SMAJ6.0CA-AT/TR13 产品概述

一、主要特性

SMAJ6.0CA-AT/TR13 是 Brightking(台湾君耀)推出的一款双向瞬态抑制二极管(TVS),专为表面贴装(SMA,DO-214AC)应用设计。器件具有低外形、低电感与玻璃钝化结结构,能够在受瞬态过电压冲击时提供快速且稳定的钳位保护。主要特性包括:

  • 双向极性,适用于交流或双向信号线保护;
  • 反向截止电压 Vrwm = 6V,击穿电压 VBR ≈ 6.67V;
  • 钳位电压 Vc ≈ 10.3V(在规定浪涌条件下);
  • 峰值脉冲电流 Ipp = 38.8A;峰值脉冲功率 Ppp = 400W(10/1000 µs 波形,重复率/占空比 0.01%);
  • 反向漏电流 Ir = 800 µA;工作温度范围 -55℃ 至 +150℃;
  • 符合 IEC 61000-4-2 防护等级,适配 ESD 防护要求。

二、典型技术参数

  • 类型:双向 TVS 二极管
  • 工作电压(Vrwm):6V
  • 击穿电压(VBR):6.67V(典型/标称值,按标准测试条件)
  • 钳位电压(Vc):10.3V(在 10/1000 µs 浪涌下测得)
  • 峰值脉冲电流(Ipp):38.8A
  • 峰值脉冲功率(Ppp):400W @ 10/1000 µs,重复率 0.01%
  • 反向电流(Ir):800 µA(在 Vrwm 条件下)
  • 工作温度:-55℃ ~ +150℃
  • 封装:SMA (DO-214AC),适合自动贴装与回流焊工艺

三、封装与工艺优势

SMAJ6.0CA-AT/TR13 采用低轮廓 SMA 表贴封装,便于电路板空间优化与高速自动化生产。玻璃钝化结工艺提升了器件的热稳定性和长期可靠性;低电感特性使其在高频或快速脉冲事件下能够更有效地抑制尖峰,减少对相邻电路的干扰。适合贴片回流焊,建议按厂商提供的回流温度曲线与焊接工艺规范进行。

四、适用场景

  • I/O 接口保护:USB、RS-485、串口与各类数据通信口的浪涌与静电防护;
  • AC / DC 电源线防护:为小功率电源、开关电源输入端提供瞬态浪涌抑制;
  • 工业设备与消费电子:工业控制器、仪表、机顶盒、路由器等需抗电磁脉冲与静电冲击的场合;
  • 需要双向保护的信号线或非极性电源线路。

五、性能优势与设计注意事项

  • 优势:高达 400W 的峰值吸收能力(10/1000 µs),在规定占空比下可有效钳位高能量瞬态;双向结构无需考虑方向性,便于对交流或对称信号保护;低感抗、低外形适合高速信号布局。
  • 注意事项:
    • 该器件的峰值功率基于特定波形与占空比(10/1000 µs,0.01%),不适合长期或重复的大能量冲击;
    • 反向漏电流 Ir 约 800 µA,应在低功耗或高精度检测电路中评估对系统的影响;
    • 布板时建议在受保护对象附近放置 TVS,减小走线电感,并在必要时配合串联阻抗或熔断器提高整体保护级别;
    • 热管理:在高能量吸收事件后器件会产生热量,需考虑到附近元件的热耐受性与散热路径。

六、可靠性与标准认证

器件通过 IEC 61000-4-2 等静电放电规范的防护等级测试,适用于对 ESD 要求较高的应用场景。玻璃钝化结与 SMD 结构提高了抗冲击性与长期稳定性。推荐在批量生产前进行针对应用场景的浪涌与温度应力测试验证。

七、典型安装与应用建议

  • 布局:尽量靠近被保护端子或接口放置,走线短且宽,以降低串联电感;
  • 焊接:采用标准回流焊工艺并遵循制造商的温度曲线;
  • 搭配:在高能量场合可与串联电阻、磁珠或熔断器联合使用,形成多级保护;
  • 测试:在设计验证阶段使用 10/1000 µs 浪涌波形验证钳位电压与剩余电压,评估对系统的冲击。

总结:SMAJ6.0CA-AT/TR13 提供了在紧凑尺寸下优秀的瞬态能量吸收与快速钳位能力,适合对 I/O 接口与电源线进行经济可靠的防护。根据具体系统功耗、漏电容与热管理要求,合理布板与测试可以获得最佳保护效果。若需更详细的电气特性曲线或回流焊工艺资料,建议联系 Brightking(台湾君耀)获取完整规格书。
