XR80N03B 产品概述

一、产品简介

XR80N03B 是一款高单元密度的沟槽式 N 沟道功率 MOSFET,采用 TO252-3L 封装,专为同步降压转换器和各类高效率开关电源设计而优化。器件在低导通电阻与适中栅极电荷之间实现良好平衡,适合需要低导通损耗且驱动能力有限的应用场景。产品符合 RoHS 与绿色环保要求,并做 100% 雪崩耐量测试,具备完整的功能与可靠性保证。

二、主要规格(关键参数)

  • 器件类型:N 沟道功率 MOSFET(沟槽式)
  • 数量:单个(1 个 N 沟道)
  • 漏-源最大耐压 Vdss:30 V
  • 连续漏极电流 Id:80 A
  • 导通电阻 RDS(on):4 mΩ(Vgs = 10 V)
  • 功耗 Pd:42 W
  • 阈值电压 Vgs(th):1.5 V(典型或门限参考)
  • 总栅极电荷 Qg:33.7 nC(测量条件 Vgs = 15 V)
  • 输入电容 Ciss:1.614 nF
  • 反向传输电容 Crss(米勒电容):215 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 包装:TO252-3L(DPAK 类似封装)
  • 可靠性:100% 雪崩耐量测试;符合 RoHS

三、关键特性与优势

  • 低导通电阻:4 mΩ(10 V 驱动)在高电流条件下能显著降低导通损耗,适合高效率苛刻场合。
  • 合理的栅极电荷:Qg = 33.7 nC(15 V)在快速开关时可保持较低的驱动能耗,便于与常见驱动器或 MCU 驱动电路匹配。
  • 小型功率封装:TO252-3L 在保持良好散热性能的同时便于表面贴装(SMT)组装,适合中高密度 PCB 布局。
  • 工艺可靠:沟槽结构带来更优的 Rds(on) 与栅极电容特性组合;100% 雪崩测试提升抗浪涌与可靠性能力。
  • 宽工作温度:可在-55 ℃ 至 +150 ℃ 环境使用,适应工业级温度需求。

四、典型应用场景

  • 同步降压转换器(同步整流开关管)
  • 开关电源(SMPS)与点对点电源管理
  • 电机驱动的低侧开关或半桥拓扑
  • 负载开关、功率分配与电源保护电路
  • UPS、太阳能逆变器的局部功率级(在额定电压和电流范围内)

五、驱动与开关特性建议

  • 栅极驱动电压:为获得标称 RDS(on),建议采用 10 V 驱动。若驱动电压受限(例如 5 V),应评估实际 Rds(on) 与导通损耗变化。
  • 栅极驱动能力:Qg 为 33.7 nC,驱动器应能提供足够的电流以满足目标开关速度,避免过慢导致开关损耗增加,亦要避免过快造成过高的瞬态电流和 EMI。
  • 开关损耗考量:Crss(215 pF)影响米勒效应和过渡期间的能耗。在高频切换应用中,需在开关布局与缓冲措施(如 RC 缓冲)上权衡,避免因米勒电容引起的误导通或振铃。
  • 布局建议:将高电流路径(漏-源)短且粗,接地回路尽量靠近器件引脚,栅极驱动回路短且屏蔽以减少寄生电感。

六、热设计与可靠性提示

  • TO252-3L 封装散热依赖 PCB 铜箔与过孔布局,建议在 PCB 底层设计足够的散热铜面积与多层过孔热通道,以保证在连续 80 A 电流水平下的温升受控。
  • 器件额定功耗 Pd = 42 W,但实际可允许的功耗受 PCB 散热与环境条件限制,应通过热仿真或实验验证在目标工况下结温(Tj)与寿命裕度。
  • 100% 雪崩耐量测试提升了抗浪涌能力,但不等同于无限次承受高能量冲击。系统设计仍需在能量约束下配置必要的保护电路(如 TVS、限流、电感缓冲等)。

七、选型与替代注意事项

  • 在选择替代型号时,需重点匹配 Vdss、Id、Rds(on)(在同一 Vgs 条件下)、Qg 与封装散热特性,确保在目标频率与电流下整体损耗与散热可控。
  • 若系统受限于驱动电压或需更低的栅极电荷,可考虑同类参数下更低 Qg 或更适合 5 V 驱动的器件。

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.
