SMBJ220CA/TR13 TVS二极管产品概述

一、产品定位与核心属性

SMBJ220CA/TR13是台湾君耀(Brightking) 推出的一款双向瞬态抑制二极管(TVS),属于过压保护器件范畴,专为电子电路中的瞬态浪涌电压抑制设计,可有效防护正负双向的瞬态过压冲击,避免后端敏感元器件(如IC、传感器、通信模块等)因过压损坏,是工业、汽车、通信等领域的高可靠性防护选择。

二、关键性能参数解析

该器件的核心参数明确了其防护能力与工作边界,具体如下:

  • 反向截止电压(Vrwm):220V:正常工作状态下,器件反向截止时可承受的最大直流/交流电压,确保电路无额外漏电流干扰,适配220V等级的电源或信号线路;
  • 钳位电压(Vc):356V:在峰值脉冲电流(1.7A)作用下,器件两端被钳位的最大电压值,是判断防护效果的核心指标——可将过压限制在后端器件的耐受阈值内,避免击穿损坏;
  • 峰值脉冲电流(Ipp):1.7A、峰值脉冲功率(Ppp):600W:器件单次可承受的最大脉冲电流与功率,能应对典型浪涌冲击(如雷击、开关浪涌、静电放电等);
  • 击穿电压(Vbr):246V:反向电压达到该值时,器件开始进入击穿导通状态,是过压防护的启动阈值,与Vrwm(220V)形成合理防护裕量;
  • 反向漏电流(Ir):1μA:低漏电流设计,确保器件在正常工作电压下(≤220V)几乎不消耗额外功率,不影响电路效率;
  • 工作温度范围:-65℃~+150℃:宽温特性使其可适应工业级(低温存储、高温工作)、汽车级(发动机舱高温、低温环境)等严苛场景。

三、封装形式与应用场景

  • 封装:SMB(DO-214AA):表面贴装式封装,体积小巧(尺寸约3.8×1.7×1.2mm),适合高密度PCB布局,兼容自动化贴装工艺,广泛用于小型化电子设备;
  • 典型应用场景:
    1. 工业控制:PLC、传感器模块的电源与信号端口防护;
    2. 汽车电子:车载充电器、CAN总线、胎压传感器电路的过压保护(宽温适配汽车级环境);
    3. 通信设备:路由器、交换机的以太网端口、电源输入的浪涌抑制;
    4. 消费电子:智能家居设备、电源适配器的过压防护;
    5. 新能源:充电桩、光伏逆变器辅助电路的浪涌防护。

四、性能优势与可靠性特点

  1. 双向防护能力:可同时抑制正负瞬态浪涌,无需额外配置单向器件,简化电路设计;
  2. 快速响应特性:TVS二极管典型响应时间为纳秒(ns)级,能在浪涌到达后端器件前迅速导通钳位;
  3. 低功耗与高稳定性:1μA低漏电流确保正常工作无额外损耗,击穿电压一致性好,防护可靠性高;
  4. 宽温适配性:-65℃~+150℃温度范围,满足工业、汽车等领域的严苛环境要求;
  5. 高脉冲耐受能力:600W峰值脉冲功率可应对多次浪涌冲击,延长设备使用寿命。

五、典型应用电路说明

SMBJ220CA/TR13通常以并联方式接入被保护电路:

  • 电源端口防护:并联在电源输入端(Vcc与GND之间),浪涌时击穿导通,将电压钳位在356V以下,保护后端IC;
  • 信号线路防护:对于RS485、CAN等差分线路,并联在信号线与GND之间,抑制共模浪涌;
  • 负载端防护:并联在敏感负载(如传感器、通信模块)两端,直接抑制负载端过压冲击。

该器件凭借双向防护、宽温特性与高可靠性,成为多领域过压保护的优选器件,可有效提升电子设备的抗干扰能力与使用寿命。

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
