SMCJ110A 产品概述

一、产品简介

SMCJ110A 是 BORN(伯恩半导体)推出的一款单向瞬态电压抑制器(TVS),专为保护中低压直流/信号线路免受瞬态浪涌和浪涌过电压冲击而设计。器件采用玻璃钝化芯片与环氧树脂封装,SMC(DO-214AB)封装形式兼顾功率耗散能力与实装可靠性,适用于电信、计算机及工业接口等场景。

二、主要电气参数

  • 极性:单向(Unidirectional)
  • 反向截止电压 Vrwm:110 V
  • 击穿电压 VBR:122 V(典型,按厂方测试条件)
  • 钳位电压 Vc:177 V(在峰值脉冲电流 Ipp 条件下测得)
  • 峰值脉冲电流 Ipp:8.5 A
  • 峰值脉冲功率 Ppp:1.5 kW
  • 反向电流 Ir:1 μA(在 Vrwm 下)
  • 类型:TVS,封装:SMC (DO-214AB)

这些参数表明 SMCJ110A 在 110 V 工况下具有低漏电流和良好的钳位性能,能够在遭遇短时高能量脉冲时有效限制电压上升,保护后端电路。

三、主要特性

  • 出色的钳位能力:在指定峰值脉冲电流下钳位电压 177 V,能将浪涌能量限制在可接受范围。
  • 低漏电流:在正常工作电压下反向电流仅约 1 μA,有利于降低待机功耗与误触发概率。
  • 低电容:适合保护高速信号线或对电容敏感的接口。
  • 高浪涌能力:1.5 kW 峰值脉冲功率与 8.5 A 峰值脉冲电流表明对短时大能量冲击具备较强承受力。
  • 制造工艺:玻璃钝化芯片提高长期可靠性,环氧封装利于批量装配。

四、典型应用

  • 电信设备的线缆防护与接口保护(如基站、光纤收发端口前端)。
  • 计算机及外设电源总线、接口(USB、串口等)协同保护方案。
  • 工业控制器、测试设备等含有 110 V 级别直流侧或信号线的浪涌防护。
  • 任何需要在受限空间内提供高能量浪涌防护的场合。

五、设计与使用建议

  • 尽量将 TVS 器件靠近被保护端口布置,走线尽量短且宽,减小寄生电感以提升钳位效果。
  • 与熔断器、限流电阻或电感配合使用,实现级联保护与能量分流,避免单元长期承受重复大能量冲击。
  • 注意热量管理:SMC 封装具备一定散热能力,但在高频繁冲击或高环境温度下需考虑散热路径与器件余热。
  • 在高频信号路径使用前确认电容影响,尽管该型号标称电容低,但对极高速链路仍需评估时钟完整性。
  • 钳位电压为在峰值脉冲电流下测得的典型值,实际电路中会受 PCB 布局、寄生参数和波形影响,应在系统级进行验证。

六、可靠性与注意事项

  • 玻璃钝化芯片与环氧封装提高抗湿热与热循环性能,但仍需遵守制造商关于回流焊温度曲线与存储环境的规定。
  • 对于连续或重复的大能量冲击,应对器件进行寿命评估与必要的冗余设计。
  • 如需并联或串联多个 TVS 单元以获得更高功率或更低钳位,请咨询厂方技术支持以确认匹配与失配风险。

七、结论

SMCJ110A(BORN)是一款面向 110 V 工作点的高可靠性单向 TVS,凭借低漏电流、低电容、优异钳位和较高瞬态能量承受能力,适合电信与计算机等对瞬态保护有较高要求的场合。在实际设计中通过合理的布局、能量协调与热管理,可以充分发挥其保护性能,提升系统的抗浪涌和抗短时击穿能力。若需详细数据图表或参考电路,请参考厂方 Datasheet 或联系供应商获取完整技术资料。

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
