XR6800B N沟道MOSFET产品概述

XR6800B是新锐半导体(XNRUSEMI)推出的一款双N沟道增强型MOSFET,专为低电压(≤30V)、中电流(≤4.5A)场景设计,具备低导通损耗、高开关速度、紧凑封装等核心优势,广泛适配便携电子、电源管理、小型驱动等领域的应用需求。

一、关键电性能参数解析

XR6800B的参数设计精准匹配中低功率场景,核心参数如下:

1. 电压与电流能力

  • 漏源击穿电压(Vdss):30V,满足5V、12V、24V等常见低压系统的安全工作要求,避免过压损坏;
  • 连续漏极电流(Id):4.5A,是持续可承载的最大漏极电流,峰值电流能力支持短时间过载(需结合热设计);
  • 阈值电压(Vgs(th)):1.5V,兼容3.3V、5V栅极驱动电路,无需额外升压驱动,降低系统设计复杂度。

2. 导通与开关特性

  • 导通电阻(RDS(on)):29mΩ(@Vgs=10V,Id=4A),同封装级别中属于低水平,显著减少导通损耗,提升电源转换效率;
  • 栅极电荷量(Qg):3nC(@Vgs=15V),低栅极电荷意味着更快的开关速度,适合高频应用(如开关频率≤1MHz的DC-DC);
  • 电容特性:输入电容Ciss=233pF、反向传输电容Crss=33pF(@Vgs=15V),低Crss进一步降低开关损耗,优化高频性能。

3. 功耗与温度范围

  • 耗散功率(Pd):1.25W,支持持续工作的最大功耗,结合封装散热能力满足中功率场景需求;
  • 工作温度范围:-55℃~+150℃,覆盖工业级温度要求,适应低温户外设备、高温密集PCB区域等恶劣环境。

二、封装与可靠性设计

XR6800B采用SOT-23-6L封装,具有以下特点:

  • 紧凑体积:尺寸接近常规SOT-23封装,节省PCB空间,适配智能手环、蓝牙耳机等小型化产品;
  • 双N沟道集成:6脚封装内置两个独立MOSFET,可简化双开关电路(如电池充放电保护、双向负载开关),减少元件数量和布线;
  • 高可靠性:耐高温封装材料配合宽温度范围,长期稳定工作,符合RoHS环保标准。

三、典型应用场景

XR6800B的参数优势使其适配多种中低功率应用:

  1. 便携电子:手机、平板、智能穿戴的电源管理(负载开关、电池保护);
  2. 小型DC-DC:5V/12V转3.3V/5V的降压电路,或低功率升压电路;
  3. 电池保护:单节/多节锂电池的充放电控制(双MOS管实现过充、过放保护);
  4. 小型驱动:玩具电机、小型风扇、微型泵的驱动(电流≤4.5A);
  5. 音频辅助:低功耗音频放大的电源开关、音量控制电路;
  6. 工业控制:小型传感器节点的电源管理、低电压信号开关。

四、产品核心优势总结

XR6800B在同类产品中具备明显竞争力:

  • 高效节能:低RDS(on)和低开关损耗,提升系统效率,延长电池续航;
  • 设计简化:双N沟道集成+低阈值电压,减少驱动电路和元件数量;
  • 场景适配广:宽温度范围+30V电压能力,覆盖消费电子、工业、便携领域;
  • 成本优化:紧凑封装+高集成度,降低PCB成本和组装成本。

XR6800B作为新锐半导体的中低功率MOSFET代表产品,平衡了性能、体积与成本,是各类低压中电流应用的理想选择。

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
