SK810 产品概述
一、概览
SK810 为 CJ（江苏长电/长晶）推出的一款肖特基整流二极管，额定直流整流电流 8A，直流反向耐压 100V。该器件采用 SMCG 封装，面向开关电源、DC-DC 转换器、整流桥及电源保护等中大功率应用场景，兼顾导通损耗与开关性能。
二、主要参数
- 正向压降 Vf：950mV @ 8A
- 直流反向耐压 Vr：100V
- 连续整流电流 Io：8A
- 非重复峰值浪涌电流 Ifsm：200A
- 工作结温范围：-55℃ ~ +150℃
- 封装：SMCG，品牌：CJ（江苏长电/长晶）
三、关键特性
- 低正向压降：在高电流条件下 Vf≈0.95V，能有效降低导通损耗，提升系统效率。
- 快速恢复特性：肖特基结构无明显反向恢复，可减小开关损耗与电磁干扰。
- 耐冲击能力：200A 的峰值浪涌电流能力适用于瞬态吸收与整流浪涌。
- 宽温度范围及工业级可靠性，适合苛刻工况。
四、典型应用
- 开关电源主整流/续流二极管
- DC-DC 降压/升压转换器输出整流
- 逆向保护与电源 OR-ing
- 充电器、LED 驱动及汽车电子（在满足温度与抗浪涌要求下）
五、散热与可靠性建议
SMCG 封装对散热依赖 PCB 铜箔面积与散热通孔。推荐：
- 在器件下方和焊盘周围使用大面积铜箔并增加多孔过孔与铜柱焊点，降低结-壳温差。
- 在高 ambient 或持续大电流工况下按数据手册进行电流热降额（derating）。
- 注意肖特基在高温下反向泄漏电流显著上升，应在热设计中留余量。
六、封装与选型提示
SMCG 兼顾散热与自动化贴装，适用于回流焊工艺。选型时关注实际工作电流峰值、平均功耗及浪涌水平，必要时在并联或选用更大电流等级器件以降低损耗与温升。同时核对完整数据手册中的典型波形、最大结温与封装尺寸以便 PCB 布局。
七、典型电路与注意事项
在开关电源输出或续流回路中，注意加旁路/吸收电容抑制尖峰、电压回弹。对于输入整流，请评估浪涌电流能力并考虑在输入端增加限流或热敏电阻以保护器件。最终应用中，请以 CJ 官方数据手册为准，验证实际温升与长期可靠性。

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.
