SMAJ16CA/TR13 产品概述

一、产品简介

SMAJ16CA/TR13 是台湾君耀(Brightking)出品的一款双向瞬态电压抑制二极管(TVS),封装为SMA(DO‑214AC)。器件在直流或交流瞬态过电压事件中提供快速钳位保护,适用于数据线、通信接口、开关电源和一般电子设备的浪涌抑制。器件额定反向稳定工作电压(Vrwm)为16V,典型击穿电压为17.8V,显示出稳定的浪涌承受能力和精确的钳位特性。

二、主要电气参数

  • 极性:双向(无极性,适合交流或双向浪涌抑制)
  • 反向截止电压 Vrwm:16V
  • 击穿电压(Vbr):约 17.8V
  • 峰值脉冲电流 Ipp:15.4A(在额定脉冲条件下)
  • 峰值脉冲功率 Ppp:400W(标准脉冲条件下额定能量吸收能力)
  • 钳位电压:约 26V(在额定脉冲电流条件下)
  • 反向漏电流 Ir:≤1 μA(在 Vrwm 条件下)
  • 工作温度范围:-65 ℃ ~ +150 ℃

三、功能特点

  • 响应快速,能在纳秒级别钳制瞬态电压峰值,保护后级敏感元件;
  • 低漏电流设计,保持电路在静态工作时的低功耗;
  • 高峰值脉冲功率(400W)和较高的峰值脉冲电流,具备良好的能量吸收能力;
  • 双向结构,便于对交流回路或可能出现正负极性瞬态的信号线进行保护;
  • 宽工作温度范围,适应工业级和高温环境。

四、典型应用场景

  • 电源输入防护(开关电源、适配器输入端);
  • 通信设备接口保护(以太网、RS‑232/RS‑485 等);
  • 汽车电子和车载充电设备(需确认对应汽车规范后使用);
  • 工业控制器、仪表、测试设备的浪涌保护;
  • PCB 上的局部过电压防护元件。

五、封装与机械信息

SMA(DO‑214AC)封装具有体积小、便于自动化贴装的特点,适合回流焊工艺。封装标识通常不分极性(双向器件),但印字或带状标记用于生产识别。建议在 PCB 布局时保证器件与受保护信号线之间的走线尽可能短,以减少寄生电感导致的钳位效率下降。

六、选型与使用建议

  • 根据实际系统的最大允许工作电压选择Vrwm;SMAJ16CA 的16V Vrwm 适用于 12V 及类似电压等级的系统保护;
  • 注意钳位电压随脉冲电流上升而变化,系统应能容忍在最大雷击电流下的钳位值(约26V);
  • 对持续或重复高能脉冲应采取级联保护或更高额定功率的器件以延长寿命;
  • 焊接时遵循厂商回流温度曲线,避免过高焊接温度或长时间加热;
  • 存储与使用环境避免潮湿、强腐蚀性气体及超过额定温度范围。

七、可靠性与测试注意

器件支持在-65 ℃ ~ +150 ℃范围内工作,适合恶劣环境应用。实际应用中建议在完成 PCB 设计后通过标准脉冲(供应商给定的 8/20 μs 或 10/1000 μs 波形)进行实际浪涌试验验证,确认钳位性能与热稳定性。对有关键安全要求的系统,建议进行全系统级别的浪涌和ESD试验。

八、订购信息与替代方案

完整料号为 SMAJ16CA/TR13(Brightking,卷带包装适用于自动化贴装)。在选型时可参考厂家数据手册以获取详细电气特性曲线、脉冲测试条件及包装信息。需要更高功率或不同 Vrwm 的保护时,可选择同系列的其他型号或同类封装的 TVS 器件。

如需器件的详细曲线、功率脉冲波形及封装尺寸图,我可帮您进一步提供或对接相关数据手册。

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
