RUILON SMBJ16A 瞬态抑制二极管(TVS)产品概述

一、产品基本定位与核心属性

SMBJ16A是RUILON(瑞隆源)推出的单向瞬态抑制二极管(TVS),属于过压防护核心器件,通过反向击穿机制快速响应静电放电(ESD)、电快速瞬变脉冲群(EFT)等瞬态干扰,将电压钳位在安全范围内,避免后端敏感元件(如IC、传感器)损坏。其采用SMB(DO-214AA)表面贴装封装,体积紧凑,适配小型化、高密度电路设计需求。

二、核心电气参数深度解析

SMBJ16A的参数针对中低压系统防护优化,关键参数及实际意义如下:

1. 直流工作与击穿特性

  • 反向截止电压(Vrwm):16V
    正常工作时反向可承受的最大直流电压,无明显漏电流。适配12V、15V电源系统(如消费电子主板、工业控制电源),避免器件误导通。
  • 击穿电压(Vbr):20.5V(典型值)
    反向击穿起始电压,比Vrwm高28%,确保正常电压下稳定截止,瞬态过压触发时快速响应。
  • 反向漏电流(Ir):1μA(@Vrwm)
    漏电流极小,不影响电路功耗或信号完整性,适合低功耗设备(如便携式电子)。

2. 瞬态防护性能

  • 钳位电压(Vc):26V
    脉冲电流下的最大电压,比击穿电压高27%。若后端IC最大耐压为20V,26V钳位电压可有效抑制过压(瞬态脉冲持续时间极短,不超IC瞬态极限)。
  • 峰值脉冲功率(Ppp):600W@10/1000μs
    对应国际标准波形(上升10μs、半峰值1000μs)的最大功率,换算峰值电流Ipp≈23.1A,可应对中等强度干扰(如电源浪涌、接口静电)。
  • 工作温度:-55℃~+150℃
    宽温覆盖工业级(-40℃~+85℃)、极端环境,高低温下性能稳定无漂移。

三、防护性能与行业标准符合性

SMBJ16A通过两项核心EMC标准,适配多场景防护:

  • IEC 61000-4-2(ESD):承受接触放电≥8kV、空气放电≥15kV,防护人体静电对USB、HDMI等接口的冲击;
  • IEC 61000-4-4(EFT):抑制MHz级快速脉冲干扰,保护工业PLC、通信设备端口。

器件响应时间达ns级,可在干扰到达后端元件前完成钳位,避免不可逆损坏。

四、封装与典型应用场景

1. 封装特点

SMB(DO-214AA)为表面贴装型,尺寸约2.3mm×3.8mm×1.2mm,重量≈0.05g,适合自动化贴装,适配高密度PCB(如智能手机主板、小型工业模块)。

2. 典型应用

  • 消费电子:手机、平板的USB接口、充电端口防护;
  • 工业控制:PLC输入输出口、传感器模块、电机驱动电路防护;
  • 通信设备:路由器、交换机的以太网端口、电源模块防护;
  • 车载电子:12V车载系统(如仪表盘、辅助驾驶传感器)的瞬态防护(需结合整车EMC验证)。

五、品牌与可靠性说明

RUILON是国内专注过压防护的半导体厂商,SMBJ16A通过ISO 9001认证,批次一致性好,参数偏差小。其宽温性能、低漏电流及高脉冲功率设计,可靠性达行业水平,可替代进口同类器件(如Littelfuse SMBJ16A),性价比优势明显。

该器件以紧凑封装、宽温特性及多标准兼容,成为中低压系统瞬态防护的高性价比选择。

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
