1SS400G 产品概述
一、产品简介
1SS400G 为 CJ（江苏长电/长晶）推出的一款独立式开关二极管，封装为 SOD-723。该器件针对高速开关与低功耗小信号整流场景优化，体积微小、适合高密度表贴电路板。典型应用包括高速开关电路、信号钳位、低电流整流与电路保护等。
二、主要电气参数
- 正向压降（Vf）：1.2 V @ If = 100 mA
- 直流反向耐压（Vr）：80 V
- 直流整流电流：100 mA（连续）
- 非重复峰值浪涌电流（Ifsm）：2 A（单次、非重复）
- 反向电流（Ir）：100 nA @ 80 V
- 反向恢复时间（Trr）：4 ns
- 耗散功率（Pd）：100 mW
这些参数表明 1SS400G 在高达几十兆赫兹的开关环境中表现良好，反向漏电小，适用于对静态电流要求严格且对开关速度有要求的应用。
三、产品特点
- 小型 SOD-723 表贴封装，节省 PCB 面积，利于高密度布局。
- 低反向漏电（100 nA @ 80 V），适合高阻抗或计量电路使用。
- 快速恢复（Trr = 4 ns），能有效降低开关损失与交越失真。
- 最大连续正向电流 100 mA，适合信号整流与小电流保护用途。
- 单次浪涌能力 2 A，可承受瞬时冲击但不适合持续大电流环境。
四、典型应用场景
- 高频开关和快速切换信号路径（例如开关电源的辅助电路）。
- 信号钳位与保护（防止反向或过压进入敏感电路）。
- 低电流整流与电荷抽取场合（采样电路、检测电路）。
- 便携设备、传感器前端与低功耗模块的反向保护。
五、设计与选型建议
- 由于 Pd 仅 100 mW，应严格控制持续功耗与稳态电流，不建议长时间接近最大 100 mA。
- 若电路存在频繁或较大浪涌（超过 Ifsm 2 A），优先考虑更大封装或更高浪涌能力的器件。
- 若需要更低的正向压降以减小功耗，可选用 Schottky 二极管；若需要更高电压或更大电流，请选用更高等级产品。
- 布局时尽量缩短走线，确保良好散热和可靠焊点，避免局部升温影响可靠性。
六、焊接与可靠性注意
- SOD-723 为微型封装，推荐按照器件供应商提供的回流焊曲线和焊接工艺进行贴装。
- 处理与安装时注意静电防护（ESD），并按湿敏等级（MSL）保持器件干燥存放以防吸湿回流时发生焊接缺陷。
- 在高温或高湿环境下应考虑器件的长期漂移，关键电路可做冗余或定期校准。
七、总结
1SS400G 是一款面向小信号、高速开关与低功耗场合的开关二极管，具有 80 V 反向耐压、低漏电和 4 ns 的快速恢复特性。其 SOD-723 小体积适合空间受限的便携与消费类电子产品，但因功耗与电流等级有限，设计时需注意热管理与电流裕量。根据具体电路需求，合理选型与布局即可发挥其体积小、速度快、漏电低的优势。

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.
