1N4148WS 产品概述
一、产品简介
1N4148WS 是一款由 FUXINSEMI（富芯森美）推出的高可靠性开关二极管，属于独立式小信号开关器件。该器件以 SOD-323（SC-90）小型贴片封装提供，适合空间受限的表面贴装电路板。凭借快速的反向恢复特性与低漏电流，适用于高速开关和小电流整流等场合。
二、主要电气参数
- 工作结温范围：-55 ℃ ~ +150 ℃（Tj）
- 正向压降：Vf = 1.25 V @ IF = 150 mA
- 直流整流电流：IF = 200 mA
- 非重复峰值浪涌电流：Ifsm = 2 A（瞬态、非重复）
- 直流反向耐压：Vr = 75 V
- 反向电流：Ir = 1 μA @ Vr = 75 V
- 反向恢复时间：Trr = 8 ns
- 耗散功率：Pd = 200 mW
以上参数表明该器件在小电流、高速开关应用中具备良好性能，同时在较高的反向电压下维持低漏电。
三、封装与热特性
1N4148WS 采用 SOD-323（SC-90）封装，体积小、引脚间距紧凑，便于高密度组装。最大耗散功率为 200 mW，设计时需注意器件的热阻与PCB散热路径，避免长期在极限功率下工作，以保证长期可靠性。
四、典型应用场景
- 高速逻辑开关与脉冲整形电路
- 信号钳位、限幅与采样电路
- 小电流整流与保护电路
- 通信设备、仪表及便携终端中的信号处理
五、可靠性与使用建议
在回流焊接时建议遵循标准无铅工艺曲线，避免超温或超时操作。布局时应保证良好地线和散热路径，并根据实际温升选择合适的工作条件。对于关键电路，建议在样机验证中评估温度、浪涌与长时间工作下的性能变化。
六、采购与型号说明
型号：1N4148WS；品牌：FUXINSEMI（富芯森美）；封装：SOD-323（SC-90）。订购时请确认完整规格书与批次一致性，如有更高电流或更低正向压降需求，可咨询供应商获取替代型号或定制方案。

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.
