CJSMAJ11CA是江苏长电(CJ)推出的双向瞬态抑制二极管(TVS),专为低压电路的浪涌过压防护设计。其核心作用是在电路遭遇瞬态浪涌(如静电放电、感应雷击、开关瞬态等)时,快速从高阻态切换至低阻态,将电压钳位在安全范围内,避免后端敏感电子元件(如MCU、传感器、接口芯片等)因过压损坏,是电子设备抗干扰防护的关键器件之一。
该器件的电气参数经过优化,适配11V左右的低压系统,核心参数及意义如下:
CJSMAJ11CA采用SMAG封装(长电自有封装型号,对应国际标准SOD-323封装),具有以下优势:
该器件因双向防护、低钳位电压等特性,广泛应用于以下场景:
CJSMAJ11CA由江苏长电科技(CJ) 生产,长电作为国内半导体封装测试龙头企业,具有以下优势:
总结:CJSMAJ11CA是一款高性价比的双向TVS管,兼具小型化、双向防护、低漏电流等优势,适配11V左右低压系统的过压防护需求,是消费电子、工业控制等领域的可靠选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
