5.0SMDJ16CA/TR13 产品概述

5.0SMDJ16CA/TR13 是 Brightking(台湾君耀)推出的一款双向瞬态电压抑制二极管(TVS),封装为 SMC(DO-214AB)。该器件专为对抗线路上的静电放电(ESD)、雷击和开关瞬变等冲击脉冲而设计,具有高脉冲功率吸收能力与较低的钳位电压,适合用于 12V 类电源线、工业控制总线及其他需要抗浪涌保护的场合。

一、主要电气参数(典型/标称)

  • 极性:双向(可对称处理正负极瞬变)
  • 反向截止电压 Vrwm:16 V(建议稳态工作电压不超过此值)
  • 击穿电压 VBR:17.8 V(典型值)
  • 钳位电压(Ipp 下):26 V(峰值脉冲时的最大钳位电压)
  • 峰值脉冲电流 Ipp:193 A(在制造商指定的脉冲条件下)
  • 峰值脉冲功率 Ppp:5 kW(器件在短时脉冲下的吸收能力;通常以 10/1000 μs 或等效波形测试)
  • 反向漏电流 Ir:50 μA(在 Vrwm 条件下的典型泄漏)
  • 类型:TVS(瞬态抑制器)
  • 封装:SMC(DO-214AB)表面贴装
  • 描述:静电和浪涌保护(TVS/ESD)5.0SMDJ16CA/TR13

二、性能特点

  • 高峰值功率吸收能力:5 kW 的峰值脉冲功率允许器件在短时大能量浪涌(例如雷击或开关瞬变)下工作而不致损坏。
  • 低钳位电压:典型钳位电压 26 V,可在保护受限耐压器件时提供更低的过压幅度。
  • 双向结构:对交流或双向脉冲具有对称保护能力,方便在正负极都可能出现瞬变的系统中使用。
  • 低漏电:在稳态工作电压下漏电小(Ir 约 50 μA),对电源效率和休眠电路影响小。
  • 适应表面贴装工艺:SMC(DO-214AB)封装便于自动化贴装与回流焊工艺,适合批量制造。

三、典型应用场景

  • 汽车电子(如 12V 车载电源总线、车载通讯接口)
  • 工业电源与控制系统(PLC、驱动器、电源模块)
  • 通信设备与基站保护(电源输入、线路接口)
  • 电源适配器与充电器输入侧防护
  • 太阳能逆变器、小型UPS、蓄电池管理系统等需要浪涌保护的场合

四、选型与设计注意事项

  • 稳态电压匹配:选择 Vrwm 等于或略高于系统正常工作电压。例如 12V 系统可选 16V Vrwm 的型号,但当系统存在较大纹波或瞬态电压时需预留裕量。
  • 钳位电压要求:确认被保护器件的绝对耐压,并确保 TVS 的钳位电压在器件承受范围内。钳位电压与脉冲幅度、波形及温度有关,设计时需留安全裕量。
  • 脉冲能量等级:核对实际可能出现的浪涌能量(如雷击、工业浪涌)是否低于 5 kW(制造商测试条件下)以及对应波形的差异。对更高能量事件,可考虑并联或增加串联元件(如保险丝、阻尼器)分担能量。
  • PCB 布局:TVS 应尽量靠近被保护的接口或器件放置,避免长走线;使用宽短的铜箔连接以减小等效电感;必要时在散热区域加设热过孔以增强热量扩散。
  • 温升与热管理:在高频繁浪涌或长期高能耗环境中,需关注器件的温升及热循环寿命,必要时采用外部熔断器或散热措施以延长使用寿命。
  • 包装与装配:型号后缀 TR13 表示以卷带(Tape & Reel)方式供货,适合自动贴装;贴装与回流温度曲线应符合封装工艺规范。

五、可靠性与使用建议

  • 存储与处理:在生产与维护过程中,应采取静电防护措施(佩戴防静电手环与防静电服、使用防静电工作台);避免超过器件额定温度与机械应力。
  • 寿命评估:TVS 在承受规定的冲击能量下能多次工作,但长期频繁遭受高能脉冲会降低其性能。关键系统建议配合熔断保护和冗余设计。
  • 测试与验证:在设计验证阶段,应使用代表性脉冲波形(例如 10/1000 μs、8/20 μs 等)进行实测,确认钳位、电流与温升满足系统需求。

5.0SMDJ16CA/TR13 提供了一种可靠、易于集成的瞬态浪涌保护方案,特别适合需要在有限空间内实现高能量吸收与低钳位保护的 12V 级电源与信号线场合。选择与实际应用条件(工作电压、预期浪涌能量、布局约束)匹配的 TVS 器件,可以显著提高系统的抗干扰与抗损坏能力。

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.
