SMAJ54CA/TR13是台湾君耀(Brightking)推出的双向瞬态抑制二极管(TVS),采用SMA(DO-214AC)表面贴装封装,专为54V工作电压系统的瞬态过压防护设计,核心作用是快速钳位浪涌电压,保护后端敏感电子元器件免受雷击、ESD、电源瞬变等异常冲击。
作为TVS器件,SMAJ54CA/TR13的核心功能是瞬态过压防护:当电路中出现瞬间过压(如雷击感应、开关瞬态、静电放电)时,器件能在纳秒级时间内从截止状态快速击穿导通,将过压钳位到安全范围,避免后端IC、传感器、通信模块等敏感元件因过压损坏。
其双向极性设计,支持正负两个方向的过压防护,无需区分安装极性,适配单极性或双极性电路的防护需求。
SMAJ54CA/TR13的电气参数精准匹配54V系统的防护要求,核心参数及意义如下:
SMAJ54CA/TR13采用SMA(DO-214AC)表面贴装封装,具备以下优势:
结合参数特性,SMAJ54CA/TR13主要应用于54V电压等级的过压防护场景,典型包括:
综上,SMAJ54CA/TR13以双向防护、精准钳位、小封装等特性,成为54V系统过压防护的高性价比选择,广泛适配工业、通信、汽车电子等领域的小型化设计需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
