SMBJ100CA 产品概述 — 晶导微电子

一、主要规格概述

SMBJ100CA 为晶导微电子推出的一款功率型瞬态电压抑制器(TVS 二极管),用于抑制雷击、开关转换及电磁干扰引起的瞬态过压。关键电气参数如下:

  • 钳位电压(VC):162 V(峰值脉冲条件下)
  • 击穿电压(Vbr):123 V
  • 反向截止电压 Vrwm:100 V
  • 峰值脉冲功率 Ppp:600 W(10/1000 μs 波形)
  • 峰值脉冲电流 Ipp:3.7 A(10/1000 μs)
  • 结电容 Cj:390 pF(典型)
  • 反向漏电流 Ir:1 μA(在 Vrwm 条件)
  • 工作温度范围:-65 ℃ 至 +150 ℃
  • 封装:SMB(表面贴装)

二、主要特性

  • 高能量吸收能力:在 10/1000 μs 脉冲下可承受 600 W 峰值功率,适合线路级浪涌保护。
  • 低泄漏、明确钳位:在 Vrwm 下极低反向电流(1 μA),在冲击时钳位至 162 V,有效保护后端器件。
  • 宽温度适应性:-65 ℃ 至 +150 ℃ 满足汽车、工业等严苛环境需求。
  • 适合高速接口:结电容 390 pF,适用于对电容敏感度中等的信号或电源线路防护。

三、典型应用场景

  • 电源总线与配电箱的浪涌保护
  • 工业控制设备与变频器的输入保护
  • 汽车电子(车载电源、传感器接口等)的瞬态抑制
  • 通信设备、基站、电表及楼宇自动化系统的接口保护
  • 浪涌防护模块与SPD(Surge Protective Device)单元

四、封装与机械注意

  • SMB 封装,适合自动贴装与回流焊工艺。
  • 封装上通常带有极性或带状标识,请根据出货样品或器件标识确认安装方向(若为单向 TVS,阴极一侧通常有标记)。
  • 推荐在 PCB 上为 TVS 预留足够的焊盘和散热面积,以帮助热量扩散。

五、使用与布局建议

  • 将 SMBJ100CA 尽量靠近受保护的电源/信号端口铺设,连线尽可能短且宽,减少寄生电感。
  • 对于高能量冲击场景,建议在附近增加熔断器或限流元件以实现多级保护。
  • 在高频或对电容敏感的信号线上,确认 390 pF 的结电容对信号完整性的影响,如有需要选择低电容型 TVS 或采取差分/屏蔽措施。

六、可靠性与环境适应

  • 器件设计用于宽温区间及高冲击工作条件,适合长寿命工业与汽车应用。
  • 实际可靠性与寿命还依赖于布局散热、最大承受脉冲次数与外部限流措施,建议在应用中进行实际浪涌测试与老化验证。

七、采购与替代建议

  • 型号:SMBJ100CA DZ,品牌:晶导微电子,封装 SMB。订购时请确认完整型号与厂家出货条码以避免混淆。
  • 若需更低钳位或更高能量吸收,可考虑更大功率封装或并联多只 TVS;若需更低结电容以保护高速信号,建议选用专用低容型 TVS 器件。

本器件面向需要在 100 V 等级工作电压下提供强鲁棒性瞬态保护的场合,结合合适的 PCB 布局和配套保护措施,可显著提高系统对雷击和开关冲击的抗扰度。若需进一步的电气曲线、封装尺寸或典型波形测试数据,可向晶导微电子索取详细数据手册与测试报告。

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
