SMAJ6.0A 产品概述

一、产品简介

SMAJ6.0A 是 GOODWORK(固得沃克)推出的一款单向瞬态电压抑制器(TVS),采用先进的 GPP 工艺芯片制造,封装为工业常用的 SMA(DO-214AC)。器件专为抑制瞬态过压、保护电子系统免受浪涌与瞬态脉冲损伤而设计,具备低漏电、高对档率及良好的高温可靠性,适合工业、汽车电子、通信、电源与消费类电子等多种应用场景。

二、主要电气参数

  • 类型:TVS,单向(单极性)
  • 反向工作电压 Vrwm:6.0 V
  • 击穿电压 VBR(典型):6.67 V
  • 钳位电压 Vc:10.3 V(在额定峰值脉冲条件下测得)
  • 峰值脉冲电流 Ipp:38.8 A
  • 峰值脉冲功率 Ppp:400 W(标准脉冲条件)
  • 反向漏电流 Ir:800 μA
  • 工作温度范围:-55 ℃ 至 +150 ℃
  • 封装:SMA (DO-214AC)
  • 品牌:GOODWORK(固得沃克)

以上参数为器件典型/标称值,具体数值应以器件数据手册为准并参考测试条件(如脉冲波形、持续时间及环境温度)。

三、产品特点

  1. 高效浪涌抑制能力:400 W 峰值脉冲功率和 38.8 A 峰值脉冲电流,能有效吸收来自感性负载开关、线路雷击及静电放电产生的瞬态过电压。
  2. 低漏电流:GPP 工艺实现了较低的反向漏电流(Ir ≈ 800 μA),在待机与低功耗系统中减小能耗影响。
  3. 精确的电压钳制:钳位电压 10.3 V 能在过压事件中将电压限制在安全范围,保护下游元件免遭损坏。
  4. 宽温度适应性:-55 ℃ 至 +150 ℃ 的工作温度范围,适用于高温工作环境和对可靠性要求较高的应用。
  5. 封装可靠、易于量产:SMA(DO-214AC)为成熟封装,便于波峰/回流焊加工及自动化贴装。

四、典型应用场景

  • 汽车电子:车载电源总线、点火系统、车灯与车载通信模块的浪涌保护(需注意汽车规范要求和额外认证)。
  • 工业控制:PLC、驱动模块、传感器接口及现场总线防护。
  • 通信设备:基站、路由器、交换机的电源与接口防雷击、浪涌。
  • 电源管理:开关电源输入、DC-DC 模块及电池保护電路的瞬变抑制。
  • 消费电子:充电器、适配器、USB 与信号线防护。

五、封装与可靠性

SMA(DO-214AC)封装提供良好的机械强度和散热路径,适合流水线生产。器件采用 GPP 工艺芯片,提升了高温稳定性与长期可靠性。建议在设计时遵循制造商推荐的焊盘尺寸与焊接曲线,以确保焊接质量与热循环可靠性。

六、使用建议与注意事项

  • 布局与接地:为获得最佳保护效果,应将 TVS 器件尽可能靠近被保护的输入端或接口,并保证到系统地(GND)的回流路径短且粗,以减少串联感抗与电压振铃。
  • 热管理:在多次高能脉冲或长时间苛刻工况下,注意器件温升与系统散热,必要时在 PCB 上预留散热区或采用更高功率等级的保护器件。
  • 极性识别:本器件为单向 TVS,正向工作与反向钳位特性需要在电路中正确接线;错误接入可能导致无法提供预期保护或器件毁坏。
  • 测试条件匹配:在评估钳位电压与能量吸收能力时,应保证测试脉冲波形与实际工况匹配(典型行业采用 8/20 μs 或 10/1000 μs 波形),并参考器件数据手册的具体说明。
  • 选型注意:若被保护回路对漏电流极其敏感或有更高的峰值能量需求,应考虑更低漏电或更高 Ppp 等级的型号,或采取并联/串联等组合方案。

七、结论

SMAJ6.0A(GOODWORK)是一款面向广泛工业与商用场景的单向 TVS,凭借 GPP 工艺带来的低漏电、高对档率与优良高温稳定性,以及 SMA 封装的通用性,能够为中低压系统提供可靠、高效的瞬态过压保护。在实际应用中,通过正确的 PCB 布局与热管理,可以充分发挥其抗浪涌与钳位保护能力,提升系统整体可靠性。若需量产选型或索取详细数据手册与焊盘建议,请联系 GOODWORK 或其授权经销渠道。

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.
