SMCJ75CA/TR13 产品概述

一、产品简介

SMCJ75CA/TR13 是 Brightking(台湾君耀)出品的一款双向瞬态电压抑制器(TVS),采用 SMC(DO-214AB)封装。该器件针对瞬时过电压、雷击和开关瞬变等脉冲能量事件提供双向夹断保护,适用于工业电源线、直流母线、逆变器接口及通讯/控制系统的浪涌保护需求。TR13 后缀通常表示卷带(Tape & Reel)自动化贴装包装,便于SMT生产线使用。

二、主要电气参数

  • 极性:双向(双向对称夹位,正负瞬态均可吸收)
  • 反向截止电压 Vrwm:75 V(器件在正常工作状态下最大持续工作电压)
  • 击穿电压 Vbr(典型):83.3 V(器件进入雪崩导通的电压区间)
  • 钳位电压 Vc:121 V(在指定脉冲条件下的最大夹位电压)
  • 峰值脉冲电流 Ipp:12.4 A(在规定脉冲条件下能承受的瞬态电流峰值)
  • 峰值脉冲功率 Ppp:1.5 kW(器件在短时间脉冲下能吸收的最大能量能力)
  • 反向电流 Ir:1 μA(在 Vrwm 条件下的泄漏电流,表示静态漏电很小)

以上参数体现了该型号在高能量浪涌事件下的吸能能力与钳位效能,适合中高电压等级的防护场景。

三、特点与应用

  • 双向保护:无需外加极性判断,适合交流或可反向电压环境。
  • 高峰值功耗吸收:1.5 kW 脉冲能量能力配合 SMC 封装,适合工业级浪涌与雷击脉冲防护。
  • 低静态泄漏:在额定工作电压下 Ir 约 1 μA,利于对敏感电路的长期保护而不影响正常运行。
  • 典型应用:光伏逆变器侧浪涌保护、48V 通信电源防护、电机驱动接口、汽车车载附件(非关键安全回路需确认)、配电柜与工业控制柜的输入/输出保护等。

四、封装与热特性

SMC(DO-214AB)封装提供良好的热扩散路径与机械强度,适合波峰或回流焊工艺。实际使用时应关注功率耗散与热阻:在连续或重复脉冲条件下,需配合良好散热的PCB布局(加大焊盘铜面积、增加热穿孔)以防止局部过热与器件退化。

五、PCB 布局与安装建议

  • 走线最短:将 TVS 靠近被保护引脚或接口,以缩短串联电感和寄生电阻,提升响应速度。
  • 加大铜箔:器件两侧大面积铜箔和多通孔散热,利于脉冲能量分散。
  • 回流焊规范:按照元件与PCB工艺规定的回流曲线焊接,避免过高温度和长时间热暴露。
  • 旁路/滤波配合:在需要时与滤波电容、浪涌抑制器件组合使用,以达到更好的干扰抑制效果。

六、选型与注意事项

  • 确认电路最大工作电压:Vrwm 75V 适用于高于常规 48V 但低于其击穿电压的系统,选用前务必确认系统最大持续电压。
  • 关注钳位电压:钳位 121V 在某些敏感元件前可能仍然较高,需评估被保护器件能否承受该峰值。
  • 脉冲能量匹配:1.5 kW 的峰值功率适合短时高能脉冲,长期或重复高能冲击需考虑并联/冗余设计或更高能量级别器件。
  • 采购信息:TR13 表示卷带装,便于SMT自动贴装;大批量采购建议向供应商确认批次、出厂测试条件及质量保证。

如需更详细的参数曲线(V-I 特性、钳位随脉冲幅度变化、热阻 RθJA 等)或样片测试计划,我可以根据具体测试条件帮您制定验证方案。

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
