1SS355 产品概述 — YONGYUTAI（永裕泰）
一、产品简介
1SS355 是永裕泰（YONGYUTAI）推出的一款独立式高速开关二极管，采用 SOD-323 超小封装，面向便携式电子、通信终端、信号处理与保护电路等对开关速度与体积有严格要求的应用场景。典型运行点为正向压降 Vf = 1.2V（IF = 100mA），在小信号和开关场合表现稳定。
二、主要电气参数
- 正向压降：Vf = 1.2V @ IF = 100mA
- 额定整流电流：IF(AV) = 100mA
- 非重复峰值浪涌电流：IFSM = 500mA
- 直流反向耐压：VR = 80V
- 反向漏电流：IR = 100nA @ VR = 80V
- 反向恢复时间：Trr ≈ 4ns
这些参数表明该器件适合高频快速切换、低漏电要求的设计。
三、产品特点
- 响应快：Trr 约 4ns，适合 MHz 级及以上的信号切换与整流。
- 低漏电：在 80V 下 IR 仅 100nA，利于低静态功耗设计。
- 小体积：SOD-323 封装，适配高密度 PCB 布局与便携设备。
- 耐压与浪涌：80V 反向耐压与 500mA 峰值浪涌能力，兼顾可靠性与瞬态承受。
四、典型应用
- 开关电路、脉冲整形与高速信号整流。
- 逻辑电平移位、采样保持电路中的钳位/切换元件。
- 输入保护、反向保护与窄脉冲钳位。
- 移动设备、消费电子与通信终端的小信号二极管需求。
五、封装与装配建议
- 封装：SOD-323，利于回流焊自动化贴装。
- 热管理：虽为小封装，但额定整流电流仅 100mA，设计时应按实际功耗考虑焊盘散热与周边铜箔面积，避免长期高电流运行导致温升。
- 焊接规范：遵循无铅回流曲线，避免过高峰温或长时间回流导致封装应力。
六、选型与可靠性提示
- 若电路中存在持续大电流或更高浪涌要求，建议选用更高 IF(AV) / Ifsm 规格器件。
- 在高温或高电压环境下注意漏电与反向击穿裕量，必要时加并联/串联保护元件或限流电阻。
- 储存与贴片前注意防潮处理，避免受潮导致焊接缺陷。

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.
