IMBF170R1K0M1XTMA1 产品概述

一、产品简介

IMBF170R1K0M1XTMA1 是英飞凌推出的一款碳化硅(SiC)N沟道功率 MOSFET,额定漏源电压达 1.7 kV,面向高压电力电子系统。器件采用 TO-263-7-13 封装,兼顾高电压耐受与实用的组装方式,适合中小功率高压变换与防护场景。

二、主要电气参数

  • 类型:N沟道 SiC MOSFET
  • 漏源电压 Vdss:1.7 kV
  • 连续漏极电流 Id:5.2 A
  • 耗散功率 Pd:68 W
  • 导通电阻 RDS(on):809 mΩ @ Vgs = 15 V
  • 阈值电压 Vgs(th):4.5 V
  • 总栅极电荷 Qg:5 nC
  • 输入电容 Ciss:275 pF;反向传输电容 Crss:0.7 pF
  • 工作温度范围:-55 ℃ 至 +175 ℃

三、关键特性与优势

  • 高压能力:1.7 kV 额定适合三相逆变器、牵引、HVDC 以及高压电源平台。
  • 碳化硅材料:比硅器件具有更高的击穿场强和更低的开关损耗,允许更高的开关频率和更紧凑的磁性元件设计。
  • 低栅极电荷与较小 Crss:Qg 仅 5 nC,Crss 0.7 pF,有利于快速开关并减小米勒耦合,降低切换损耗和器件受 dv/dt 影响。
  • 宽温度工作区间:可在高温环境下工作(最高至 175 ℃),提高系统可靠性与功率密度。

四、典型应用

  • 中高压整流与逆变(工业电驱、太阳能逆变器)
  • 高压开关电源与绝缘变换器
  • 电池能量管理与储能系统的高压侧功率开关
  • 受限空间且要求高温工作的电力电子模块

五、设计与使用建议

  • 栅极驱动:尽管 Vgs(th) 为 4.5 V,建议使用厂商推荐的驱动电压(典型数据表位 15 V 下的导通电阻),并严格遵守器件最大 Vgs 额定值。为控制开关应力和振荡,建议在驱动回路中使用合适的栅极阻尼(阻值依系统阻抗调整)。
  • 热管理:RDS(on) 相对较高,导通损耗不容忽视,需结合散热铜箔、散热器或强制风冷设计以维持结温在安全范围。Pd 68 W 为器件耗散能力的热设计参考,实际允许耗散取决于散热条件。
  • 抑制措施:在高 dv/dt 与过压场合推荐使用RC或RC+吸收器件(阻容/压敏)以抑制瞬态过压与振铃,保护器件安全。
  • 布局注意:保持漏源回流路径短且低阻,控制走线寄生电感以减少开关振荡与过压,应力集中处加绝缘间距。

六、封装与可靠性

TO-263-7-13 封装便于表面贴装并具备良好散热路径,适合模块化电源板设计。器件的高温等级与 SiC 特性适合长期工作在苛刻环境,但最终设计应基于英飞凌完整的可靠性与热阻数据手册进行验证。

七、总结

IMBF170R1K0M1XTMA1 是一款面向高压电力电子的 SiC MOSFET,兼顾高耐压、快速开关和宽工作温度的要求。其较低的栅极电荷和小的 Crss 有利于高频率运行,但较大的 RDS(on) 要求在实际系统中重视热设计和能耗平衡。建议在实际应用前参照英飞凌完整数据手册和仿真验证,以获得最佳性能与可靠性。

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.

Replenishment inquiry Typical RFQ workflow
