SS14HE 产品概述

一、产品简介

SS14HE 是 TECH PUBLIC(台舟电子)推出的一款小型 Schottky 整流二极管,采用 SOD-323HE 低电感、低剖面封装,面向便携电源及高密度电路板的整流与保护应用。该器件具有低正向压降和较高的瞬态浪涌能力,适合在空间受限且要求高效率的直流电路中替代普通硅整流器件,以降低功耗和发热。

二、主要参数摘要

  • 型号:SS14HE(品牌:TECH PUBLIC / 台舟电子)
  • 封装:SOD-323HE(小型表贴封装)
  • 正向压降 (Vf):550 mV @ 1.0 A
  • 直流反向耐压 (Vr):40 V
  • 最大整流电流:1 A(连续)
  • 反向漏电流 (Ir):500 μA @ 40 V
  • 非重复峰值浪涌电流 (Ifsm):30 A(短时浪涌,具体测量条件请参考厂方数据手册)
  • 工作结温范围:-55 ℃ ~ +125 ℃
  • 描述类别:未分类(标准 Schottky 整流二极管)

三、器件特点与优势

  1. 低正向压降:约0.55 V @ 1 A 的较低 Vf 可有效降低整流损耗,提升电源效率并减少发热,尤其适用于低压差供电场景。
  2. 小尺寸封装:SOD-323HE 小体积、低剖面设计,有利于高密度布板和便携设备的体积优化。
  3. 较强的浪涌能力:30 A 的短时峰值浪涌电流使其在启动或突发过载时能承受一定的冲击(仍须按数据手册规定的脉冲宽度与重复条件评估)。
  4. 宽工作温度:-55 ℃ 至 +125 ℃ 的结温范围保证器件在工业级温度环境下的可靠性。

四、典型应用场景

  • 开关电源的二次侧整流与续流二极管
  • 便携式设备(移动电源、平板、手机配件等)的输入整流与反极性保护
  • 电池管理与充电器线路中的低损耗整流
  • 功率路径选择、阻断回流与防反接电路
  • 工业控制及通信设备中对体积与效率有要求的小功率整流应用

五、电气与热设计要点

  • 正向压降随温度与电流变化明显:在设计中应根据最大工作电流和允许温升计算功耗(P ≈ Vf × I),并留有余量以保证在高温或高电流条件下的安全。
  • 反向漏电流随温度上升显著增加:在高温或高压偏置条件下(Ir = 500 μA @ 40 V 为典型室温参考值),需评估漏电对待机功耗或偏置精度的影响。
  • 浪涌和热重载:Ifsm 为短时峰值能力,连续或频繁的高幅值脉冲会造成器件过热甚至失效,应确保脉冲能量在允许范围内并进行必要的热散设计。
  • PCB 布局:为降低寄生电阻和热阻,应在二极管附近配备适当的铜箔散热区域,缩短电流回路,避免在狭长走线中产生额外压降和局部发热。

六、封装与安装建议

  • SOD-323HE 为薄型表贴封装,适合回流焊工艺。具体回流焊温度曲线与烘烤条件请参照厂方的焊接与湿度敏感性(MSL)说明。
  • 贴装时注意极性标识(阴极/阳极),避免反向安装;焊接后建议进行目视检查与必要的 X-ray 或飞针测试以保证焊点可靠性。
  • 对于高功率或需长期可靠运作的场合,建议在 PCB 设计时为器件留足散热面积并采用热过流保护策略。

七、可靠性与注意事项

  • 反向电压的余量设计:在 40 V 反向耐压下,实际应用中应留有安全裕度以避免因瞬态电压或浪涌导致击穿。
  • 漏电对电路影响:当用于高阻抗或低功耗电路时,需考虑漏电流对电源寿命或测量精度的影响。
  • 选择与替代:SS14HE 作为通用 1 A/40 V Schottky 可与类似规格的 SS14 系列器件互换,但在严格的热或漏电指标下应对比器件的实际曲线特性与数据手册。

八、采购与标识

建议在批量采购前索取 TECH PUBLIC(台舟电子)的完整数据手册与认证文件(RoHS、可靠性测试报告等),并确认包装形式与批次跟踪编号。常见标识为 SS14HE + 厂家标记 + 封装代码(具体视生产批次而定)。

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.
