SMAJ6.0CA 双向 6V / 400W SMA 封装 TVS 二极管 — 产品概述

一、产品概述

SMAJ6.0CA 是 Hottech(合科泰)推出的一款双向瞬态电压抑制(TVS)二极管,採用常见的 SMA 表面贴装封装,面向对抗雷击、开关电弧、电源浪涌等瞬态过电压的保护场合。典型应用为电源线、通信接口及其它对称线路(如双向信号线、交流供电线路)上的浪涌钳位保护。该器件在 10/1000 μs 浪涌波形下可提供 400W 峰值脉冲功率能力,具有快速响应和稳定的钳位特性。

二、关键参数

  • 极性:双向(Bidirectional)——对称钳位,适用于交流或反向可能出现的线路。
  • 反向截止电压 Vrwm(工作稳压电压):6 V(器件在正常工作状态下的最大持续电压)。
  • 钳位电压(典型):10.3 V @ Ipp(在 10/1000 μs 浪涌条件下)。
  • 峰值脉冲电流 Ipp:38.83 A(对应 400 W @ 10/1000 μs 的脉冲功率)。
  • 峰值脉冲功率 Ppp:400 W(以 10/1000 μs 标准波形测得)。
  • 击穿电压 VBR:7.37 V(器件进入雪崩区的典型电压)。
  • 反向电流 Ir:800 μA(在 Vrwm 条件下的最大反向漏电流)。
  • 工作温度范围:-55 ℃ ~ +150 ℃。
  • 类型:TVS(瞬态电压抑制器)。
  • 封装:SMA(表面贴装,便于自动贴装与回流焊工艺)。
  • 品牌:Hottech(合科泰)。

三、特性与优势

  • 高脉冲抑制能力:在 10/1000 μs 浪涌波形下可承受 400 W 峰值功率,能有效缓解雷击与大能量浪涌。
  • 双向结构:对称钳位特性使其在交流或有反向冲击的线路中使用更加安全可靠,无须区分极性。
  • 低钳位电压:典型钳位电压约 10.3 V,能在浪涌时将过电压钳制到较低水平,保护下游器件。
  • 宽工作温度:-55 ~ +150 ℃ 的工作范围,适合工业级环境。
  • SMA 小体积封装:便于在空间受限的设计中安装,并兼容标准 SMT 工艺。

四、典型应用场景

  • 工业电源输入与直流供电总线保护(6 V 等级电源 rails)。
  • 通信接口保护(如对 6 V 等级供电的串口、接口线的浪涌防护)。
  • 汽车电子中对低压辅助线路的瞬态保护(根据系统要求确认符合车规标准)。
  • 电池管理、充电器以及便携设备的输入端瞬态抑制。
  • 任何需双向浪涌钳位保护且可接受约 10 V 钳位电压的应用。

五、使用与布局建议

  • 贴近受保护端口布局:将 SMAJ6.0CA 尽可能靠近被保护的插口或器件,以最小化导线/走线感应和串联阻抗。
  • 最小化串联电感:走线长度与回路面积应尽量减小,以提升钳位效率并减少电压尖峰。
  • 熔断与电流路径考虑:虽然器件能承受高能量脉冲,但若系统中存在持续大电流,应辅以合适的保险丝或限流设计以保护 TVS 本体与系统。
  • 焊接工艺:SMA 为常规回流焊兼容封装,请按推荐回流曲线进行焊接,避免超温或超时导致器件应力。
  • 双向器件无需考虑极性,但请按封装标识正确放置以便检修。

六、安全与可靠性提示

  • 非连续导通器件:TVS 设计用于瞬态事件保护,不适合长期连续承载高电流或作为稳压元件使用。
  • 温度影响:漏电流与参数随温度上升而增加,设计时应考虑最坏工况(高温下的漏电与钳位变化)。
  • 多次冲击耐受:器件的耐冲击次数受每次浪涌能量与环境条件影响,关键设备建议进行系统级浪涌仿真与寿命评估。
  • 测试条件:钳位电压、击穿电压等参数基于标准测试条件(例如 10/1000 μs 浪涌或特定测试电流),实际应用中请参考器件具体数据手册以获取完整电气特性与测试条件。

七、采购与封装信息

  • 型号:SMAJ6.0CA(Hottech/合科泰)
  • 封装:SMA 表面贴装,适配自动贴装与回流焊流程。
  • 在选型时,请结合系统最大允许钳位电压、冲击能量、电路保护策略(是否需配合熔丝/限流器)及环境温度范围,确认该型号能满足长期可靠性需求。若需更详细的电气曲线、包装规格或可靠性认证(如温度循环、冲击测试等),建议向供应商索取完整的器件数据手册与样品进行验证测试。

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.
