SS0520_R1_00001 产品概述

一、产品简介

SS0520_R1_00001 是强茂(PANJIT)推出的一款低压肖特基整流二极管,采用 SOD-123 表面贴装封装,面向空间受限且要求低正向压降与快速开关的应用场景。该器件典型工作结温范围为 -55℃ 至 +125℃,在额定整流电流 500mA 条件下,表现出极低的正向压降与良好的浪涌承受能力,适合移动设备电源管理与低压电源路径保护。

二、主要规格与电气性能

  • 额定整流电流(IF):500 mA(连续)
  • 正向压降(Vf):典型 385 mV @ 500 mA(低 Vf 有助于降低导通损耗)
  • 直流反向耐压(VR):20 V(适用于低压电源轨)
  • 反向漏电流(IR):75 µA @ 10 V(注意随温度上升显著增加)
  • 非重复峰值浪涌电流(Ifsm):5.5 A(短时充电/浪涌吸收能力)
  • 工作结温:-55℃ ~ +125℃

正向导通损耗举例:在 500 mA 条件下,P = Vf × I ≈ 0.385 V × 0.5 A ≈ 0.1925 W,表示在合理散热的 PCB 设计下功耗较小,适合高效率需求的应用。

三、封装与热特性

SOD-123 为低剖面、小外形 SMD 封装,适合自动贴装生产,便于在紧凑电路板上部署。由于封装体积与铜箔散热面积有限,连续工作电流 500 mA 在高环境温度或受限散热情况下需进行热管理与降额处理。建议在 PCB 走线处增加热沉铜箔面积、添加过孔或与散热平面连接,以降低结温并延长器件寿命。

四、典型应用场景

  • 低压开关电源的输出整流与同步整流备选
  • 电源反向保护、反接保护二极管(电源 OR’ing)
  • 移动设备与便携式产品的电源路径选择
  • LED 驱动(低电压、低电流场景)与浪涌抑制
  • EMI/ESD 保护和快速恢复整流场合

五、选型注意事项与使用建议

  1. 漏电流依赖温度:75 µA @ 10 V 为室温参考值,工作温度升高时 IR 会成倍上升,若系统对待机功耗或漏电敏感,应选用更低 IR 的型号或采取热隔离。
  2. 浪涌规格求证:Ifsm 为非重复峰值能力,具体脉冲宽度与重复频率会影响器件承受能力,设计时应参照厂方完整数据手册确认脉冲条件。
  3. 热降额:在高环境温度或狭小 PCB 热阻下,应对 500 mA 连续电流进行降额,或通过增加铜箔面积和散热路径改善散热。
  4. 焊接工艺:按 SOD-123 的回流焊工艺规范执行,避免超温与过长保温时间,焊接后建议进行外观与电性能抽检。

六、可靠性与测试建议

  • 建议在样机阶段进行温升测试(不同负载与不同铜箔面积),确认结温不过高。
  • 对关心漏电流的应用进行高温漏电测试(例如 85℃、100℃)以验证实际工作下的 IR。
  • 在有浪涌或充电电容的场景下,进行多次充放电冲击测试以验证 Ifsm 在实际脉冲下的可靠性。

七、总结

SS0520_R1_00001 以其低正向压降(385 mV @ 500 mA)、适中的 20 V 反向耐压和 5.5 A 的瞬态浪涌承受能力,适合要求低损耗、快速整流的低压电源与保护场合。基于 SOD-123 封装,它适用于体积受限的消费电子与工业类产品。选型时重点关注工作温度下的漏电流和热管理方案,必要时参考强茂提供的完整数据手册以获取详细脉冲与热参数。

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.
