SS34FL 产品概述

一、产品简介

SS34FL 为 SHIKUES(时科)系列独立式肖特基二极管,采用 SMAF 封装,面向中功率整流与保护应用。该器件额定整流电流为 3A,直流反向耐压(Vr)40V,正向压降低,规格为 450mV @ 3A;非重复峰值浪涌电流(Ifsm)可达 80A。工作结温范围宽,-55℃ 至 +125℃,适用于工业、通信与消费类电子设备。

二、主要特性

  • 低正向压降:典型 Vf = 0.45V(3A),有助于减少整流损耗与系统发热。
  • 可靠的浪涌能力:Ifsm = 80A(非重复峰值),能承受短时冲击负载。
  • 宽工作温度:-55℃~+125℃,适应严苛环境。
  • 紧凑封装:SMAF 小体积,便于 PCB 布局与高密度设计。
  • 独立式配置:便于单独更换与分区保护设计。

三、典型应用

  • 开关电源(输出整流、同步整流替代)
  • DC-DC 转换器与电源管理模块
  • 反向极性保护与续流二极管
  • 汽车电子(非高压主电路)、通信设备、工业控制系统
  • 电池充放电保护与功率路径选择

四、封装与散热建议

SMAF 封装体积较小,热阻相对较大,设计时建议:

  • 在 PCB 上使用加宽的焊盘和厚铜接地层以提升散热能力;
  • 如果长期 3A 工作,应评估功耗(P = Vf × I)并保证结温在允许范围内;
  • 对于高频整流或高占空比场合,注意热循环与焊点可靠性。

五、选型与使用注意

  • 若系统要求更低正向压降或更高电流,应考虑并联多只或选用更大封装器件;并联时需注意电流均流问题。
  • 在高温或连续大电流条件下,应进行实际结温测量以防热失效。
  • 对于敏感电路,建议在输入端增加合适的抑制与滤波措施,防止浪涌或反向尖峰损伤器件。

总结:SS34FL(SHIKUES 时科)为一款面向中功率整流与保护的肖特基二极管,低 Vf 与良好的浪涌能力使其在开关电源、功率路径保护及一般整流场景中具有良好性价比。选型时应结合系统散热与工作环境做热设计验证。

Sourcing availability signal

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
