CR4N65FA9K 产品概述

一、产品简介

CR4N65FA9K 是华润微(CRMICRO)出品的一款高耐压 N 沟道功率场效应管(MOSFET),封装为 TO-220F,单片结构(数量:1 个 N 沟道)。器件适用于需要 650V 耐压能力且中等电流/中等开关速度的电源与功率转换场合,工作温度范围为 -55℃ 至 +150℃。

二、主要参数与性能亮点

  • 漏源电压 Vdss:650V,适合高压边开关和离线电源应用。
  • 连续漏极电流 Id:4A,适合中等电流工况。
  • 导通电阻 RDS(on):2.8Ω @ Vgs=10V,器件导通损耗在高压应用中属于可接受范围,但不适合对导通损耗要求极低的低压大电流场合。
  • 阈值电压 Vgs(th):4V @ 250µA,仅作导通起始参考,实际工作应采用 10V 驱动以满足标称 RDS(on)。
  • 总栅极电荷 Qg:15.8nC @ 10V,驱动能量中等,要求门极驱动器具备相应电流能力以获得所需开/关速度。
  • 输入/输出/反向电容:Ciss=564pF、Coss=41pF、Crss=2.4pF,表明器件具备中等输入电容与较小的米勒电容,有利于减小米勒效应对开关过渡的影响。

三、封装与热性能

  • 封装:TO-220F(绝缘型),便于安装散热片和PCB布局。
  • 耗散功率 Pd:30W(额定值),实际可用散热能力依赖于系统的散热器、空气流动和焊接/安装方式。在高功率或连续工作场景下,建议配备合适散热片并评估结-环境热阻以保证结温在安全范围内。

四、典型应用场景

  • 离线开关电源(小功率反激/正激前端)与电源保护电路。
  • LED 驱动与照明电源中的高压开关元件。
  • 工业电源、适配器以及需要高耐压但电流需求不大的功率转换模块。
  • 作为高压侧开关或备用保护器件使用。

五、设计及选型建议

  • 驱动电压:尽量采用 Vgs≈10V 驱动以实现标称 RDS(on)。阈值电压 4V 仅表示导通临界,不宜作为工作驱动点。
  • 门极驱动器选型:Qg=15.8nC 表明栅极驱动需提供较高脉冲电流以快速充放电,若追求更快开关需相应增加驱动能力,否则会加大发热与开关损耗。
  • 导通损耗考虑:RDS(on) 为 2.8Ω,导通损耗较大,应在系统中评估平均电流与占空比,必要时采用并联或选用低 RDS(on) 器件替代。
  • 开关损耗与应力管理:Coss 与 Crss 值有利于降低米勒相关的开关抖动,但在高频运行时依然需关注开关损耗与电磁兼容(EMI)。

六、可靠性与使用注意事项

  • 工作环境:器件可在 -55℃ 至 +150℃ 环境下使用,但长期可靠性依赖于结温管理,建议在设计中留出热裕度。
  • 反复冲击与浪涌:作为高压器件,在系统设计中应做好浪涌吸收与过压保护,避免超出 Vdss 和功耗极限。
  • PCB 布局:高压及高 dV/dt 场合注意保持爬电距离和合理接地,门极回路应尽量短以降低寄生电感。

七、总结

CR4N65FA9K 是一款面向高压场合的单片 N 沟道 MOSFET,具有 650V 耐压、4A 连续电流能力和 30W 额定耗散。器件适合用于离线电源与高压开关场景,需配合 10V 门极驱动及良好散热方案以获得可靠工作。选型时需综合考虑 RDS(on) 带来的导通损耗与栅极电荷对驱动器的要求,确保在目标应用中达到预期的效率与可靠性。

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.
