SMBJ85CA/TR13瞬态抑制二极管(TVS)产品概述

一、产品定位与品牌背景

SMBJ85CA/TR13是台湾君耀电子(Brightking)推出的双向贴片瞬态抑制二极管(TVS),核心定位为中小功率电路的过压浪涌防护,尤其适配对体积、宽温可靠性有要求的工业、通信及消费电子场景。君耀作为国内专业防护器件厂商,其TVS产品以高一致性、宽温稳定性著称,SMB系列因贴片封装的易用性,成为市场主流防护方案之一。

二、关键参数与功能解析

SMBJ85CA/TR13的参数设计围绕“快速响应、可靠箝位、低功耗兼容”展开,核心参数及功能如下:

(一)防护核心参数

  • 双向极性:无需区分电路正负端,可同时抑制正负方向的浪涌脉冲(如静电放电、感应雷击、电源瞬变),简化电路设计流程,避免极性接反风险;
  • 电压参数:
    • 反向截止电压(Vrwm=85V):电路正常工作时处于截止态,不影响功耗与信号传输;
    • 击穿电压(Vbr=94.4V):过压触发阈值,避免电压波动误触发;
    • 钳位电压(Vc=137V):峰值脉冲下将电压箝位在安全范围,保护后端敏感器件;
  • 功率电流:峰值脉冲功率(Ppp=600W)、峰值脉冲电流(Ipp=4.4A,8/20μs波形),覆盖常见浪涌场景;
  • 低漏电流:反向漏电流(Ir=1μA),适配低功耗电路(如电池供电设备),避免额外损耗。

(二)环境与封装

  • SMB封装(DO-214AA):体积小巧(4.7×2.6×1.9mm),支持自动贴装,适合高密度PCB布局;
  • 宽温范围:工作温度-65℃~+150℃,覆盖工业级严苛环境(如户外传感器、汽车舱内设备)。

三、典型应用场景

SMBJ85CA/TR13因双向防护、宽温、小体积等特性,广泛应用于以下场景:

  1. 工业控制:PLC电源/IO接口、工业传感器线路防护,应对电机启停浪涌、电磁干扰;
  2. 通信设备:路由器/交换机电源模块、以太网端口ESD防护(符合IEC 61000-4-2标准);
  3. 消费电子:智能插座、移动电源充电端口防护,抑制市电浪涌;
  4. 汽车辅助:车载记录仪、胎压监测电源防护,适配汽车宽温环境。

四、产品优势与选型建议

(一)核心优势

  • 双向防护兼容性:无需极性区分,电路设计更灵活;
  • 宽温可靠性:-65~150℃覆盖严苛环境,避免参数漂移;
  • 低漏低功耗:1μA漏电流不影响电池设备续航;
  • 紧凑易生产:SMB贴片封装适合小型化设计与自动化组装。

(二)选型注意事项

  • 电压匹配:Vrwm需≥电路正常工作电压(预留10%~15%余量);
  • 功率匹配:600W覆盖中小功率浪涌,高功率场景需升级更大功率TVS;
  • 封装适配:SMB为贴片,若需插件可选P6SMB系列。

五、总结

SMBJ85CA/TR13作为君耀SMB系列的经典双向TVS,凭借双向防护、宽温稳定、低漏电流、小体积等核心特性,成为工业、通信、消费电子等领域中小功率电路的可靠浪涌防护方案。其参数设计兼顾“正常电路兼容”与“浪涌防护能力”,可有效抑制静电、雷击、电源瞬变等干扰,保护后端敏感器件,是紧凑设备设计的优选防护器件。

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
