SS24-SMB(GOODWORK固得沃克)肖特基二极管产品概述

一、产品基本属性

SS24-SMB是GOODWORK(固得沃克)品牌推出的独立式肖特基整流二极管,采用SMB封装(对应国际标准DO-214AA),属于表面贴装型器件。型号命名中,“SS”明确肖特基二极管(Schottky Diode)属性,“24”对应2A平均整流电流与40V直流反向耐压,“SMB”为封装形式标识,产品核心属性清晰可辨。

二、核心电气性能参数

SS24-SMB围绕低压高效、抗冲击能力优化,关键参数如下:

  • 正向压降(Vf):典型值550mV@2A(导通电流2A时的电压降),远低于普通硅二极管(约700mV以上),可显著降低导通损耗;
  • 直流反向耐压(Vr):额定值40V,适配12V、24V等低压直流系统;
  • 平均整流电流(Io):2A,可稳定承载中功率负载电流;
  • 反向漏电流(Ir):典型值100uA(额定反向电压下),漏电流小,待机功耗低;
  • 非重复峰值浪涌电流(Ifsm):50A(8.3ms正弦波脉冲),具备较强的瞬间过流抗冲击能力;
  • 工作结温范围:-65℃~+150℃,覆盖极端高低温环境,适应工业、户外等场景。

三、封装与物理特性

SS24-SMB采用SMB(DO-214AA)表面贴装封装,具有以下特点:

  1. 体积紧凑:尺寸约3.5mm×2.7mm×1.5mm,适合高密度PCB布局,可有效节省电路空间;
  2. 贴装便捷:符合SMT自动化生产要求,引脚间距适配标准贴片机,生产效率高;
  3. 极性识别:封装表面带有阴极标记(如白色/黑色条纹),便于安装时正确识别极性,避免反向损坏;
  4. 散热适配:封装热阻较低,配合PCB铜箔可有效导出导通损耗产生的热量,保障长期稳定工作。

四、典型应用场景

结合性能参数,SS24-SMB主要应用于以下低压中功率场景:

  1. 开关电源模块:12V/24V DC-DC转换器的输出整流,低Vf可提升转换效率(相比普通二极管约5%~10%);
  2. 续流二极管:电机驱动、电感负载电路中的续流保护,低压降减少续流功耗与发热;
  3. 反向保护电路:智能家居、便携式仪器的电池反向过流保护,40V耐压覆盖多数低压电池系统;
  4. LED驱动电路:小功率LED串的整流/续流,与LED正向压降匹配,优化驱动效率;
  5. 工业控制设备:PLC、传感器模块的电源整流,宽结温范围适应车间高低温环境。

五、产品优势与应用价值

SS24-SMB在同类器件中具备明显优势:

  1. 高效节能:低正向压降直接降低导通损耗,减少电路发热,延长器件与周边元件寿命;
  2. 高可靠性:50A浪涌能力与宽结温范围,可应对启动、负载突变等瞬间冲击,提升系统稳定性;
  3. 设计灵活:小体积SMB封装适配高密度PCB,适合智能穿戴、物联网终端等小型化设备;
  4. 成本可控:固得沃克品牌的性价比优势,在保障性能的前提下降低BOM成本。

六、选型与使用注意事项

  1. 选型匹配:确认应用场景的最大反向电压≤40V、平均电流≤2A,避免超参数使用;
  2. 极性安装:严格按照封装标记识别阴极(带标记端为阴极),反向安装会导致器件损坏;
  3. 散热设计:2A电流下建议PCB预留≥3mm×3mm铜箔面积,避免结温超过150℃;
  4. ESD防护:肖特基二极管对静电敏感,生产/存储需采用防静电包装与操作,避免静电损伤。

综上,SS24-SMB是一款专为低压中功率场景优化的高性价比肖特基二极管,凭借低损耗、高可靠性与紧凑封装,广泛适用于消费电子、工业控制、电源模块等领域。

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
