IPD95R2K0P7ATMA1 产品概述 — Infineon(英飞凌)

一、产品简介

IPD95R2K0P7ATMA1 是英飞凌推出的一款高耐压 N 沟道功率 MOSFET,适用于需要高耐压与中等电流能力的开关应用。器件额定漏源电压高达 950V,单元为 1 个 N 沟道,封装为 TO-252(常见的 DPAK 表面贴装型),适合用于开关电源、离线转换器和功率因数校正等场合。

二、主要参数

  • 类型:N 沟道 MOSFET(增强型)
  • 漏源电压 Vdss:950 V
  • 连续漏极电流 Id:4 A
  • 导通电阻 RDS(on):2 Ω @ Vgs = 10 V
  • 栅极阈值电压 Vgs(th):3.5 V @ ID = 80 μA
  • 总栅极电荷 Qg:10 nC @ Vgs = 10 V
  • 输入电容 Ciss:330 pF
  • 输出电容 Coss:5 pF
  • 反向传输电容 Crss:81 pF @ 400 V
  • 功耗耗散 Pd:37 W(视散热条件而定)
  • 工作温度范围:-55 ℃ ~ +150 ℃

三、器件特点与优势

  • 高耐压能力:950V 的耐压使其特别适合高压开关应用,如离线开关电源、功率因数校正(PFC)级以及电力电子前端。
  • 中等电流承载:4A 连续电流适合中小功率转换器和开关拓扑,不同于低压大电流器件,更侧重耐压与开关特性平衡。
  • 合理的栅极电荷:10 nC 的总栅极电荷在 10V 驱动下属于中等水平,便于采用常见驱动器驱动且开关损耗可控。
  • 标准封装:TO-252 表面贴装封装利于自动化生产,具备良好的 PCB 散热布局可能性。

四、典型应用场景

  • 离线开关电源(SMPS)高压开关器件
  • 功率因数校正(PFC)前端(高压段)
  • LED 驱动与高压照明电源
  • 工业电源与电源适配器高压级
  • 需要高压耐受但中等电流的电子负载与保护电路

五、热设计与布局建议

  • 虽然器件额定耗散可达 37W,但实际功耗高度依赖 PCB 散热面积和环境条件。建议在 PCB 上为 TO-252 的散热引脚和底面提供较大铜箔面积,并可搭配过孔散热到内层或背面。
  • 在高频开关场合,应关注结温与环境温度的叠加,必要时按功率和频率进行热仿真与实际测温验证。
  • 注意器件在开关瞬态中的能量耗散(开通/关断损耗),选择合适的开关频率与驱动策略以控制总热量。

六、驱动与使用建议

  • 推荐驱动电压:10 V(在此电压下 RDS(on) 标称为 2Ω),栅极阈值为 3.5 V,表明该器件不属于典型的逻辑电平 MOSFET,使用 5V 驱动时导通性能会下降,应优先采用 >=10V 的驱动电平。
  • 栅极电荷 10 nC 意味着驱动器需能提供相应的峰值电流以实现快速开关;在高频应用中选用低阻抗驱动器可降低开关损耗。
  • 注意栅极钳位与缓冲,避免过压或振荡,必要时添加阻尼电阻和 RC 抑制网络以优化开关过渡。

七、封装与可靠性

  • TO-252(DPAK)封装利于表面贴装且装配效率高,但其散热依赖于 PCB 设计。器件工作在高压及高温环境时,应遵循英飞凌的焊接与存储规范,防止热循环引起的可靠性问题。
  • 推荐在设计阶段参考厂商完整数据手册进行电气特性、热特性和可靠性评估,确保器件在目标应用中的长期稳定运行。

总结:IPD95R2K0P7ATMA1 是一款面向高压开关场合的 N 沟道 MOSFET,950V 耐压、4A 电流级别和 TO-252 封装,使其在离线电源、PFC 以及高压驱动应用中具有实用价值。合理的驱动与散热设计是充分发挥其性能和可靠性的关键。

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.
