SMCJ150A/TR13 产品概述

一、产品概述

SMCJ150A/TR13 是 Brightking(台湾君耀)推出的一款高能量瞬态电压抑制器(TVS),采用低轮廓表面贴装封装 SMC(DO-214AB),为需要高功率冲击保护且占板面积受限的电路提供可靠防护。该器件为单向结构,适用于直流或单向脉冲环境下对电源线、I/O 接口及工业电路的浪涌与瞬态过电压保护。

二、主要技术参数

  • 极性:单向
  • 反向稳态电压 Vrwm:150 V
  • 击穿电压 VBR(I_BR 测试点):167 V
  • 钳位电压(在峰值脉冲电流 Ipp 条件下):243 V
  • 峰值脉冲电流 Ipp:6.2 A
  • 峰值脉冲功率 Ppp:1.5 kW(参考标准冲击条件)
  • 漏电流 Ir:1 μA(在 Vrwm 条件下典型)
  • 工作温度范围:-65 °C ~ +150 °C
  • 类型:瞬态电压抑制器(TVS),单向
  • 封装:SMC(DO-214AB),表面贴装
  • 品牌:Brightking(台湾君耀)

三、关键特性

  • 表面贴装(SMC)封装,低轮廓设计,有利于电路板空间优化与自动化贴装。
  • 低电感结构,适合对快速瞬态响应要求高的系统。
  • 玻璃钝化结工艺,增强结面稳定性与长期可靠性。
  • 内置应力消除结构,提高焊接和热循环后的机械与电气稳定性。
  • 低漏电流,适合对静态功耗敏感的电源轨与信号线保护。
  • 优异的钳位能力,可在规定冲击能量下将过电压控制在安全范围,保护后级器件。

四、典型应用场景

  • AC/DC 电源输入及整流后直流母线的浪涌保护。
  • I/O 接口、通讯端口(如工业以太网、现场总线)以及电源分配线的瞬态抑制。
  • 电机驱动、逆变器及太阳能并网设备中对开关瞬态的抑制。
  • 工业、汽车电子(非安全关键高压应用)、测量仪器等需要高功率浪涌承受能力的场合。

五、使用与安装建议

  • 焊接与回流:推荐采用 SMT 自动贴装与回流焊工艺,遵循器件厂或 JEDEC 的回流温度曲线,避免过长高温暴露以保证玻璃钝化和封装完整性。
  • 热管理:虽然 SMC 封装具备较高功率承受能力,但在重复或高能脉冲环境下应保证良好散热路径,建议在器件底部与附近铺设铜焊盘并与大面积接地铜箔连接,以便散热和降低焊点电阻。
  • 布局:将 TVS 尽可能靠近需保护的受害端(如插座、接线端或信号入口),并缩短引线长度以降低串联电感,提高保护响应速度。
  • 焊盘设计:按厂商推荐的 PCB 焊盘尺寸设计,确保机械强度与热传导效果,便于波峰/回流焊可靠性。
  • 储存与处理:存放在干燥环境,贴片卷带(TR)包装便于 SMT 产线直接使用。

六、选型与注意事项

  • 工作电压匹配:Vrwm=150V 表示该器件适用于最高工作电压接近或低于 150V 的直流/单极性线路;在选择时应留有足够裕量,避免常态下长时间接近 Vrwm。
  • 单向 vs 双向:本型号为单向类型,适合直流或单极脉冲环境;若用于交流或双向浪涌,需选择对应的双向 TVS。
  • 钳位能力与后级器件耐压:钳位电压 243V(在 Ipp 6.2A 条件下)是设计时必须对照后级器件耐压能力的关键指标。
  • 多次冲击与能量预算:若应用场合存在频繁或高能量冲击,应评估器件的重复承受能力及必要的外部限流(熔断器、电感)方案。

七、封装与订购信息

  • 封装形式:SMC(DO-214AB),适合自动化 SMT 生产线。
  • 包装形式:TR(卷带),便于料带投料与高速贴装。
  • 型号示例:SMCJ150A/TR13(请与供应商确认完整料号、批次与可用库存)。

八、可靠性与环境适应

SMCJ150A/TR13 设计用于工业级温度范围(-65 °C 至 +150 °C),适应环境温度波动和电气冲击场景。基于玻璃钝化与应力消除结构,其长期稳定性与抗热循环能力良好。为确保系统可靠性,建议在最终设计中进行实际浪涌试验验证并与系统保护策略(限流、熔断、冗余)配合使用。

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
