SS56F 肖特基二极管(GOODWORK 固得沃克)产品概述

一、产品简介

SS56F 为 GOODWORK(固得沃克)推出的一款独立式肖特基整流二极管,封装为 SMAF。该器件在额定整流电流 5A 条件下具有典型正向压降 0.7V(Vf@5A),反向耐压(Vr)为 60V,反向漏电流小于 100µA,非重复峰值浪涌电流(Ifsm)可达 120A,工作结温范围宽,-65℃ 至 +150℃,适用于中低压、高效率整流与保护场合。

二、核心特性

  1. 低正向压降:Vf≈0.7V@5A,降低导通损耗,有助于提升系统效率并减小散热负担。
  2. 中等电压等级:Vr=60V,适合大多数 12V、24V 及 48V 直流系统的整流与保护应用。
  3. 高整流能力:连续整流电流 5A,满足多数中功率电源与电机驱动需求。
  4. 强抗浪涌能力:Ifsm=120A(单次非重复峰值),可承受较大的启动或短路浪涌电流。
  5. 低漏电流:反向电流 ≤100µA(标称,随温度升高会上升),便于低功耗或待机场合使用。
  6. 宽温度范围:-65℃~+150℃,可靠性高,适应工业级温度环境。

三、典型应用场景

  • 开关电源及整流模块的输出整流和反向保护。
  • DC-DC 降压/升压转换器中的快速整流。
  • 输出 OR’ing(电源并联切换)、反向电流阻断和电池保护电路。
  • 电池充电、太阳能逆变器及工业控制设备。
  • 汽车电子中对中低压电源的整流与防逆接保护(需确认环境温度与规范要求)。

四、选型与设计注意事项

  • 功率与散热:尽管 Vf 较低,但在连续 5A 工作时仍会产生显著功率损耗(P=Vf×If),应在 PCB 上留足铜厚和散热面积,或采用强制散热措施以保证结温在允许范围内。
  • 漏电随温度变化:肖特基二极管的反向漏电随温度显著上升,若用于高温或高阻态检测电路需验证漏电对系统的影响。
  • 峰值浪涌能力:120A 的 Ifsm 仅适用于短时单次浪涌(例如整流器的浪涌),频繁或长时冲击需按热冲击与寿命评估。
  • 电压余量:如电路可能出现超过 60V 的尖峰或反向过压,应选用更高 Vr 的器件或增加浪涌抑制元件(TVS、RC 吸收等)。

五、封装与可靠性

SMAF 封装为独立式器件,便于点对点安装及替换。GOODWORK 提供工业级工艺与测试,器件适用于严苛温度循环与冲击环境。具体封装尺寸、引脚排列与焊接工艺请参照厂方数据手册,以保证安装可靠性与焊接质量。

六、使用与存储建议

  • 焊接时遵循推荐回流/波峰温度曲线,避免过高温度或长时间保温。
  • 存放于干燥、防静电环境,未使用的器件建议按原包装保存以防潮湿。
  • 安装过程中避免机械应力直接作用于封装体或引脚,影响长期可靠性。

总结:SS56F(GOODWORK)是一款面向中低压高效率整流与保护的肖特基二极管,凭借低 Vf、高 Ifsm 和宽温区特性,适合各类工业、消费及汽车电子应用。在设计时应重视散热布局与温度对漏电的影响,以发挥其最佳性能。若需更详细的电气特性曲线、封装图与推荐焊接参数,请参考厂方完整数据手册。

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
