SMAJ10CA 产品概述

一、产品简介

SMAJ10CA 为双向瞬态电压抑制二极管(TVS),由 CJ(江苏长电/长晶)生产,采用 SMAG(SMA)封装,针对瞬态过压和浪涌保护设计。其额定反向工作电压(Vrwm)为 10V,典型钳位电压 17V,击穿电压约 12.3V,适用于 12V 类电源系统及信号线的浪涌防护。

二、主要电气参数

  • 极性:双向(Bi-directional),可在正负极性冲击下吸收能量,适合交流或双向脉冲场合。
  • 反向截止电压(Vrwm):10V。
  • 击穿电压(Vbr):12.3V。
  • 钳位电压(Vc):17V(典型值,具体见曲线)。
  • 峰值脉冲电流(Ipp):23.5A @ 10/1000µs(浪涌电流能力)。
  • 峰值脉冲功率(Ppp):400W @ 10/1000µs。
  • 反向漏电流(Ir):5µA(在 Vrwm 下)。
  • 工作温度范围:-55℃ ~ +150℃。

三、产品特性与优势

  • 高能量吸收:10/1000µs 波形下 400W 峰值功率和 23.5A 峰值电流,能有效钳位工业和汽车级瞬态脉冲。
  • 低漏电流:5µA 等级,减少静态功耗,对敏感电子电路影响小。
  • 宽工作温度:-55℃ 至 +150℃,可适应严苛环境。
  • 双向保护:无需区分极性,简化电路设计,适用于 AC 或双向浪涌场合。
  • 标准 SMA 封装:便于表面贴装,兼容自动化贴片工艺。

四、典型应用

  • 汽车电源和车载电子保护(12V 系统)。
  • 电源输入、DC 线路、逆变器和变换器的浪涌抑制。
  • 通信设备、电源模块、工业控制器及配电系统的过压保护。
  • 数据和信号线路需要双向钳位的场合。

五、选型与使用建议

  • 确认工作电压:Vrwm=10V 适合 12V 左右系统;若系统持续电压高于 Vrwm,应选用更高 Vrwm 的型号。
  • 考虑能量和波形:本器件对 10/1000µs 浪涌有良好吸收能力,若需对抗 IEC 61000‑4‑5 等不同波形,应进行实际浪涌测试验证。
  • 布局建议:放置在靠近被保护端口处,短走线、宽铜带以降低感抗并便于散热。必要时配合熔断器、串联电感或滤波器组合使用,增强整体抗浪涌能力。
  • 热管理:高能量吸收时封装及 PCB 会产生热量,需保证散热通路和足够铜面积。

六、存储与可靠性提示

  • 存放于干燥环境,避免潮湿和腐蚀性气体。
  • 在焊接和回流工艺中遵循封装供应商的建议,控制焊接温度和时间以保证可靠性。
  • 出现严重多次冲击后建议更换器件以确保保护性能。

SMAJ10CA 以其稳定的钳位特性、较低漏电和较高浪涌吸收能力,适合要求可靠瞬态保护的 12V 类电源与信号线路,是工程应用中常用的 TVS 保护器件之一。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
