SMCJ54CA 产品概述

一、产品简介

SMCJ54CA 是台舟电子(TECH PUBLIC)推出的一款双向瞬态电压抑制二极管(TVS),采用 SMC 封装,面向工业级和通信级浪涌保护需求。器件在工作电压 54V 条件下提供快速限制电压峰值,能有效吸收雷击和开关瞬态能量,保护下游电子元件免受过压损坏。

二、主要参数

  • 极性:双向
  • 反向截止电压 Vrwm:54V
  • 钳位电压 Vcl:87.1V
  • 击穿电压 VBR:66.3V
  • 峰值脉冲电流 Ipp:17.2A @ 10/1000µs
  • 峰值脉冲功率 Ppp:1.5kW @ 10/1000µs
  • 反向电流 Ir:5µA(典型)
  • 工作温度范围:-55℃ ~ +150℃
  • 封装:SMC(表面贴装)

三、性能特点

  • 双向结构,适用于交流或双极性脉冲抑制场景;
  • 低反向漏电流,有利于在待机或精密电路中保持低损耗;
  • 高吸收能量能力(1.5kW @10/1000µs),可承受工业级浪涌和雷电脉冲;
  • SMC 封装便于自动化贴装与散热管理,可靠性高,适合长时间运行环境。

四、典型应用

  • 48V 及 54V 直流供电系统(如 PoE、通信基站、备电系统)保护;
  • 工业控制与电力电子接口浪涌保护;
  • 逆变器、太阳能阵列与储能系统的过压防护;
  • 电源模块输入、信号线与继电器驱动电路的瞬态抑制。

五、安装与注意事项

  • 建议靠近被保护端口布置 TVS,最短走线以降低感抗与寄生电阻;
  • 保持良好散热路径,必要时配合散热铜箔或散热片使用;
  • 在高能脉冲环境下,配合熔断器或限流器使用以避免重复应力损伤;
  • 注意同类器件的反向截止电压与系统工作电压匹配,防止误触发或保护不足。

六、选型提示

选择时关注 Vrwm 与系统工作电压的余量、钳位电压对被保护器件的容忍度、以及脉冲测试条件(10/1000µs)是否与实际浪涌谱相符。SMCJ54CA 适合 48V 级别及附近电压系统的通用浪涌防护需求。

七、可靠性与环境适应

器件支持宽温范围(-55℃~+150℃),适应工业级温度循环与长期运行。建议在高湿或腐蚀性环境中配合封装或防护涂层使用,以延长可靠寿命。

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
