SMBJ58CA 双向瞬态抑制二极管(TVS)产品概述

SMBJ58CA是瑞隆源(RUILON)推出的一款小型化表面贴装双向TVS管,专为电子电路中的瞬态过压防护设计,凭借紧凑的SMB封装、宽温度范围耐受及稳定的浪涌防护能力,广泛适配消费电子、工业控制等多领域的高密度PCB布局需求。

一、产品核心定位与类别属性

SMBJ58CA属于瞬态抑制二极管(TVS) 范畴,核心功能是快速响应电路中的浪涌脉冲(如静电放电、雷击感应、开关瞬态等),将过电压钳位在安全范围内,避免后级敏感器件(如IC、传感器、接口电路)被击穿损坏。其双向极性设计无需区分正负极,简化了电路设计与焊接工艺,适配各类双向信号链路的防护场景。

二、关键电气参数与防护性能解析

SMBJ58CA的电气参数经过严格测试,核心指标直接决定其防护能力与适用场景:

1. 电压类参数(防护核心)

  • 反向截止电压(Vrwm=58V):正常工作状态下,器件反向漏电流极小(≤1μA)的电压上限,即电路稳态电压不超过58V时,SMBJ58CA以“低损耗”模式存在,不影响电路正常功能;
  • 击穿电压(Vbr=74.1V):过压触发时的典型导通电压,当电路电压超过该值时,器件快速从高阻态转为低阻态,启动防护;
  • 钳位电压(Vc=93.6V):10/1000μs标准浪涌脉冲下的最高电压,是防护的“最终阈值”——即使出现强浪涌,电压也被稳定钳位在93.6V以下,保护后级器件(如耐压100V以下的IC、接口芯片)安全。

2. 浪涌耐受能力

  • 峰值脉冲功率(Ppp=600W):针对10/1000μs波形(行业标准浪涌测试波形)的最大耐受功率,可有效应对常见的开关瞬态、雷击感应浪涌;
  • 峰值脉冲电流(Ipp=6.4A):对应600W功率下的脉冲电流,反映器件快速泄放浪涌能量的能力。

3. 低损耗特性

反向漏电流(Ir=1μA):在Vrwm=58V下的漏电流仅1μA,远低于多数同类器件,长期工作时几乎不产生额外功耗,避免影响电路效率与稳定性。

三、封装与物理特性

SMBJ58CA采用SMB封装(DO-214AA标准),具备以下优势:

  • 小型化设计:封装尺寸约2.3mm×4.0mm×1.5mm,适配高密度PCB布局(如手机、平板的接口电路、小型工业模块);
  • 表面贴装兼容:支持自动化贴装(SMT),焊接可靠性高,符合电子制造行业的量产需求;
  • 机械强度:封装结构紧凑,抗振动、抗冲击能力满足工业级与消费电子的环境要求。

四、适用场景与应用优势

SMBJ58CA的参数特性使其适配多类场景:

  1. 消费电子接口防护:手机USB接口、平板HDMI接口、耳机接口的静电与浪涌防护(空间紧凑+双向防护);
  2. 工业控制电路:PLC输入输出接口、传感器信号链路的过压防护(-55℃~+150℃宽温度范围);
  3. 小型电子模块:物联网节点、智能穿戴设备的电源与信号防护(低漏电流+小型封装)。

核心应用优势:

  • 双向防护无需极性区分,简化设计;
  • 低漏电流不影响电路正常工作;
  • 600W浪涌功率耐受覆盖多数常见浪涌场景;
  • 宽温度范围适配极端环境。

五、可靠性与环境适应性

SMBJ58CA的可靠性指标满足行业标准:

  • 工作温度范围:-55℃+150℃,覆盖工业级(-40℃+85℃)与高温场景(如车载辅助电路);
  • 浪涌测试合规:通过10/1000μs波形的600W脉冲测试,符合IEC 61000-4-5浪涌抗扰度要求;
  • 长期稳定性:低漏电流设计避免器件老化过快,延长电路使用寿命。

六、品牌与合规性

SMBJ58CA由国内知名过压保护器件厂商瑞隆源(RUILON) 生产,产品符合:

  • 封装标准:DO-214AA国际标准;
  • 电气安全:符合RoHS无铅环保要求;
  • 质量体系:通过ISO 9001质量管理体系认证,可靠性有保障。

总结:SMBJ58CA作为一款高性价比的双向TVS管,以紧凑封装、稳定防护、宽温耐受为核心优势,是消费电子、工业控制等领域电路过压防护的可靠选择。

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.
