载等场合的高性价比 TVS 保护元件。合理的 PCB 布局与配套防护措施能充分发挥其瞬态抑制效果,提升系统整体的抗扰度与可靠性。
如需器件数据手册、封装尺寸或应用电路范例,可进一步提供,我可根据具体应用给出更详细的选型与布局建议。

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.
