CJSMAJ64A是江苏长电/长晶(CJ品牌) 推出的单向瞬态抑制二极管(TVS),核心作用是快速抑制电路中的瞬态过压(如雷击感应、电源浪涌、静电放电等),避免敏感电子元器件(如芯片、电容、传感器)因过压损坏。该器件采用SMAG贴片封装,体积紧凑,适配小型化、高密度电子设备的设计需求,是低中压电路过压防护的常用器件之一。
CJSMAJ64A的关键参数明确,覆盖多数低中压应用的防护要求:
该器件采用SMAG贴片封装,属于小型表面贴装封装(常规尺寸约2.0×1.2×1.0mm),适配自动贴装生产线,适合高密度PCB布局。
典型应用场景包括:
以路由器电源端口防护为例:路由器电源输入为12V/1A,若遭遇雷击感应或电源浪涌,瞬态电压可能飙升至100V以上。CJSMAJ64A并联在电源端口与地之间,当浪涌电压超过78.54V击穿电压时,器件快速导通,将电压钳位在102V以下,避免电源芯片、滤波电容损坏,确保路由器稳定运行。
CJSMAJ64A凭借可靠的防护性能、紧凑封装及稳定质量,成为低中压电路过压防护的高性价比选择。

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.
