K1N5817HWS-7-F 肖特基二极管产品概述

一、产品基本定位与核心身份

K1N5817HWS-7-F是KUU品牌推出的独立式肖特基整流二极管,专为低电压、小功率但需高效整流的应用场景设计。作为肖特基二极管家族中的一员,其核心优势在于低正向压降与快速开关特性,同时采用超小型表面贴装封装,适配高密度PCB布局需求,是便携式电子、小型电源模块等领域的理想选择。

二、关键电性能参数详解

该器件的电性能参数针对低压高效整流进行了优化,核心参数及意义如下:

2.1 正向导通特性

正向压降(Vf)仅为750mV@3A,远低于普通硅PN结二极管(通常1V以上)。这一特性源于肖特基二极管的金属-半导体接触机制,导通时无需克服PN结的势垒,因此压降更低,可显著降低整流过程中的功率损耗,减少器件发热,提升电源转换效率。

2.2 反向耐压与漏电流

直流反向耐压(Vr)为20V,满足多数低压电源系统的反向截止需求;在额定反向电压下,反向漏电流(Ir)仅为1mA@20V,漏电流稳定且处于较低水平,可有效避免反向导通导致的能量损失,提升电路可靠性。

2.3 电流承载与浪涌能力

  • 直流整流电流(If):1A,可稳定承载1A持续工作电流,适配小功率电源输出;
  • 非重复峰值浪涌电流(Ifsm):10A,能够承受瞬间过流冲击(如电源启动瞬间的浪涌),降低器件因突发大电流损坏的风险,增强电路抗干扰能力。

三、封装与物理特性

K1N5817HWS-7-F采用SOD-323封装,这是一种超小型表面贴装封装,具有以下实用特点:

  1. 尺寸紧凑:典型封装尺寸约为1.6mm×0.8mm×0.6mm(长×宽×高),可大幅节省PCB空间,适合便携式设备、小型模块的高密度布局;
  2. 焊接兼容性:支持回流焊、波峰焊等标准表面贴装工艺,适配自动化生产流程;
  3. 环保合规:符合RoHS 6.0标准,无铅无卤,满足全球电子行业的环保要求;
  4. 机械可靠性:封装结构坚固,可承受一定的机械应力,适配振动环境(如汽车电子子系统)。

四、典型应用场景

结合参数特性,该器件主要适用于以下场景:

  1. 低压电源适配器:如5V/1A USB充电适配器,低Vf可降低整流损耗,提升充电效率;
  2. 便携式电子设备:智能手机、蓝牙耳机、智能手环等的电源管理模块,小封装适配设备小型化需求;
  3. 小型DC-DC转换器:低电压输入(如3.3V)的DC-DC电路中,作为整流管减少功率损耗;
  4. LED驱动电路:小功率LED照明(如台灯、夜灯)的整流环节,低发热避免影响LED寿命;
  5. 汽车电子子系统:车载USB充电口、小型传感器模块的电源整流,耐浪涌能力适配汽车启动瞬间的电流波动。

五、产品核心优势总结

  1. 高效低耗:750mV低正向压降,降低导通损耗与发热,提升系统能效;
  2. 小型化适配:SOD-323超小封装,满足高密度PCB设计需求;
  3. 可靠性强:稳定的反向漏电流与10A浪涌能力,适应复杂工作环境;
  4. 工艺兼容:支持标准表面贴装工艺,便于批量生产;
  5. 环保合规:符合RoHS标准,适配全球市场要求。

该器件通过优化电性能与封装设计,在低压小功率整流场景中实现了效率与空间的平衡,是同类应用的高性价比选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
