CR7N65A4K 产品概述

一、主要规格

CR7N65A4K 是华润微(CRMICRO)推出的一款高压 N 沟道功率 MOSFET,适用于中高压开关应用。主要参数如下:

  • 类型:N 沟道 MOSFET(单只)
  • 漏源电压 Vdss:650 V
  • 连续漏极电流 Id:7 A
  • 导通电阻 RDS(on):1.4 Ω @ Vgs=10 V
  • 耗散功率 Pd:108 W(注:实际热限受封装与 PCB 散热条件影响)
  • 阈值电压 Vgs(th):4 V @ Id=250 µA
  • 总栅极电荷 Qg:24 nC @ Vgs=10 V
  • 输入电容 Ciss:1.08 nF
  • 输出电容 Coss:75 pF
  • 反向传输电容 Crss(Coss 协调):3.2 pF
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:TO-252(DPAK)

二、产品特点

  • 650V 高耐压设计,适合离线开关与高压转换场合。
  • 中等导通电阻与较高承受功率能力,兼顾开关损耗与导通损耗的平衡。
  • 总栅极电荷 Qg=24nC,便于配合常见的驱动器实现较快切换,同时对驱动器要求适中。
  • 宽工作温度范围,适应工业级环境。

三、典型应用场景

  • 开关电源(SMPS)高压侧开关(反激、正激、半桥等)。
  • 输入 PFC 电路与高压 LED 驱动。
  • 工业电源与适配器中的高压开关。
  • 小功率逆变器和电机驱动的高压环节(需配合合适并联或并用器件)。

四、设计与驱动建议

  • 驱动电压:器件在 Vgs=10V 条件下性能标定,建议采用 10V 门极驱动以确保低 RDS(on);该器件非逻辑电平类型,4V 的阈值仅指导通起始。
  • 驱动能力:Qg=24nC,若要求快速变换(几十纳秒至百纳秒级),驱动器需能提供瞬时电流峰值(I = Qg / dt)。例如期望 100ns 切换时间时,驱动器峰值约为 0.24 A。
  • 栅极电阻:为抑制振铃并控制开关过渡,建议在 5–100 Ω 范围内选取合适栅极电阻,视开关速度和 EMI 要求调整。
  • 开关过冲保护:在具有感性负载或含寄生电感的电路中,建议采用 TVS、RC 吸收或漏感箝位等保护措施以防止 Vds 峰值超过额定值。
  • 注意查看并遵守器件的最大 Vgs 许可值与动态极限(请参见完整数据手册)。

五、热管理与可靠性

  • 标称耗散功率 Pd=108W 表明器件在良好散热条件下能力较强,但 TO-252 封装的实际热阻依赖于 PCB 铜箔面积、过孔与散热措施。建议在 PCB 设计中增加散热铜箔和过孔,必要时采用散热片或并联方案。
  • 在高温或高频工作条件下,要按厂方曲线进行功率与电流谱的降额设计,保证长期可靠性。
  • 推荐在评估中包含热仿真和实际测温验证。

六、封装与采购信息

  • 封装形式:TO-252(DPAK),适合表面贴装与中功率板级散热。
  • 品牌:CRMICRO(华润微)。
  • 购买与替代:在采购与替代器件时,请以完整数据手册为准,核对电气特性、最大额定值与封装引脚定义。

总结:CR7N65A4K 为一款面向中高压开关应用的可靠 N 沟道 MOSFET,具有较高的耐压和适中的开关性能。合理的驱动设计与良好的 PCB 散热布局,是发挥其性能并保证可靠性的关键。若需详细动态特性、SOA、脉冲承受能力与封装热阻等完整信息,请参考厂方数据手册或联系供应商技术支持。

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
