Brightking SMCJ7.5A/TR13 瞬态抑制二极管(TVS)产品概述

Brightking(台湾君耀)SMCJ7.5A/TR13是一款专为电子设备瞬态过压防护设计的单向瞬态抑制二极管(TVS),凭借紧凑的SMC封装、宽温可靠性与平衡的防护参数,适配消费电子、工业控制、汽车电子等多领域的浪涌/ESD防护需求,是高性价比的过压防护解决方案。

一、核心定位与品牌背景

TVS作为瞬态过压防护的核心器件,通过快速导通钳位电压,将浪涌能量泄放至地,避免后端敏感电路(如MCU、芯片)损坏。SMCJ7.5A/TR13属于Brightking SMCJ系列贴片TVS,该系列以“小体积、高功率、宽温可靠”为核心特点,广泛应用于高密度PCB设计场景。

Brightking作为台湾老牌被动元件厂商,专注过压防护器件研发生产超过20年,产品符合IEC、JEDEC等国际标准,在汽车电子、工业控制领域拥有成熟的市场验证,品质一致性与可靠性得到行业认可。

二、关键电气参数解析

SMCJ7.5A/TR13的参数设计精准匹配低电压电路的防护需求,核心参数如下:

  • 极性:单向设计,适用于单方向过压防护(如电源正负极方向的浪涌),无需额外考虑双向防护的成本与空间;
  • 反向截止电压(Vrwm):7.5V,即器件正常工作时可承受的最大反向直流电压,适配5V、6V等低电压工作电路,避免设备正常电压下误触发;
  • 击穿电压(Vbr):8.33V,反向电压达到此值时器件快速导通,开启防护功能,与Vrwm的差值(0.83V)保证了正常工作与防护的切换可靠性;
  • 钳位电压(Vc):12.9V(典型值),浪涌峰值时器件两端的最大电压,是防护效果的核心指标——低钳位电压可有效保护后端芯片(多数芯片的最大承受电压为15V左右);
  • 峰值脉冲电流(Ipp):116.3A(8/20μs波形),即器件能承受的最大瞬态浪涌电流,满足多数设备的雷击、开关浪涌防护需求;
  • 峰值脉冲功率(Ppp):1.5kW@10/1000μs,针对慢速浪涌波形(如电源开关浪涌)的功率耐受能力,覆盖工业现场常见的浪涌场景;
  • 反向漏电流(Ir):100μA@Vrwm,正常工作时的反向漏电流极小,不影响设备功耗与续航;
  • 工作温度:-65℃~+150℃,宽温范围适配极端环境(如汽车发动机舱、工业高温车间)。

三、封装与可靠性设计

  • 封装形式:SMC(DO-214AB)贴片封装,尺寸约4.5mm×2.7mm×1.8mm,体积紧凑,支持SMT自动化生产,可显著节省PCB空间,适配手机、笔记本、汽车ECU等高密度设计;
  • 可靠性设计:器件经过严格的老化与一致性测试,击穿电压偏差控制在±5%以内,漏电流稳定;SMC封装的引脚采用抗振动设计,可承受工业振动与汽车行驶中的机械应力,适合移动设备与 harsh环境应用。

四、典型应用场景

SMCJ7.5A/TR13的参数与封装特点,使其适配以下场景:

  1. 消费电子:手机、平板电脑、笔记本电脑的电源端口、USB/HDMI等数据接口,防护ESD与电源浪涌;
  2. 工业控制:PLC、传感器、伺服驱动器的电源输入,应对工业现场的雷击浪涌与开关浪涌;
  3. 汽车电子:车载信息娱乐系统、车身控制器(BCM)的低电压线路(如5V传感器电路)防护;
  4. 通信设备:路由器、交换机的电源与射频接口,防止雷电感应过压损坏。

五、产品优势与市场价值

SMCJ7.5A/TR13在同类产品中具备以下优势:

  • 防护与功耗平衡:1.5kW功率耐受能力满足多数场景,100μA漏电流不增加设备功耗;
  • 宽温可靠性:-65~150℃覆盖极端环境,减少不同温度下的性能波动;
  • 成本效益:SMC封装降低PCB设计成本,Brightking的成熟工艺保证性价比;
  • 品牌保障:成熟的市场验证与品质一致性,降低售后风险。

综上,Brightking SMCJ7.5A/TR13是一款性能均衡、可靠性高的单向TVS,可有效解决电子设备的瞬态过压问题,是消费电子、工业控制、汽车电子等领域的理想防护选择。

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
