SMAJ130CA 瞬态抑制二极管（TVS）产品概述
一、产品核心定位与应用价值
SMAJ130CA是一款双向瞬态抑制二极管（TVS），专为电路瞬态过压防护设计。其核心作用是在电路遭遇雷击、开关浪涌、静电放电（ESD）等高压冲击时，快速响应并钳位电压，避免后端敏感元件（如MCU、传感器、IC）因过压损坏，是电子设备过压防护体系的关键组件。
二、关键电气参数深度解析
SMAJ130CA的参数针对120V级电压场景优化，核心指标如下：
- 反向截止电压（Vrwm=130V）
正常工作时反向可承受的最大直流电压，此时器件截止，漏电流仅5μA，不影响电路正常供电。 - 击穿电压（Vbr=144V）
反向电压超144V时器件击穿进入低阻态，是“截止→钳位”的过渡阈值，确保浪涌到来时快速响应。 - 钳位电压（Vc=209V）
峰值脉冲电流（1.9A）下的最大电压，是保护核心——后端器件耐压需高于209V才能被有效防护。 - 峰值脉冲功率（Ppp=400W）
单次可承受的最大瞬态功率，对应1.9A脉冲电流的能量吸收能力，可应对常见雷击浪涌（1.2/50μs波形）。 - 双向极性
正反方向均能保护，无需区分电路极性，简化安装设计，适配无明确极性的电源/信号线路。
三、封装特性与适用场景
SMAJ130CA采用SMAG表面贴装封装，具备以下优势：
- 尺寸紧凑：适配高密度PCB布局，适合便携设备、小型家电等空间受限场景；
- 焊接便捷：兼容自动贴片机生产，提高生产效率；
- 散热性佳：封装结构利于瞬态热量扩散，保障脉冲冲击后的可靠性。
典型应用场景：
- 电源线路防护：110V/120V交流电源输入（整流后直流≈150V，适配Vrwm=130V）；
- 工业控制：PLC、传感器模块的电源/信号端口，抵御现场浪涌；
- 消费电子：智能家居控制器、小型家电控制电路，应对开关浪涌；
- 通信设备：部分高电压信号线路的过压防护（双向极性适配无极性信号）。
四、品牌与可靠性保障
SMAJ130CA由江苏长电（CJ） 生产，长电是国内知名半导体厂商，产品通过多项可靠性测试：
- 符合RoHS环保标准，无铅焊接兼容；
- 经过脉冲寿命测试（重复浪涌冲击），保障长期稳定性；
- 温度范围覆盖工业级（-55℃~+150℃），适应宽温环境。
五、选型与使用注意事项
- 电压匹配：后端器件耐压需高于钳位电压209V，避免保护失效；
- 功率裕量：浪涌功率较大时，可并联多个器件提升总吸收能力；
- 安装位置：尽可能靠近被保护器件输入端口，减少线路寄生电感影响；
- 极性确认：双向器件无需区分正负，但需确认电路电压不超Vrwm=130V。
综上，SMAJ130CA凭借双向防护、紧凑封装与可靠性能，成为120V级电路过压防护的高性价比选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
