1SS355 产品概述
一、概述
1SS355 是时科（SHIKUES）提供的一款独立式开关二极管，采用 SOD-323 小封装，面向高频开关与小功率整流场景。器件以快速反向恢复、低反向漏电和适中的正向压降为特点，适用于对体积、速度及可靠性有要求的消费电子与通信终端电路。
二、主要电气参数
- 二极管配置：独立式（Discrete）
- 正向压降 Vf：1.2 V @ If = 100 mA
- 直流反向耐压 Vr：80 V
- 允许整流电流 If：100 mA（连续）
- 反向电流 Ir：100 nA @ 80 V
- 反向恢复时间 Trr：4 ns
- 非重复峰值浪涌电流 Ifsm：500 mA
- 封装：SOD-323（表面贴装）
三、产品特点
- 高频快速恢复（Trr≈4 ns），适合开关频率较高的电路。
- 低反向泄漏（100 nA @ 80 V），便于低功耗与精确信号路径设计。
- 小型化 SOD-323 封装，利于高密度 PCB 布局和小型消费类设备。
- 良好的浪涌承受能力（Ifsm 500 mA），满足短时浪涌保护需求。
四、典型应用场景
- 开关电源辅助整流与钳位回路。
- 高速开关和脉冲信号整流。
- 通信设备中的检波、限幅与保护电路。
- 便携式消费电子的低功耗整流和保护单元。
五、封装与使用建议
- SOD-323 小封装对焊接热量敏感，建议采用标准 SMD 回流曲线和推荐焊盘布局以保证焊接质量。
- 设计时注意 If（100 mA）为连续允许值，需考虑散热与 PCB 铜箔面积进行适当降额。短时浪涌可由 Ifsm 指标承受，但不可作为长期工作条件。
- 高频开关应用中应保证走线短、回路面积小，以降低寄生电感对开关性能的影响。
六、注意事项与可靠性
- 避免长期在高温、高反向电压下工作以降低 Ir 增大与寿命影响。
- 原厂信息为器件选型依据，实际电路中建议进行功率、热和开关应力的仿真与实测验证。
- 处理和贴装过程中采取防静电措施，按制造商规范存储和使用。
总结：1SS355（SHIKUES 时科，SOD-323）以其快速恢复特性、低漏电和小封装优势，适合需要高速开关和空间受限的低功率电子设计。
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.
