SMF12CA 是一款双向瞬态抑制二极管(TVS),用于对静电放电(ESD)、浪涌、电气快速瞬变等过压瞬态进行钳制和吸收保护。器件由扬杰(YANGJIE)生产,采用小型 SOD-123 封装,适合对体积、成本有要求的工业及民用电子设备,用于保护单线或差分信号线、电源线及接口电路,确保被保护电路在瞬态冲击下不被损坏。
注:钳位电压与峰值脉冲电流相关,上述 19.9 V 常为在规定脉冲电流条件下的典型钳位值。实际应用中钳位值会随浪涌幅度及环境温度变化。
SMF12CA(YANGJIE)凭借 12 V 的工作电压、约 19.9 V 的钳位和在 10/1000 μs 条件下约 10 A 的冲击电流承受能力,适用于多数 12 V 级别电源与信号线的瞬态保护场合。SOD-123 小封装便于紧凑布局,同时工作温度范围与低漏电流特性使其在工业与消费电子中具有较好通用性。最终选型请结合被保护电路的最大允许钳位、实际浪涌波形与能量要求,并以详细器件数据手册为准进行设计与热、冲击验证。

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.
