SP860L 产品概述

一、产品简介

SP860L 为一颗独立式肖特基二极管,由 DOWO(东沃)出品,封装为 TO-277B。肖特基结构带来低正向压降与快速恢复特性,适合高效率电源和开关应用。该器件设计用于中等电流整流与冲击耐受场合,兼顾散热与抗浪涌能力。

二、主要参数与性能

  • 正向压降 (Vf):≈0.53 V(厂方标称值,实际 Vf 与测试电流和结温有关,请以样片数据为准)
  • 直流反向耐压 (Vr):60 V
  • 连续整流电流:8 A
  • 反向漏电流 (Ir):150 μA @ 60 V(常温条件下测得)
  • 非重复峰值浪涌电流 (Ifsm):180 A
  • 工作结温范围:-55 ℃ ~ +150 ℃
    这些参数表明器件在常温下有较低的导通损耗与良好浪涌承受能力,但反向漏电随温度上升会增加,热管理需重视。

三、典型应用场景

  • 开关电源输出整流(Synchronous 替代或混合场景)
  • 续流/自由轮二极管(电感负载回路)
  • 防反接保护与低压降电源路径
  • 电池管理与充电器(需注意温升与漏电)
  • 工业电源模块与功率整流单元

四、设计与热管理注意事项

  • Vf 标称值通常在特定电流(如 4 A、8 A)下测得,设计时应按目标工作电流和最高结温计算功耗 P = Vf × I。
  • TO-277B 封装需充分散热:建议配合散热片或把器件固定在具良好导热性的机械结构上,以保证长期 8 A 连续工作。
  • 反向漏电随温度显著上升,高温环境下需考虑漏电对系统待机功耗和失效安全的影响。
  • Ifsm 表示非重复峰值浪涌能力,适用于启动或短时冲击,但不宜作为连续过载依据。

五、封装与机械特性

TO-277B 提供便于装配的螺栓固定方式,利于与散热片直接接触并实现可靠热路径。实际安装时应注意绝缘需求和螺钉扭矩,避免应力集中或降额。

六、可靠性与环境适应

器件额定结温范围为 -55 ℃ ~ +150 ℃,适应较宽温度环境。长期可靠性受结温与循环温度影响,建议在高温、高应力场合进行加速寿命评估。

七、选型建议

在替代或比较时,关注三项关键指标:Vf(导通损耗)、Ir(漏电)与 Ifsm(浪涌能力),并结合封装热阻与实际散热方案进行整机级热仿真。若需满足更低 Vf 或更高 Vr/Ifsm,可在同类肖特基产品中对比 SPEC 表进行选择。

备注:以上为基于您提供参数的产品概述,建议在最终设计前查阅厂方完整 datasheet 并做样品验证,以确保关键工况下的性能与可靠性。

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
