SS14整流二极管产品概述

一、核心电气参数解析

SS14是一款小功率整流二极管,核心参数精准匹配低压小电流应用场景,关键指标如下:

  • 整流电流:额定连续整流电流1A,满足普通LED驱动、小型开关电源等小功率设备的电流需求,避免过载风险;
  • 正向压降:550mV(@1A),远低于传统硅整流二极管(通常700mV以上),导通损耗显著降低,直接提升电源转换效率;
  • 反向耐压:直流反向耐压40V,覆盖低压直流电路的反向电压需求(如锂电池、低压电源),避免反向击穿损坏;
  • 反向漏电:300μA(@40V),反向漏电极小,减少静态功耗,提升电路长期工作的稳定性;
  • 浪涌能力:非重复峰值浪涌电流30A,可承受开机瞬间、负载突变等瞬间过流冲击,保护电路不被烧毁;
  • 温度范围:工作结温-55℃~+125℃,宽温域适应极端环境(如户外设备、汽车电子),避免高低温下性能衰减。

二、封装与品牌背景

  • 封装类型:采用SMA(DO-214AC)贴片封装,体积小巧(约2.7×1.7mm),适合高密度PCB布局,兼容自动贴装工艺,降低生产难度;
  • 品牌介绍:由国产功率半导体品牌YONGYUTAI(永裕泰)生产,该品牌专注整流二极管、MOS管等器件研发,以高性价比、稳定质量著称,产品广泛应用于消费电子、工业控制、汽车电子等领域。

三、典型应用场景

SS14的参数特性使其适配多类低压小功率电路,典型场景包括:

  1. 开关电源:作为续流二极管或整流二极管,低正向压降减少电源损耗,30A浪涌能力应对开机瞬间冲击,提升电源效率;
  2. LED驱动电路:小功率LED驱动的整流环节,1A电流满足多颗LED串联/并联需求,40V耐压适配低压驱动电源(如5V/12V);
  3. 小家电控制板:电磁炉、豆浆机等设备的电源整流,宽温范围适应厨房高低温环境,贴片封装节省控制板空间;
  4. 电池保护电路:锂电池反向保护二极管,防止过充/过放时的反向电流,40V耐压满足锂电池(3.7V/4.2V)的保护需求;
  5. 汽车电子辅助电路:车载USB充电、仪表盘背光的整流环节,-55125℃结温适应汽车高低温工况(-4085℃),提升车载设备可靠性。

四、性能优势总结

  • 高效率:低正向压降(550mV@1A)降低导通损耗,尤其适合对效率敏感的小功率电路(如便携式设备);
  • 高可靠性:宽结温、低漏电、强浪涌能力,减少电路故障风险,延长设备使用寿命;
  • 易集成:SMA贴片封装体积小,兼容自动贴装,适配小型化电子设备的高密度设计;
  • 宽适配:40V耐压、1A电流覆盖多数低压小功率场景,无需额外匹配其他器件。

五、质量与环保标准

SS14符合RoHS环保标准(无铅无镉),通过高低温循环、浪涌测试等可靠性验证,满足工业级质量要求,可稳定应用于各类消费电子及工业设备中。

综上,SS14是一款性价比高、可靠性强的小功率整流二极管,精准适配低压小电流应用,是开关电源、LED驱动等场景的优选器件。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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.

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.

Replenishment inquiry Typical RFQ workflow
