SMAJ22CA/TR13(君耀Brightking)双向TVS二极管产品概述

一、产品核心定位与典型应用场景

SMAJ22CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),核心定位为小型化、宽温适用的过压防护器件,专为电子设备的电源端口、信号接口等场景提供瞬态浪涌(雷击、静电放电、开关浪涌)的快速抑制,避免后端敏感元器件(IC、传感器、显示模组)被过压击穿损坏。

其典型应用覆盖三大领域:

  1. 消费电子:智能手机、平板电脑、笔记本电脑的充电接口(USB Type-C/A)、耳机接口,防护静电放电(ESD)及电源浪涌;
  2. 工业控制:PLC模块、传感器节点、工业电源的输入端口,应对工业环境中的浪涌干扰(符合IEC 61000-4-5标准);
  3. 汽车电子:低压(12V/24V)车载设备(中控屏、胎压传感器)的辅助电路,适配-65℃~+150℃宽温,满足汽车级可靠性要求。

二、关键电性能参数深度解析

SMAJ22CA/TR13的电性能参数经过优化,平衡了防护能力与电路兼容性,核心参数及实际意义如下:

2.1 电压类参数:防护阈值与钳位精度

  • 双向极性:无需区分正负极,简化电路设计,适合交流/直流双向过压场景(如交流电源端口、差分信号接口);
  • 反向截止电压(Vrwm=22V):正常工作时反向漏电流仅1μA,不影响电路运行,适配12V/24V低压系统;
  • 击穿电压(Vbr=24.4V):Vrwm的1.1倍左右(TVS典型特性),保证过压触发一致性,避免误触发;
  • 钳位电压(Vc=35.5V):8/20μs脉冲峰值下的钳位电压,将过压限制在后端器件(3.3V/5V IC)耐受阈值内,是防护有效性的核心指标。

2.2 脉冲耐受能力:抗浪涌容量

  • 峰值脉冲电流(Ipp=11.3A):模拟雷击浪涌(8/20μs波形)的峰值电流耐受能力,可抑制常见浪涌强度;
  • 峰值脉冲功率(Ppp=400W):Ipp与Vc的乘积(≈11.3A×35.5V),直接反映脉冲功率容量,满足多数消费电子与工业设备需求。

2.3 环境与可靠性参数

  • 反向漏电流(Ir=1μA):Vrwm下漏电流极低,不增加系统功耗或信号干扰;
  • 工作温度范围(-65℃~+150℃):宽温设计,覆盖工业级(-40℃+85℃)及汽车级(-55℃+150℃)温度需求,适应恶劣环境。

三、封装与工艺优势

SMAJ22CA/TR13采用SMA(DO-214AC)贴片封装,具有以下设计优势:

  1. 小型化:封装尺寸仅2.9mm(长)×1.7mm(宽)×1.1mm(高),适合高密度PCB设计(如智能手机主板、小型传感器模块);
  2. 焊接兼容性:无铅无卤工艺,符合RoHS标准,兼容回流焊、波峰焊等常规贴片工艺,量产效率高;
  3. 机械可靠性:陶瓷/塑料复合封装结构,抗振动、抗冲击能力强,满足工业与汽车设备的机械可靠性要求。

四、品牌与品质保障

台湾君耀(Brightking)是全球知名的防护器件厂商,SMAJ22CA/TR13继承了其成熟的品质体系:

  • 一致性:批量生产参数离散性小,避免器件差异导致的防护失效;
  • 标准合规:符合IEC 61000-4-2(ESD)、IEC 61000-4-5(浪涌)等国际电磁兼容标准;
  • 售后支持:提供完整datasheet及应用指导,适合OEM/ODM厂商的量产需求。

总结

SMAJ22CA/TR13双向TVS二极管以小体积、宽温、高防护能力、双向兼容为核心优势,精准匹配消费电子、工业控制、汽车电子等领域的过压防护需求。其平衡的电性能参数与可靠的封装设计,使其成为低压系统中高性价比的瞬态防护解决方案,可有效降低电子设备的浪涌损坏风险,提升产品稳定性。

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
