1N4148TR是FUXINSEMI(富芯森美) 推出的独立式开关二极管,采用DO-35轴向引线封装,属于通用型高频开关器件。作为经典开关二极管的实用衍生型号,其设计核心围绕「快速开关响应」与「低功耗导通」展开,兼顾小信号整流、过压保护等多元需求,是电子电路中高频信号处理、小功率电源及基础保护的常用器件。
正向压降(Vf)典型值为1V@10mA,属于低导通压降范畴——相比普通整流二极管(如1N4007的Vf≈1.2V@1A),在mA级小电流场景下可显著降低导通损耗,适配低功耗电路的信号传输与小电流整流需求。
反向恢复时间(Trr)仅4ns,这是开关二极管区别于普通整流管的核心指标——短恢复时间意味着在MHz级高频场景(如信号调制、脉冲整形)中,二极管能快速从导通切换至截止,避免信号延迟或失真。
工作结温范围覆盖**-55℃~+150℃**,符合工业级器件的宽温要求,可稳定工作于户外设备、车载电子等极端环境,无需额外降额使用。
1N4148TR采用DO-35轴向引线封装,具备以下优势:
凭借4ns短恢复时间,适用于信号调制、脉冲整形、高速逻辑接口(TTL/CMOS)等场景,避免高频信号失真。
150mA平均电流+100V反向耐压,可满足智能穿戴、传感器模块等低功耗设备的小功率整流需求,替代部分高成本专用器件。
100V反向耐压+2A浪涌能力,可用于ESD静电保护、电源过压钳位,防止电路因瞬间过压/过流损坏。
1V正向压降适配3.3V/5V逻辑信号的钳位,将信号幅度限制在安全范围,避免后级电路过载。
1N4148TR以其「快速开关+宽温适应+低损耗」的综合优势,成为电子设计中高频信号处理、小功率电源及基础保护的实用选择。

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.
