3.0SMBJ58CA瞬态抑制二极管(TVS)产品概述

一、产品基本定位

3.0SMBJ58CA是伯恩半导体(BORN) 推出的单通道瞬态抑制二极管(TVS),采用DO-214AA(SMC)表面贴装封装,专为低压电路的瞬态过压保护设计,可有效抑制雷电、静电放电(ESD)、开关浪涌等瞬态脉冲对敏感电子元件的损坏,是工业控制、通信设备、消费电子等领域的常用保护器件。

二、核心电气参数深度解析

该产品的电气参数直接决定其保护能力,关键参数及实际意义如下:

1. 反向截止电压(Vrwm)

额定值为58V,指TVS在正常工作状态下(无瞬态脉冲时),可长期承受的最大反向电压而不发生击穿。电路设计时需确保电源或信号的正常工作电压不超过58V,避免误触发保护。

2. 击穿电压(Vbr)

额定值为60V,是TVS反向击穿的电压阈值(略高于Vrwm)。当电路出现瞬态过压且电压超过60V时,TVS快速导通,将过压能量泄放至地,保护后端电路免受过压冲击。

3. 钳位电压(Vc)

额定值为85V,是TVS导通后能将电路电压钳位的最高值(在峰值脉冲电流下)。该参数直接反映保护效果:85V与58V的差值(27V)处于合理范围,既保证快速响应,又避免钳位电压过高对后端元件造成二次损伤。

4. 峰值脉冲电流(Ipp)

额定值为500A@8/20μs,其中“8/20μs”是国际标准浪涌波形(前沿8μs、半峰值持续20μs)。该参数表明产品可承受最大500A的峰值浪涌电流,能有效应对中等强度的雷电或开关浪涌。

5. 峰值脉冲功率(Ppp)

额定值为3kW@10/1000μs,“10/1000μs”是长脉冲浪涌波形(前沿10μs、半峰值持续1000μs)。3kW的峰值功率覆盖了多数低压电路的浪涌能量需求,可保护电源、接口等关键部位。

6. 反向漏电流(Ir)

额定值为1μA(在Vrwm下),是TVS反向截止时的漏电流。极低的漏电流确保产品在正常工作时功耗极低,适合对功耗敏感的电子设备(如便携式仪器、低功耗通信模块)。

三、封装与物理特性

3.0SMBJ58CA采用DO-214AA封装(俗称SMC封装),具有以下优势:

  • 小型化:尺寸约为2.54mm×1.52mm×1.02mm,适合高密度PCB设计,可集成于紧凑的电子设备中;
  • 表面贴装:支持自动化贴装,生产效率高,降低人工成本;
  • 散热性:封装结构利于热量快速散发,可承受多次脉冲冲击而不失效。

四、典型应用场景

结合产品参数,3.0SMBJ58CA适用于以下场景:

  1. 通信设备:路由器、交换机、光模块的电源接口及信号接口浪涌保护;
  2. 工业控制:PLC、传感器、伺服驱动器的低压控制电路保护;
  3. 消费电子:手机充电口、电视HDMI接口、智能家居设备的过压防护;
  4. 汽车电子:12V低压辅助电路(如车载USB、传感器)的瞬态保护;
  5. 电源模块:低压直流电源(如12V、24V系统)的浪涌抑制。

五、品牌与可靠性优势

伯恩半导体(BORN)是国内专注于保护器件的知名厂商,3.0SMBJ58CA具备以下可靠性优势:

  • 标准符合性:符合IEC 61000-4-5(浪涌抗扰度)、IEC 61000-4-2(ESD抗扰度)等国际标准;
  • 一致性好:击穿电压、钳位电压的偏差控制在±5%以内,批量应用稳定性高;
  • 长寿命:可承受数千次脉冲冲击而性能无明显衰减,适合长期工作的工业/通信设备。

六、选型与应用注意事项

  1. 电压匹配:电路正常工作电压需≤58V(Vrwm),避免TVS误导通;
  2. 脉冲能量匹配:需确认电路中可能出现的浪涌能量不超过3kW(Ppp)及500A(Ipp);
  3. 极性确认:单通道TVS需注意极性(反向接保护电路),若需双向保护可选择对应双向型号;
  4. 并联使用:若单颗产品无法满足脉冲能量需求,可采用多颗并联(需确保参数一致)。

该产品凭借平衡的保护性能、小型化封装及高可靠性,成为低压电路瞬态保护的高性价比选择。

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.
