ElecSuper(静芯微)P4SMA6.8CA是一款专为敏感电子电路设计的双向瞬态抑制二极管(TVS),核心作用是快速抑制瞬态过压(如静电放电ESD、浪涌脉冲),避免后端元件因过压损坏,广泛适配多领域电子设备的防护需求。
P4SMA6.8CA属于单路双向TVS器件,采用SMA封装(型号后缀明确标注,行业惯例中“SMA”为标准塑封小功率封装),体积紧凑(约2.7×1.6mm),适合高密度PCB布局。其设计初衷是针对低电压电路的瞬态防护,平衡了防护性能与电路兼容性,避免正常工作时对信号传输的干扰。
反向截止状态下的漏电流为400μA,属于低漏电流设计——既保证了TVS对过压的快速响应,又避免了正常工作时的额外功耗,适合对电源效率要求较高的便携式设备。
P4SMA6.8CA符合IEC 61000-4-2静电放电防护标准,双向设计可同时应对正负方向的ESD脉冲(如接触放电±8kV、空气放电±15kV),能快速(ns级响应时间)泄放静电能量,避免电路因静电击穿失效。此外,其浪涌耐受能力满足多数设备的电磁兼容(EMC)要求,无需额外增加防护元件即可通过基础浪涌测试。
总结:ElecSuper(静芯微)P4SMA6.8CA是一款高性价比的双向TVS器件,以紧凑体积、宽温范围、ns级响应时间为核心优势,适配多领域低电压电路的瞬态过压防护,是替代进口同类产品的可靠选择。

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.
