SMF22A-TP 是 MCC(美微科)推出的一款单向瞬态电压抑制二极管(TVS),采用表面贴装 SOD-123FL 封装,专为在瞬态过电压、雷击和静电放电事件中对电源和信号线提供钳位保护而设计。其典型参数包括:反向工作电压 Vrwm = 22V,击穿电压 VBR = 26.9V,钳位电压 Vc = 35.5V(在指定脉冲条件下),峰值脉冲电流 Ipp = 5.6A,峰值脉冲功率 Ppp = 200W(10/1000 μs 波形),反向泄漏电流 Ir ≈ 1 μA(常温),工作温度范围 -65℃ ~ +175℃,满足 IEC 61000-4-2 静电放电防护要求。
SMF22A-TP 使用 SOD-123FL 表面贴装封装,适合自动贴片生产工艺。器件额定工作温度宽,适用于工业级环境。符合 IEC 61000-4-2 的 ESD 防护能力,且在典型的浪涌测试条件(10/1000 μs)下能提供 200W 的脉冲能量吸收能力。针对具体可靠性与寿命评估,建议参考厂商完整的器件规范书与应用说明,结合实际工作脉冲分布进行验证。
总结:SMF22A-TP 是一款面向工业与通讯接口的高能量单向 TVS 二极管,凭借 22V 反向工作电压、35.5V 钳位电压和 200W 的脉冲能力,在 SOD-123FL 紧凑封装下为电源与信号线提供高效、可靠的瞬态过压保护。欲获得器件的完整电气特性与应用建议,请参照 MCC 官方技术资料。

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.
