SS110 肖特基二极管(850mV@1A,100V,SMA 封装)产品概述

一、产品概述

SS110 为 BORN(伯恩半导体)推出的一款通用肖特基整流二极管,适用于中低功率整流与保护场合。其在 1A 工作电流下的典型正向压降约为 850mV,反向耐压 100V,单颗器件采用 SMA(DO-214AC)封装,适配自动贴片与常见 PCB 布局。该器件兼顾低正向损耗与较高的浪涌能力,适合开关电源、DC–DC 转换、电池保护与整流等应用。

二、主要参数

  • 正向压降 (Vf):850mV @ IF = 1A(典型条件)
  • 直流反向耐压 (Vr):100V
  • 最大平均整流电流:1A
  • 反向电流 (Ir):500μA @ Vr = 100V
  • 非重复峰值浪涌电流 (Ifsm):40A(单次脉冲)
  • 工作结温范围:-65°C ~ +150°C
  • 封装:SMA(DO-214AC)

三、产品特点

  • 低正向压降:在 1A 工作点上 Vf 约 850mV,降低整流损耗,有利于提高效率和降低发热。
  • 肖特基特性:开关速度快、正反向恢复损耗小,适合高频整流与开关应用。
  • 良好的浪涌能力:40A 的单脉冲浪涌能力可应对短时启动或浪涌电流。
  • 紧凑封装:SMA 封装兼顾散热与空间占用,适用于自动化贴装生产。

四、典型应用

  • 开关电源整流与辅道二极管
  • DC–DC 转换器的自由轮回或续流二极管
  • 蓄电池和电源的反接/反向保护
  • LED 驱动、电机驱动电路中的保护与整流
  • 通用整流、耗散功率受控的稳压/电源模块

五、设计与使用建议

  • 热设计:尽管 SMA 封装体积小,但工作电流 1A 时仍需在 PCB 上预留较大铜箔面积与散热通路,必要时采用多层铜层与热沉或通孔散热。
  • 结温管理:在高温或高负载环境下注意对平均电流的降额使用,避免长期在最大额定电流下工作。
  • 焊接工艺:支持常规回流焊工艺,建议按 PCB 制造与元件供应商的回流曲线执行以避免过热或机械应力。
  • 封装识别:SMA 外观有极性标记(通常为环带表示阴极),焊接时注意方向以防反接损坏。

六、可靠性与注意事项

  • 反向漏电:在高耐压(接近 100V)且高温条件下反向漏电会显著增加,长时间高温高压会加速漏电增长,设计时应考虑裕量。
  • 浪涌能力与重复性:40A 的 Ifsm 仅适用于非重复短脉冲(例如半波整流的充电浪涌),对重复脉冲或长脉冲需做热仿真和降额。
  • 存储与工作环境:器件工作结温范围宽(-65°C 至 +150°C),但在极端环境下仍需考虑封装机械可靠性与 PCB 应力。

七、选型建议

在需要在体积受限同时追求低正向压降与快速开关的场合,SS110 是性价比较高的选择。若应用对漏电流要求更严格或需更低 Vf,可考虑更高等级的肖特基器件;若浪涌或平均电流要求更高,则应选用更大封装或并联多颗器件并做好热管理。

八、典型电路参考

  • 反向保护:将 SS110 串联在电源输入端的正线或负线,利用肖特基低 Vf 实现低损耗的反向保护。
  • 自由轮回:在降压转换器功率开关并联作为续流二极管,利用其快速恢复特性降低开关损耗。

总结:BORN 的 SS110 在 SMA 封装中提供了 100V 耐压、1A 连续整流与较低正向压降的平衡性能,适合多种中低功率整流与保护应用,关键在于合理的 PCB 散热设计与对反向漏电和浪涌条件的评估。若需更详细的电气特性曲线与封装尺寸图,请参考厂商完整数据手册。

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.
