SMAJ190CA/TR13 产品概述

一、性能概述

SMAJ190CA/TR13 是一款双向瞬态电压抑制二极管(TVS),由 Brightking(台湾君耀)生产,专为表面贴装(SMA / DO-214AC)应用优化。器件采用薄型封装与玻璃钝化结结构,具有低电感、快速响应和出色的钳位能力,能够在10/1000μs波形下承受高达400W的峰值脉冲功率(重复率/占空比:0.01%),适用于对电路板空间与冲击能力有严格要求的场合。

二、主要电气参数

  • 极性:双向(适用于交流或反向瞬变)
  • 反向截止电压 Vrwm:190 V(工作电压)
  • 击穿电压 VBR:211 V(典型/测试条件下)
  • 钳位电压:308 V(在规定峰值脉冲条件下)
  • 峰值脉冲电流 Ipp:1.3 A(10/1000μs)
  • 峰值脉冲功率 Ppp:400 W(10/1000μs,0.01% 占空比)
  • 反向漏电流 Ir:1 μA(在 Vrwm 条件下的典型值)
  • 工作温度范围:-65 ℃ 至 +150 ℃

三、封装与热机械特性

  • 封装形式:SMA(DO-214AC),适合自动贴装与回流焊工艺
  • 封装特点:薄型、低高度、有利于紧凑电路板布局
  • 玻璃钝化结提供良好的长期可靠性与稳定的反向特性
  • TR13 后缀表示卷装(Tape & Reel)包装,便于SMT生产线使用

四、典型应用场景

  • I/O 接口保护:数据线路、串行/并行接口的差分或共模浪涌抑制
  • AC / DC 电源防护:交流供电线路或高压直流总线的瞬变钳位
  • 工业与通信设备:对雷击浪涌、电磁兼容(EMC)及开关瞬变的防护
  • 任何需在190V工作电压附近提供双向瞬态抑制的场景

五、选型与使用建议

  1. 工作电压匹配:Vrwm=190V,选择器件时应确保其在系统最大静态电压下工作,并留有安全裕度。
  2. 钳位与吸收能力:钳位电压308V 表明在规定脉冲下最大电压幅度;若系统对电压敏感,应选择更低钳位或增加串联限流元件。
  3. 布局与焊接:将 TVS 尽量靠近需保护的引脚或接口放置,使用宽短走线与多过孔回流至地线以降低寄生电感。
  4. 热与重复冲击:400W 为瞬态脉冲能力(10/1000μs,0.01% 占空比),不作为连续功率使用;注意冲击重复频次与热积分。
  5. 双向接入:用于交流或两极反向冲击场合,无极性限制,但在单向直流系统也可采用双向器件,注意正负方向电气特性对称性。

六、可靠性与环境特性

  • 宽温范围(-65~+150℃)适用于工业级与严苛环境。
  • 低漏电流(1 μA)有利于高阻抗与低功耗电路的长期稳定性。
  • 玻璃钝化工艺提高抗湿热与长寿命性能。

七、订购与注意事项

  • 品牌:Brightking(台湾君耀)
  • 型号:SMAJ190CA/TR13(TR13 表示卷带盘装,便于自动化贴装)
  • 在设计前务必参考厂商完整数据手册(包括最大额定、测试条件、典型波形与封装尺寸),并在实际系统中做浪涌试验验证以确认钳位与温升满足要求。

如需依据具体系统(例如最大允许钳位、电源拓扑或特定脉冲波形)进行更详细的选型或并联/串联使用建议,可提供电路参数以便给出针对性设计建议。

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
