SMBJ54CA/TR13(Brightking 台湾君耀)产品概述

一、产品简介

SMBJ54CA/TR13 是 Brightking(台湾君耀)生产的一款双向瞬态电压抑制二极管(TVS),封装为 SMB(DO-214AA)。该器件专为抑制线路上的瞬态过电压浪涌而设计,适用于直流和交流两极性瞬态事件的抑制保护。典型用于电源输入、数据/信号线和工业总线的浪涌防护。

二、主要电气参数

  • 极性:双向(双向钳位,正负瞬态均可保护)
  • 额定反向工作电压 Vrwm:54 V
  • 击穿电压 Vbr:60 V(典型/保证范围按厂家资料)
  • 钳位电压 Vc(在指定脉冲条件下):87.1 V
  • 峰值脉冲电流 Ipp:6.9 A(对应 Vc 与 Ppp)
  • 峰值脉冲功率 Ppp:600 W(按厂家脉冲测试条件)
  • 反向漏电流 Ir:1 μA(在 Vrwm 条件下的典型值)
  • 封装:SMB(DO-214AA),便于自动贴装与回流/波峰焊接

三、产品特点与优势

  • 双向钳位:能够同时抑制正向和反向的过电压脉冲,适合交流系统或可能出现反向瞬态的场合。
  • 低漏电流:在额定工作电压下反向漏电流仅约 1 μA,有利于低功耗系统长期在线保护。
  • 高能量吸收能力:600 W 峰值脉冲功率配合 6.9 A 的峰值脉冲电流,能有效吸收常见的开关瞬态和雷击感应脉冲能量。
  • 标准 SMB 封装:体积适中,热耗散和机械强度良好,适合大多数工业与消费类电路板工艺。

四、典型应用场景

  • 电源输入保护(尤其是车载、工业电源输入)
  • I/O 接口与通信总线防护(CAN、RS-485、以太网边缘保护等)
  • 逆变器、伺服驱动器和电机控制器的瞬态抑制
  • 智能设备、仪表与楼宇自控系统的浪涌防护

五、选型与使用建议

  • 工作电压匹配:选择 Vrwm(54 V)应大于系统正常工作最大电压且留有裕量,避免在正常工作下频繁进入击穿区。
  • 钳位电压考虑:钳位电压 87.1 V 是在特定测试脉冲下的值,设计保护时要确认下游器件能承受该钳位水平或采用前置限流元件(熔断器、电阻)以降低峰值能量。
  • 布局注意:将 TVS 放置于被保护端靠近外部接口位置,焊盘短且回路电感小,以实现最佳浪涌吸收效果。
  • 热与可靠性:SMB 封装有一定散热能力,但连续或频繁高能脉冲会加速热应力,应保证足够散热与保护元件后备措施。

六、封装与可靠性

SMB(DO-214AA)为行业标准封装,便于 SMT 自动化生产。器件常以带卷(TR)形式供货,适合长线生产。Brightking 品质控制下,器件符合 TVS 常用电气可靠性测试,适合工业级应用。

七、总结

SMBJ54CA/TR13 是一款面向中低压系统的高能量双向 TVS,具有 54 V 工作电压、87.1 V 钳位、电流 6.9 A 和 600 W 峰值功率等特性,适合需要双向浪涌保护的电源和信号线路。在实际使用中,应合理评估系统承受的钳位电压与能量并优化 PCB 布局与散热设计,以发挥器件最佳防护效果。

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
