XR4822A 产品概述

XR4822A 是 XNRUSEMI(新锐)推出的一款高性能互补 MOSFET 器件,内含一枚 N 沟道与一枚 P 沟道 MOSFET,封装为 SOP-8,专为同步降压转换器和高密度电源管理应用优化设计。器件在单元密度、导通电阻与栅极电荷之间取得良好平衡,满足对效率与开关性能的刚性需求,同时符合 RoHS 与绿色环保要求,并提供 100% 单脉冲雪崩能量保证,可靠性良好。

一、主要电气参数

  • 漏源电压 Vdss:30 V
  • 连续漏极电流 Id:9.5 A
  • 导通电阻 RDS(on):29 mΩ @ Vgs = 4.5 V
  • 阈值电压 Vgs(th):2.5 V
  • 总栅极电荷 Qg:10 nC @ 10 V
  • 输入电容 Ciss:490 pF
  • 输出电容 Coss:79 pF
  • 反向传输电容 Crss:61 pF
  • 功耗耗散 Pd:2.8 W
  • 工作温度范围:-55 ℃ ~ +150 ℃

二、产品亮点

  • 互补设计:同封装内包含 N 沟道与 P 沟道,便于在单双通道、同步整流或高侧/低侧组合中使用,节省 PCB 面积与器件数。
  • 低导通电阻:29 mΩ@4.5V,适合中小电流的低压开关场合,降低导通损耗,提高效率。
  • 合理的栅极电荷:Qg = 10 nC@10V,在开关频率较高时仍能兼顾驱动损耗与开关速度。
  • 完整的可靠性保证:符合 RoHS、绿色产品规范,并对单脉冲雪崩能量做 100% 保证,适合严苛环境下的可靠设计。

三、典型应用场景

  • 同步降压(Buck)转换器的高侧/低侧开关对
  • 手机、平板与便携式设备的电源管理模块
  • 服务器与通信设备的局部稳压器、点载电源(POL)
  • 电池管理与电源分配系统中需高集成与高密度的场合

四、设计与使用建议

  • 栅极驱动:若目标效率优先,推荐在 4.5 V 驱动条件下使用以实现标称 RDS(on)。若使用更高 Vgs,可获得更低导通电阻但需注意栅极电压容限。
  • 热管理:Pd = 2.8 W,封装热阻与 PCB 散热设计直接影响持续载流能力,高占空比或长时间大电流工况建议通过铜箔、散热垫片或散热设计来降低结温。
  • 开关损耗优化:关注 Qg、Coss 与 Crss,在高频应用中合理选择驱动器与开关频率,并优化 PCB 布局以减少寄生电感。
  • 并联注意:若为实现更低 RDS(on) 或更大电流并联多片器件时,应确保栅极驱动分布均衡,注意散热一致性与电流共享。

五、可靠性与封装说明

  • 封装:SOP-8,便于表面贴装加工与小体积布局。
  • 温度与可靠性:工作温度范围宽(-55~+150 ℃),适合工业级或更高温度环境。器件通过完整的功能可靠性保证,适合关键电源设计。

总结:XR4822A 在 30V 电压等级中提供了低导通电阻、适中栅极电荷与互补 N/P 的高度集成方案,特别适合要求体积小、效率高的同步降压与电源管理场合。根据具体功率与频率需求,结合合理的栅极驱动与散热设计,可显著提升系统性能与可靠性。

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
