SS56L(CJ/长晶)60V 5A 肖特基二极管 — 产品概述

一、产品简介

SS56L 是江苏长电(长晶)供应的一款低正向压降、高浪涌能力的肖特基整流二极管,封装为 SMAG,额定直流整流电流为 5A,反向耐压 60V。典型工作场景为电源整流、续流保护、反接保护及开关电源中的快速整流器件。

二、主要电气参数

  • 正向压降(Vf):约 500mV @ 5A(典型值)
  • 额定直流整流电流:5A
  • 直流反向耐压(Vr):60V
  • 反向电流(Ir):300µA @ 60V(随结温上升会显著增大)
  • 非重复峰值浪涌电流(Ifsm):120A(单次冲击、瞬态能力)
  • 工作结温范围:-55℃ ~ +150℃

以上参数为器件典型与额定值,具体电性能曲线请参考元件数据手册。

三、性能特点与优势

  • 低正向压降:500mV 左右的 Vf 能有效降低整流损耗,提升效率,尤其在低压大电流场合更显著。
  • 快速恢复/无恢复特性:肖特基结构使得开关速度快,适合高频开关电源与开关管并联的续流路径。
  • 高浪涌能力:Ifsm 达 120A,可承受启动、电容充放电等瞬态冲击(须遵循非重复峰值定义和脉宽限制)。
  • 宽工作温度:-55℃~+150℃ 的结温范围,利于工业级与高温环境应用。

四、应用场景

  • 开关电源(SMPS)和开关整流器的输出整流与续流二极管
  • 电池充放电路径、反向电压保护(反接保护)
  • DC-DC 转换器、车载电子(需注意耐压与温度升高下漏电)
  • 电机驱动、功率管理、太阳能逆变器的辅助整流

五、设计注意事项

  • 漏电随温度上升:Ir = 300µA@60V 在高温下会显著增加,若应用在高结温或高阻回路(如电池管理)需评估漏电影响。
  • 散热与热迁移:SMAG 封装散热能力有限,高电流连续工作时应做好 PCB 散热(加大铜箔、热孔、或外加散热片),以控制结温并保证长期可靠性。
  • 浪涌规范:Ifsm 为非重复峰值,请参考脉宽和重复率限制,勿在额定条件外反复施加大浪涌以免缩短寿命。
  • 焊接与回流工艺:遵守厂家推荐的回流曲线与预热要求,避免过高温度和过长时间引起封装应力或焊点问题。

六、封装与物理参数

  • 封装:SMAG(表面贴装),适用于自动贴装与回流焊流程。
  • 封装的热阻与引脚布局会影响散热效率,设计 PCB 时应参考厂家给出的推荐焊盘尺寸和热通孔布局。

七、采购与可靠性建议

  • 选型时确认来源为 CJ(江苏长电/长晶)原厂或授权代理,避免使用散装或来源不明产品。
  • 对于关键应用,建议索取并核对器件数据手册(温度特性、最大额定值、曲线图)及可靠性测试报告。
  • 在高温或连续大电流场合,留有适当的电流与温度裕度,必要时并联器件或选用更大额定器件。

八、总结

SS56L(CJ)为一款适合中高频电源与大电流整流应用的 60V/5A 肖特基二极管,具备低 Vf、快速响应和较强瞬态浪涌承受能力。合理的热设计和温度管理是发挥其性能与保证寿命的关键。对于需低损耗、高效率整流的方案,SS56L 是性价比较高的选择。

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.

Replenishment inquiry Typical RFQ workflow
