SMAJ5.0A/TR13 为 Brightking(台湾君耀)生产的一款单向 TVS 晶体管,采用 SMA(DO-214AC)封装,专为保护 5V 或类似低压直流电源及信号线免受瞬态过电压和浪涌冲击而设计。器件在正常工作时处于反向偏置状态,当瞬态电压超过击穿点时快速导通,将能量钳位到安全电平,从而保护下游电路。
SMA(DO-214AC)封装体积小、热阻低,适合自动化贴片生产。器件后缀 TR13 通常表示带卷盘(Tape & Reel)包装,便于 SMT 贴片机直接上料,适合批量生产。封装耐热并适应较宽的环境温度范围,适合工业级及高可靠性场合。
总结:SMAJ5.0A/TR13 以其对 5V 线的良好匹配、400W 的瞬态吸收能力和耐高温特性,适用于工业、通信及一般消费类电源与信号线的浪涌保护。在使用时请结合系统能量、漏电容忍度和散热条件进行全面评估,并遵循厂商焊接与储存规范以确保长期可靠性。

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.
