SS22（KUU）肖特基二极管 产品概述
一、产品简介
SS22 为 KUU 品牌的独立式肖特基整流二极管，封装为 SMA (DO-214AC)。该器件面向低压高速整流与反向保护场合，额定整流电流为 2A，直流反向耐压 Vr 为 20V，典型正向压降 Vf 为 550mV（在 If=2A 条件下），反向漏电流 Ir 为 500μA（在 Vr=20V 条件下）。
二、主要电气参数
- 正向压降（Vf）：0.55V @ If = 2A
- 最大整流电流（If）：2A（持续）
- 直流反向耐压（Vr）：20V
- 反向漏电流（Ir）：500μA @ Vr = 20V
- 器件类型：独立式肖特基二极管
三、器件特性与优势
SS22 属于肖特基结构，正向压降相对较低，导通损耗小，适合在较大电流下减少功耗与发热。响应速度快，开关损耗低，适用于高频开关、整流与反向保护。SMA 封装兼顾散热与 PCB 布局便利性，适合中等功率应用。
四、典型应用场景
- 开关电源（低压输出整流）
- 车载电子（反向保护与整流）
- 电池充放电保护电路
- DC-DC 转换器输出整流与续流二极管
- 电源管理模块及高频整流场合
五、封装与热管理
SMA (DO-214AC) 包装体积小，便于波峰/回流焊装配。尽管肖特基具有较低 Vf，但在额定 If 下仍产生热量，推荐在 PCB 设计中配合铜箔散热、短引线及必要的热过孔，确保结温不超过器件规格上限以维持可靠性。
六、设计与选型注意事项
选择 SS22 时需确认系统最大反向电压不超过 20V，并评估在最高工作电流下的正向压降及功耗。若工作环境温度较高或有更严格的反向漏电要求，可考虑更高 Vr 或更低 Ir 的替代型号。封装适配时注意焊接工艺与热循环可靠性。
如需详细的最大额定值、热阻或封装尺寸图（机械规格），建议参考厂商 Datasheet 以完成最终电路验证与热设计。

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.
