SS510 肖特基二极管(FOSAN)产品概述

一、产品简介

SS510 是 FOSAN(富信)出品的一款独立式肖特基整流二极管,采用 SMA 封装(常见为 DO‑214AC 封装形式)。该器件面向中高压中大电流整流场合,设计用于提高开关效率、降低导通损耗并具备良好的浪涌承受能力,适合开关电源、整流桥、续流保护及反接保护等应用。

二、主要电气参数

  • 二极管数量:1 个独立式
  • 正向压降(Vf):0.85 V @ 5 A
  • 直流反向耐压(Vr):100 V
  • 额定整流电流(If):5 A(DC)
  • 反向漏电流(Ir):20 μA @ 100 V
  • 非重复峰值浪涌电流(Ifsm):120 A(单次、冲击)
  • 工作结温范围:-65 ℃ 至 +150 ℃
  • 封装:SMA

三、特性与优势

  • 低导通压降:在 5 A 条件下 Vf 为 0.85 V,相比一般普通整流二极管有更低的导通损耗,有利于提高效率并降低发热。
  • 宽温度范围:-65 ℃ 至 +150 ℃ 的工作结温,使器件适应性强,能够承受较恶劣的工作环境。
  • 优良的浪涌能力:120 A 的非重复峰值浪涌电流可以应对瞬态冲击,适合启动或短时过载场合。
  • 小封装、高密度应用:SMA 封装便于表面贴装(SMT)应用,有利于设备小型化和自动化生产。

四、热管理与封装说明

SMA 封装体积小,热阻相对较高,实际使用中应重视散热设计:

  • PCB 上建议增加散热铜箔、加大焊盘面积并采用热过孔(thermal vias)将热量导至背面大铜层。
  • 在高平均电流或高占空比应用中,应进行结温计算并适当降额使用,避免长期在接近最高结温下工作。
  • 浪涌与短时大电流虽可承受,但频繁冲击会缩短寿命,应配合软启动或限流措施。

五、典型应用场景

  • 开关电源二次整流与续流回路
  • 充电电源与适配器输出整流
  • 反向接入保护、二极管 ORing 电路
  • 功率模块的续流、钳位与钳位保护场合

六、PCB 布局与焊接建议

  • 焊盘设计遵循厂商推荐图样以保证热传导与可靠焊接;若无详细图样,可适当增大铜箔面积。
  • 回流焊时控制温度坡度,避免过高预热和焊接峰值温度对器件产生热应力。
  • 对于高电流路径,减少走线阻抗并使用多层铜箔或加厚铜层改善热流和电流承载能力。

七、可靠性与注意事项

  • 反向漏电流会随温度上升而增加,若在高温及高压同时工作的场合需评估漏电影响。
  • 非重复峰值浪涌为单次冲击指标,频繁浪涌会损害器件;应在电路设计中采用限流或浪涌抑制元件。
  • 保持无静电、防潮和常规储运条件,避免机械应力损伤引脚或封装。

八、订购信息与替代选择

  • 品牌:FOSAN(富信)
  • 型号:SS510,封装 SMA,额定 5 A / 100 V。
  • 选型时如需更低 Vf 或更高耐压,可以在同类肖特基家族中对比不同型号;若需要更高浪涌能力或更低热阻,考虑更大封装(如 DO‑214AA、TO‑220 类)或并联多只器件并做热电匹配。

如需基于具体工作条件(电流波形、占空比、结温目标)做退载计算或 PCB 焊盘推荐图,请提供电路参数与工况,我可以给出更精确的设计建议。

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
