CJSMAJ16CA是江苏长电(CJ)推出的双向瞬态抑制二极管(TVS),属于SMAG封装系列的低压防护器件。其核心定位是为16V以下直流/交流电路提供快速、可靠的瞬态过压防护,可有效抑制静电放电(ESD)、雷电感应浪涌及电路开关瞬态脉冲,适配双向极性脉冲的防护需求(无需区分正负极)。
该器件的电气参数针对低压防护场景做了精准优化,核心参数意义如下:
SMAG为表面贴装封装(SMA小型化优化版),尺寸紧凑(长3.0mm×宽1.6mm×高1.1mm),适合高密度PCB设计,适配便携式设备、汽车电子模块等小型化终端。
器件工作温度覆盖**-55℃+150℃**,满足工业级(-40℃+85℃)及汽车级(-40℃~+125℃)严苛环境,极端温度下稳定工作,无需额外散热。
双向导通设计,安装无需区分正负极,减少装配错误,提升生产效率,适配正负双向浪涌防护(如交流电路、双向信号接口)。
CJSMAJ16CA的参数特性使其广泛适配以下场景:
相较于同类低压TVS管,CJSMAJ16CA具备以下核心优势:
该器件通过了CJ内部可靠性测试(如高温老化、温度循环、机械振动等),可满足批量生产的一致性要求,是低压电路瞬态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.
