1N4148WS-2 产品概述
一 概述
1N4148WS-2 是 BORN（伯恩半导体）推出的独立式开关二极管，采用 SOD-323 小型封装，针对高速开关与信号整流场合优化设计。器件在150mA工作电流下正向压降约1.25V，反向耐压71V，兼顾体积、速度与耐压性能，适合移动设备、通讯模块与工业控制等轻载高速应用。
二 主要特性
- 独立式开关二极管设计，SOD-323 紧凑封装。
- 正向压降 Vf = 1.25V（IF = 150mA），低功耗损耗与良好导通性能。
- 反向耐压 Vr = 71V，适应较高反压场景。
- 低反向电流 Ir = 1μA（常温），保证漏电小，信号完整性好。
- 反向恢复时间 Trr = 4ns，适合高速开关和脉冲应用。
- 非重复峰值浪涌电流 Ifsm = 2A，可承受短时冲击电流。
- 最大整流电流 150mA，耗散功率 Pd = 200mW。
三 电气特性说明
器件在150mA持续工作时的功耗约为0.1875W（1.25V×0.15A），接近封装额定耗散200mW上限。因此在实际设计中应注意平均功率与散热条件，避免长时间满载工作。4ns 的反向恢复时间保证在数十MHz 级别的开关频率下仍有良好切换性能。
四 封装与热管理
SOD-323 为表面贴装微型封装，适合高密度 PCB。由于封装限制，热阻相对较大，建议为二极管提供良好铜箔散热路径、合理的焊盘面积和必要的散热层。波峰或回流焊工艺兼容，但需遵循厂商推荐的焊接温度曲线以防止器件损伤。
五 典型应用
- 高速信号整流与保护电路
- 通信终端与接口保护（限流、钳位）
- 移动和便携式电子设备的开关与隔离
- 工业控制与测量电路中的快速整流
六 使用注意事项
- 持续整流电流不宜长期接近150mA，建议留有裕度以延长寿命。
- 高反向电压边界应用应考虑温度升高对 Ir 的提升影响。
- 在有反复大电流冲击的场合，注意峰值 Ifsm 与封装热容限制。
- PCB布线时应保证焊盘散热良好并避免与高温元件近邻影响。
七 选型建议与订购信息
选型时若需更高电流或更低正向压降，可考虑大封装或功率更高的替代型号；若需要更高耐压或更快恢复，可选择专用快恢复或肖特基器件。订购时请确认型号 1N4148WS-2、品牌 BORN、封装 SOD-323 与相关参数一致，索取并参考厂商完整数据手册以获取详细的最大额定值和焊接规范。

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.
