1N4148W 产品概述
一、引言
1N4148W是一款广泛应用于各种电子设备中的开关二极管，由于其卓越的性能和可靠性，成为了许多设计师的首选元器件。本文将详细介绍1N4148W的主要特性、应用场景及其优缺点。
二、产品特点
基本参数
- 正向电压 (Vf)：1.25V在150mA下，表明该二极管在标准工作条件下能够稳定提供较低的导通电压，适合低功耗电路。
- 反向耐压 (Vr)：75V，指在反向偏置情况下，1N4148W能够承受的最大电压。这一参数使其在许多高电压应用中具有良好的性能。
- 反向泄漏电流 (Ir)：在75V时为2.5μA，反向泄漏电流的低值提高了其在静态情况下的能效表现，减少了功耗。
- 最大正向电流 (If)：150mA，确保其在电流负载较大的情况下仍能可靠工作。
封装规格
- 封装类型：SOD-123。该封装形式不仅体积小、重量轻，而且具备优良的热特性和电气性能，适合现代紧凑型电路设计。
品牌背景
- 品牌：LGE（鲁光）是一家享有盛誉的电子元器件制造商，以其高品质产品和卓越的客户服务而闻名。

- 反向恢复时间：在某些高速切换应用中，其反向恢复时间可能不如某些专用高速二极管，需谨慎选择。
五、总结
1N4148W是一款可靠的开关二极管，凭借其较低的正向电压、优秀的极速切换能力和良好的耐压性能，在众多电子应用中深受欢迎。针对设计师而言，把握好其主要特性及适用领域，将能更好地应用于各类电子产品中，实现更高的设计效率与电路性能。无论是在消费电子、汽车电子还是其他领域，1N4148W都能为其提供可靠的解决方案，在电子技术日新月异的今天，继续发挥其重要作用。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
