SB5100_AY_10001 产品概述

一、产品简介

SB5100_AY_10001 是强茂(PANJIT)系列的肖特基整流二极管,采用 DO-201AD 轴向封装,面向中等功率整流和保护应用。该器件在 5A 直流整流电流下具有较低的正向压降(Vf = 0.85V @ 5A),并提供高达 100V 的反向稳压能力,适合需要低压降、高效率和抗浪涌能力的电源应用。

二、主要电气参数

  • 正向压降:Vf = 0.85V @ IF = 5A(低压降有利于降低功耗与发热)
  • 直流整流电流:IF(AV) = 5A,适用于连续工作负载
  • 直流反向耐压:VRRM = 100V,能满足中压整流与反向电压防护需求
  • 非重复峰值浪涌电流:IFSM = 150A,能承受开机或突发电流冲击
  • 工作结温范围:-50℃ ~ +125℃,适应较严苛的温度环境
  • 反向电流(Ir):用户给出值为“150A”,该数值显然不合理。肖特基二极管的反向漏电通常为μA 到 mA 级,且随温度快速上升。请务必以厂商正式数据手册为准以确认 Ir 在不同温度及 Vr 下的具体数值。

三、优势特性

  • 低正向压降:在高电流条件下减少功耗与热损耗,提高整流效率。
  • 快速恢复/固有低反向恢复:肖特基结构使其在高频开关场合具有更低的开关损耗。
  • 良好浪涌承受力:150A 峰值浪涌能力适合电源启动和瞬态冲击场景。
  • 宽温度范围:适合消费电子、通信设备及工业控制等环境变化较大的应用。

四、封装与热管理

DO-201AD 为轴向玻璃/树脂封装,机械强度好,便于手工焊接和波峰/选择性波峰组装。在 5A 级别持续工作时,器件的结温会随环境温度和散热状况上升,建议:

  • 在允许的安装空间内尽量保证空气对流,或在必要时配套散热片/散热带。
  • 注意引脚与安装板的热阻,良好的焊盘和导热路径有助于降低结温。
  • 在高温环境下关注反向漏电随温度增长的影响(可能显著增加)。

五、应用场景

适合用于 开关电源(输出整流)、输入整流、防反接保护、二极管 OR-ing、功率管理模块、汽车电子(在满足温度与浪涌要求时)以及各类需要中等功率整流与低压降的电源系统。

六、选型与使用建议

  • 确认反向漏电(Ir)随温度和电压的实际曲线,特别是高温场合对漏电敏感的应用需谨慎。
  • 若需要更低正向压降或更高电流承载,考虑并联多只或选用更大封装/更低 Vf 的型号,但要注意电流均分问题。
  • 在高频开关输出整流场合,评估肖特基的寄生电容与热性能是否满足系统需求。
  • 采购时以 PANJIT 官方数据手册或样片测量为准,避免仅凭片面数据做最终设计决策。

七、小结

SB5100_AY_10001 是一款针对中等功率整流与保护场景优化的肖特基二极管,具备较低正向压降、良好的浪涌承受能力与宽工作温度范围。使用前请核实厂方完整数据手册中关于反向漏电、热阻及典型曲线的详细说明,以确保在目标应用中获得可靠、稳定的表现。

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
