Brightking SMCJ28CA-AT/TR13 汽车级TVS二极管产品概述

一、产品核心定位与基本属性

SMCJ28CA-AT/TR13是台湾君耀(Brightking)针对车载电子系统过压防护设计的双向瞬态抑制二极管(TVS),属于汽车级器件。产品采用SMC(DO-214AB)表面贴装封装,体积紧凑,适配车载电路高密度布局需求,是车载敏感电子元件(如MCU、传感器)的可靠防护器件。

二、关键电性能参数解析

该型号TVS的参数围绕“瞬态冲击耐受”与“正常工作稳定性”优化,核心参数意义如下:

  1. 反向截止电压(Vrwm=28V):器件正常工作时可承受的最大反向直流电压,若系统工作电压(如车载12V电源)长期低于28V,可确保无反向导通风险。
  2. 击穿电压(Vbr=31.1V):反向电压超过此值时,器件从高阻态快速切换为低阻态,启动过压保护,避免后端电路因电压骤升受损。
  3. 钳位电压(Vc=45.4V):脉冲电流作用下的最高电压上限,直接决定后端敏感元件的安全阈值——45.4V的钳位值可有效抑制瞬态尖峰(如静电放电、负载突变)对芯片的冲击。
  4. 峰值脉冲能力(Ipp=33.1A/Ppp=1.5kW):可耐受1.5kW的瞬态脉冲功率,覆盖车载系统常见的ESD、电磁干扰等冲击场景。
  5. 反向漏电流(Ir=1μA):正常工作时漏电流极低,减少自身功耗,不影响系统电源效率。

三、封装与物理特性

产品采用SMC(DO-214AB)表面贴装封装,具备以下优势:

  • 体积紧凑:典型尺寸约2.0mm×3.0mm×1.1mm,适配车载导航、行车记录仪等小型化电路布局;
  • 贴装兼容性:支持自动化SMT生产,满足汽车电子批量制造需求;
  • 汽车级可靠性:封装材料可承受-55℃~+150℃宽温范围,抗振动、耐湿热性能符合AEC-Q101汽车级标准(君耀汽车级器件普遍通过该认证)。

四、品牌与可靠性优势

Brightking(君耀)作为半导体行业老牌厂商,其汽车级TVS具备以下可靠性保障:

  • 严苛测试:每批次经高低温循环、湿度老化、振动冲击等多重测试,确保车载复杂环境下长期稳定;
  • 一致性强:先进生产工艺使参数离散性小,不同批次性能一致,降低系统设计风险;
  • 双向保护:无需搭配单向器件即可抑制正、负瞬态脉冲(如车载CAN总线正负干扰),简化电路设计。

五、典型应用场景

该型号TVS因汽车级资质与双向特性,广泛应用于:

  1. 车载通讯:CAN/LIN总线接口、蓝牙/WiFi模块,抑制总线瞬态干扰;
  2. 车载传感器:胎压监测(TPMS)、摄像头、雷达的信号/电源端口,保护敏感芯片;
  3. 车载显示控制:中控屏、仪表盘、行车记录仪的电源/信号线路,避免瞬态电压损坏驱动单元;
  4. 车载电源:12V电源系统,抑制发电机波动、负载突变产生的尖峰电压。

总结

SMCJ28CA-AT/TR13凭借汽车级可靠性、双向防护能力与紧凑封装,成为车载电子过压防护的高性价比选择,适用于对瞬态干扰敏感的各类车载应用场景。

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
