SMBJ110CA 产品概述

一、性能亮点

SMBJ110CA(BORN 伯恩半导体)为SMB封装的功率型TVS瞬态抑制器,属于双向(bidirectional)型号,专为电源口及高压瞬态保护设计。具有600W峰值脉冲功率能力与低漏电流特性,能在浪涌事件中快速钳位保护下游器件,适用于工业电源、通信、电力电子与测试设备等场合。

二、主要电气参数

  • 极性:双向
  • 反向截止电压(Vrwm):110 V
  • 击穿电压(VBR):122 V
  • 钳位电压:177 V(峰值脉冲时典型值)
  • 峰值脉冲电流(Ipp):3.4 A
  • 峰值脉冲功率(Ppp):600 W
  • 反向电流(Ir):1 µA(在Vrwm下典型值)
  • 封装:SMB
  • 品牌:BORN(伯恩半导体)

以上参数表明SMBJ110CA在110V级别工况下具有可靠的浪涌承受能力与较低的静态漏电,非常适合对泄漏敏感且需抗浪涌的电源线路保护。

三、典型应用

  • 直流/交流110V电源输入保护
  • 开关电源(SMPS)初级侧浪涌保护
  • 工业控制设备与传感器供电口防护
  • 通信基站、电信设备电源防雷防浪涌
  • 继电器、接触器驱动回路的反向与浪涌吸收

四、使用建议与注意事项

  • 布局:元件应尽量靠近受保护端口并缩短与被保护器件之间的回路长度,以降低环路电感,提高吸收效率。
  • 热管理:峰值能量吸收时会产生热量,建议在PCB上使用适当的铜箔散热并避免连续或频繁的大能量脉冲。
  • 串联保护:在需要更大能量处理能力时,可与熔丝、限流电阻或并联多个TVS器件配合使用。
  • 连续工作:TVS为瞬态保护器件,不宜在其额定截止电压之上长期施加直流电压;长期在Vrwm附近工作会增加漏电与热应力。
  • 极性识别:双向型号能对正负极瞬态均进行钳位,适用于交流或相反极性冲击的场合。

五、封装与可靠性

SMB封装便于表面贴装与波峰/回流焊工艺集成,机械强度与散热能力适中。BORN品牌器件通常经过可靠性筛选与浪涌测试,适合工业级应用。建议在设计时参考厂方的回流焊曲线与储存、防潮规范,以保证焊接质量与长期可靠性。

六、选型与采购建议

选型时确认工作电压与可能的最大浪涌能量,若系统有更高的脉冲电流或更强的雷击需求,应选用额定更高能量或并联方案。采购时可通过型号“SMBJ110CA(BORN)”索取器件样片与完整数据手册,以便获取典型波形、测试条件与封装外形尺寸等详细参数。

Sourcing availability signal

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
