SMBJ60CA TVS二极管产品概述

一、产品基本定位

SMBJ60CA是晶导微电子推出的瞬态抑制二极管(TVS),属于SMBJ系列表面贴装器件,采用SMB(DO-214AA)封装。核心功能是针对电子电路中的瞬态过压(如浪涌、静电放电等)提供快速、可靠的防护,避免后端敏感元器件(如MCU、传感器、通信芯片等)因过压损坏,精准适配60V及以下中低压电路系统的防护需求。

二、核心电气参数深度解析

SMBJ60CA的电气参数精准匹配工业/消费电子场景,关键参数的实际意义如下:

  1. 反向截止电压(Vrwm=60V):正常工作时允许承受的最大反向直流电压,明确适配24V/48V工业电源、通信接口等60V以内的电路系统;
  2. 钳位电压(96.8V):浪涌触发时的电压钳位上限,可确保后端器件(如常见MCU的过压阈值多在100V以内)不被损坏;
  3. 峰值脉冲电流(Ipp=6.2A@10/1000μs):以10/1000μs(前沿10μs、半峰值1000μs)脉冲测试下的最大耐受电流,覆盖雷击、电源开关浪涌等常见冲击;
  4. 峰值脉冲功率(Ppp=600W):对应脉冲波形的功率耐受能力,直接反映浪涌防护强度,满足大多数场景的冲击需求;
  5. 反向漏电流(Ir=1μA):正常工作时漏电流极小,不影响电路静态功耗与信号完整性;
  6. 结电容(Cj=390pF):适配10MHz以下中低频电路(如RS485、电源模块),无明显信号衰减;
  7. 宽温范围(-65℃~+150℃):覆盖工业级、部分汽车场景及极端环境,如户外设备、高温车间等。

三、封装与品牌背景

1. 封装特性

SMB(DO-214AA)为表面贴装式封装,尺寸小巧(约2.5mm×4.5mm×1.5mm),适配自动化贴片生产,安装效率高;封装结构兼顾散热与防护,可降低工作热应力,延长器件寿命。

2. 品牌优势

晶导微电子是国内功率半导体核心厂商,专注TVS、MOSFET等器件研发,产品通过AEC-Q101可靠性认证,品质稳定,广泛应用于工业控制、汽车电子、通信设备等领域。

四、典型应用场景

SMBJ60CA的参数特性使其适配以下场景:

  1. 工业控制电源:PLC、变频器的24V/48V端口,应对开关浪涌、雷击感应过压;
  2. 通信接口:RS485、以太网等中速接口,抑制ESD与信号浪涌;
  3. 汽车电子:车载传感器(温度/压力)、低电压控制模块的过压防护(宽温适配车载环境);
  4. 消费电子:智能家居、小型家电的电源端口,保护MCU与电源芯片;
  5. 仪器仪表:示波器、传感器输入输出端口,避免测试瞬态过压损坏。

五、性能优势总结

  1. 宽温可靠:-65℃~+150℃适配极端环境;
  2. 高效防护:ns级快速响应+精准钳位,抑制浪涌效果显著;
  3. 低功耗:1μA漏电流不影响电路静态功耗;
  4. 生产适配:SMB封装适合自动化生产,节省PCB空间;
  5. 高性价比:成熟工艺兼顾性能与成本,适配批量应用。

该器件凭借稳定的防护性能与宽适配性,成为中低压电路过压防护的主流选择之一。

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
